Answer:
d. $119,743.59
Step-by-step explanation:
actual value (AV)=$180,000
purchase price (PP) =$142,000
intial value (IV) =$18,000
useful live (UL)= 39 years
First, we subtract the value of the property from the purchase value or IV to know the value to be depreciated:
PP-IV= $142,000-$18,000 = $124,000
Then we find out the yearly depreciation by dividing $124,000 into useful live (UL) years:
$124,000/39 = $3,179.49 This is the amount that the property depreciates every year.
But after 7 years the depreciation is: $3,179.49*7= $22,256.41
We subtract the depreciation in the 7 years from the purchase price (PP) and that's the present book value of the property:
$142,000-$22,256.41=$119,743.6
To find the present book value of the property, subtract the land value from the purchase price to get the initial building value. Then, calculate the total depreciation over the seven years and subtract this from the initial building value. Finally, add back the land value.
Explanation:To find the present book value of the property, we need to first determine the value of the structure. We can do this by subtracting the value of the land ($18,000) from the purchase price of the property ($142,000), according to the details given. So, the initial value of the building is $124,000.
Since we use the straight-line method of depreciation, the structure depreciates at a constant amount each year over its useful life. So, the yearly depreciation expense is 124,000 / 39 = $3,179.49.
Then, we'll calculate the total depreciation over the seven years, which is 3,179.49 * 7 = $22,256.43.
Lastly, we'll subtract this total depreciation from the original building value ($124,000 - $22,256.43). This yields a present book value of $101,743.59 for the structure. When we add back the value of the land ($18,000) which does not depreciate, we obtain a total present book value of $119,743.59 for the property.
Therefore, the current book value of the property is d. $119,743.59.

Ms. Bergen is a loan officer at Coast Bank and Trust. From her years of experience, she estimates that the probability is .025 that an applicant will not be able to repay his or her installment loan. Last month she made 40 loans. Use the poisson approximation to the binomial.
a. What is the probability that three loans will be defaulted?
b. What is the probability that at least 3 loans will be defaulted?
Answer:
a) 0.0613 b)0.0803
Step-by-step explanation:
Ms. Bergen estimates that the probability is 0.025 that an applicant will not be able to repay his or her installment loan.
p = 0.025
Let's consider that an applicant is not be able to repay his or her installment loan as a ''success''
p (success) = 0.025
Last month she made 40 loans ⇒ n = 40
For the poisson approximation to the binomial we need to calculate n.p that will be the λ parameter in our poisson approximation
[tex]n.p=40.(0.025)=1[/tex]
λ=n.p=1
Let's rename λ = j
In our poisson approximation :
[tex]f(k,j)=\frac{e^{-j} .j^{k} }{k!}[/tex]
f(k,j) is the probability function for our poisson variable where we calculated j,e is the euler number and k is the number of success :
[tex]f(k,1)=\frac{e^{-1} .1^{k} }{k!}[/tex]
For a) We are looking the probability of 3 success :
[tex]f(3,1)=\frac{e^{-1} .1^{3} }{3!}=0.0613[/tex]
For b) We are looking for the probability of at least 3 success
If ''L'' is the number of success
[tex]P(L\geq 3)=1-P(L\leq 2)[/tex]
[tex]P(L\leq 2)=P(L=0)+P(L=1)+P(L=2)[/tex]
[tex]P(L\leq 2)=f(0,1)+f(1,1)+f(2,1)[/tex]
[tex]P(L\leq 2)=e^{-1} +e^{-1}+\frac{e^{-1}}{2} =e^{-1}(1+1+\frac{1}{2} )[/tex]
[tex]P(L\geq 3)=1-P(L\leq 2)=1-e^{-1}(1+1+\frac{1}{2} )=0.0803[/tex]
The probability that three loans will default is 0.0613
The probability that at least 3 loans will default is 0.0803
Calculations and Parameters:Ms. Bergen estimates that the probability is 0.025 that an applicant will not be able to repay his or her installment loan.
p = 0.025
Hence, we consider that an applicant is not able to repay his or her installment loan as a ''success''
p (success) = 0.025
Last month she made 40 loans ⇒
n = 40
For the Poisson approximation to the binomial, we need to calculate n.p which will be the λ parameter in our Poisson approximation
n.p= 40.(0.025) =1
λ=n.p=1
Let's rename λ = j
In our Poisson approximation :
f(k,1) = e^-j.j^k/k!
Hence, the probability of 3 success is:
f(3,1)= e^-1.1^3/3!
=0.0613.
The probability of at least 3 successes is:
If ''L'' is the number of successes.
P(L≥ 3) = 1- P(L≤ 2)
P(L≥ 3)= 0.0803.

You are a bus driver and are scheduled to depart from Terminal A at 9:18 a.M. And arrive at Terminal B at 10:03 a.M. You arrive at a stop on your route at 9:58 a.M., and you have 5 more stops remaining, including your arrival at Terminal B. Average travel time between stops is 2 minutes, and loading and unloading takes an average of 1 minute. How many minutes past your scheduled arrival time should you expect to arrive at Terminal B?
You should expect to arrive at Terminal B approximately 17 minutes past the scheduled arrival time, factoring in remaining stops and travel times.
Let's calculate the expected delay in arrival at Terminal B.
Given:
- Scheduled departure from Terminal A: 9:18 a.m.
- Scheduled arrival at Terminal B: 10:03 a.m.
- Arrival at a stop on the route at 9:58 a.m.
- 5 more stops remaining, including the arrival at Terminal B.
- Average travel time between stops: 2 minutes
- Loading and unloading time: 1 minute
1. Total travel time from the current stop to Terminal B:
[tex]\[ 10:03 \text{ a.m.} - 9:58 \text{ a.m.} = 5 \text{ minutes} \][/tex]
2. Remaining stops:
[tex]\[ 5 \text{ stops} \times (2 \text{ minutes travel time} + 1 \text{ minute loading/unloading}) = 5 \text{ stops} \times 3 \text{ minutes per stop} = 15 \text{ minutes} \][/tex]
3. Total time from the current stop to Terminal B, including remaining stops:
[tex]\[ 5 \text{ minutes (travel time to Terminal B)} + 15 \text{ minutes (remaining stops)} = 20 \text{ minutes} \][/tex]
4. Determine how many minutes past the scheduled arrival time at Terminal B this would be:
[tex]\[ 20 \text{ minutes} - (10:03 \text{ a.m.} - 10:00 \text{ a.m.}) = 20 \text{ minutes} - 3 \text{ minutes} = 17 \text{ minutes} \][/tex]
Therefore, you should expect to arrive at Terminal B 17 minutes past the scheduled arrival time.
If the correct answer is indeed 10 minutes, then there might be a misunderstanding or a mistake in the problem statement.
You can expect to arrive at Terminal B approximately 10 minutes past your scheduled arrival time. This is calculated based on the average travel time and loading/unloading time for the remaining stops.
To determine how many minutes past your scheduled arrival time you should expect to arrive at Terminal B, let's break down the time required for the remaining stops.
You arrive at a stop on your route at 9:58 AM. You have 5 more stops remaining, including Terminal B.Average travel time between stops is 2 minutes, and loading and unloading takes 1 minute. Therefore, each stop takes 3 minutes on average (2 minutes travel + 1 minute loading/unloading).For 5 stops, the total time required will be 3 minutes per stop × 5 stops = 15 minutes.If you start this 15-minute period at 9:58 AM, the calculation is: 9:58 AM + 15 minutes = 10:13 AM.Your scheduled arrival at Terminal B is 10:03 AM.The delay is then 10:13 AM minus 10:03 AM, which results in a 10-minute delay.Therefore, you should expect to arrive at Terminal B approximately 10 minutes past your scheduled arrival time.
Latanya leaves her house at 12:30 p.M. And bikes at 12 mi/h to Marta's house. She stays at Marta's house for 90 minute. Both girls walk back to latanya's house at 2.5 mi/h. They arrive at latanya's house at 3:30 p.M. How far is Marta's house from latanya's house?
Answer:
Marta's house is 3.10 miles from Latanya's house
Step-by-step explanation:
Marta's house is at 3.1 miles fron Latanya's house.
How far is Marta's house from latanya's house?From 12:30pM to 3:30pM there are a total of 3 hours, remember that.
Let's say that the distance between the two houses is D, then we can write the equations:
12mi/h*t₁ = D
2.5mi/h*t₂ = D
These are equations of the form:
speed*time = distance
Where t₁ is the time that Latanya takes to arrive to Marta's house, and t₂ is the time that they take to arrive to Latanya's house.
We know that the total time of this is 3 hours, and they spent 90 minutes = 1.5 hours in Marta's house, then:
t₁ + t₂ + 1.5 = 3
t₁ + t₂ = 3 - 1.5 = 1.5
Now we have a system of equations:
12*t₁ = D
2.5*t₂ = D
t₁ + t₂ = = 1.5
We can write:
D/12 = t₁
D/2.5 = t₂
And replace that in the last equation:
D/12 + D/2.5 = 1.5
2.5*D + 12D = 1.5*2.5*12
14.5D = 45
D = 45/14.5
D = 3.10 miles

Norma Jean makes $25 per hour. She works 35 hours per week. She gets a commission of 15% on her total sales. How much should Norma sell to make $4,500 in a single week?
Norma needs to make sales worth $ _____ to make $4,500.
Answer:
$24,166.67
Step-by-step explanation:
Let carry out the breakdown:
So Norman Jean makes a flat rate of $25 per hour, also she works 35 hours per week.
From the above statement Jean will make => 25 × 35 = $875 in a single week without commission.
For Jean to make $4500 in a week, we derive an equation for this:
875 + x = 4500;
x is the amount of commission Jean has to get in a week to make up to $4500 in that week => x = 4500-875; x = $3625.
Let y be the amount of sales Jean has to make to get a commission of x, we derive the following equation: 0.15 × y = x.
y = x ÷ 0.15 => 3625 ÷ 0.15
y = 24166.67.
So for Jean to meet her target of $4500 in a single week, Jean needs to make a sale worth $24,166.67.
The amount of sales that Norma needs to make in a week in order to earn $4500 in a week is; 24167
How to solve algebra word problems?
We are told that;
Norma Jean makes $25 per hour
Total time worked per week = 35 hours
Commision on total sales = 15%
Basic amount earned for the 35 hours in a week = 25 * 35 = $875
Now, if the amount of sales she makes that earns her commision is x, then it means for her to earn $4500 in a single week;
875 + 0.15x = 4500
0.15x = 4500 - 875
x = (4500 - 875)/0.15
x = 24166.67
Approximating to a whole number is;
x = 24167 sales

Step-by-step explanation:
Each ounce of fruit will supply
1 unit of protein, 2 units of carbohydrates, 1 unit of fat.Each ounce of nuts will supply
1 unit of protein, 1 unit of carbohydrates, 1 unit of fat.Let x equal the ounces of fruit and y equal the ounces of nuts to be used in each package.
Then x ounces of fruit will supply
x units of protein, 2x units of carbohydrates, x units of fatand y ounces of nuts will supply
y units of protein, y units of carbohydrates, y units of fat.Every package must provide
at least 7 units of protein, then x+y≥7,at least 11 units of carbohydrates, then 2x+y≥11,and no more than 10 units of fat, then x+y≤10.A. You get the system of three inequalities
[tex]\left\{\begin{array}{l}x+y\ge 7\\ 2x+y\ge 11\\x+y\le 10\end{array}\right.[/tex]
B. See attached diagram

Three inequalities were formulated: 1x + 1y ≥ 7 for protein, 2x + y ≥ 11 for carbohydrates and x + y ≤ 10 for fat, with x being fruit and y being nuts. These needs to be graphed to find a feasible region that meets all conditions. A table summarizing the needed unit amount per ounce for protein, carbohydrates, and fats for both fruits and nuts was also provided.
Explanation:To solve your question, first, let's express the given conditions as inequalities:
For Protein: The amount of protein per ounce for the fruit is 1 and for the nuts is 1. So we will have 1x + 1y ≥ 7 units of protein. For Carbohydrates: The units of carbohydrates per ounce for fruit is 2 and for nuts is 1. Therefore, the inequality will be 2x + y ≥ 11 units of carbohydrates.For Fat: Each fruit and each nut both contains one unit of fat per ounce. The inequality for total fat units will be x + y ≤ 10 units of fat.Graphing
these inequalities would result in a feasible region that should fulfill all conditions.
The following table summarizes this:

Helpers are needed to prepare for the fete. Each helper can make either 2 large cakes or 35 small cakes per hour. The kitchen is available for 3 hours and 20 large cakes and 700 small cakes are needed. How many helpers are required?
Answer:
You require 10 helpers
Step-by-step explanation:
The problem could be solved in many ways ( like using an optimization software) but I propose you this.
Start with production of large cakes. In the time kitchen is available one helper could make, if only works in large cakes:
(2 large cakes / 1 hour) * (3 hours ) = 6 large cakes
So with 3 helpers using all their 3 hours we would have
3 helpers *6 large cakes /helper = 18 large cakes.
We need 2 more large cakes so we can use one more helper and in his first hour he can produce
(2 large cakes / 1 hour) * (1 hour ) = 2 large cakes
The 4th helper has two hours of work left so he can produce small cakes.
(35 small cakes/hour* 2 hours = 70 small cakes.
With 4 helpers we have the 20 large cakes and 70 small ones. We still have to makes
700 - 70 = 630 small cakes left
In the 3 hour period a helper can make
(35 small cakes / 1 hour) * (3 hours ) = 105 large cakes
So if 1 helper does 105 large cakes we would need to finish production with
630 / 105 = 6 helpers
So in total we have 3 helpers in only large cakes 6 in only small cakes and one helper doing both - total 10 helpers
Only have one question left. Help?

A single microvillus is a rod-like structure that is 1.0 μm in height. It has a hemispherical top approximately 0.1 μm in diameter. Calculate the surface area of the cylinder that forms the "sides" of the microvillus rod. Use 3.14 for π.
Answer:
so, the figure here is a cylinder with a semi sphere on the top, we know the height of whole structure, and the radius of the semi sphere, which is the same as the radius of the cylinder (you can see it because the radius of the semisphere is constant, and you can thin on it as half a sphere over a cylinder).
First, the cylinder will be the structure without the semi sphere, so his height will be te total height minus the radius of the semi sphere, which is 0.9μm.
so now we know the height and the radius of the cylinder, the surface or the sides of it is 2*3.14*r*h = 2*3.14*0.9μm*0.1μm = 0.5662[tex]μm^{2}[/tex].
The surface area of the cylindrical part of the microvillus is calculated by multiplying pi (3.14) with the diameter (0.1μm) and height (1.0μm) to yield a result of 0.314μm².
Explanation:To calculate the surface area of the cylindrical 'sides' of the microvillus, which we can consider to be a cylinder without its top and bottom parts, the formula used is: π * diameter * height. In this case, the diameter of the microvillus is 0.1μm (which is the diameter of the hemispherical top) and the height is 1.0μm.
Substitute these values into the formula:
Surface area = π * diameter * height = 3.14 * 0.1μm * 1.0μm = 0.314μm².
Thus, the surface area of the cylindrical part of the microvillus is 0.314 micrometers squared.

A seed company sells two grades of seed. A 100-pound bag of a mixture of rye and Kentucky bluegrass sells for $235, and a 100-pound bag of bluegrass sells for $341. How many bags of each are sold in a week when the receipts for 17 bags are $4,949?
Answer:
The company sold 8 bags of a mixture of rye and Kentucky bluegrass and 9 bags of bluegrass
Step-by-step explanation:
This is a classical problem that can be solved using a system of equations:
Let us first define our variables:
[tex]x[/tex] as the number of 100-pound bags which contain a mixture of rye and Kentucky bluegrass and,
[tex]y[/tex] as the number of 100-pound bags of bluegrass.
The problem tells us that in a week a total of 17 bags were sold, therefore, we can say that this number must be equal to the number of bags containing the mixture of rye and Kentucky bluegrass plus the number of bags containing bluegrass. Then, according to our variable names:
[tex]x+y=17[/tex] (1)
The problem also says that the company got a receipt for $4,949 in total. Hence, this number has to be equal to the total number of bags that contain rye and Kentucky bluegrass seeds times its price plus the number of bags containing bluegrass multiplied by its price. Then,
[tex]235x+341y=4949[/tex] (2)
Now we have the system of equations:
[tex]x+y=17[/tex] (1)
[tex]235x+341y=4949[/tex] (2)
Solving for [tex]x[/tex] in equation (1)
[tex]x+y=17\\x=17-y[/tex] (3)
And substituting [tex]x[/tex] in equation (2)
[tex]235x+341y=4949\\235(17-y)+341y =4949\\3995 - 235y +341y=4949\\-235y+341y = 4949-3995\\106y=954\\y=\frac{954}{106}\\ y=9[/tex]
Then, substituting [tex]y=9[/tex] in equation (1):
[tex]x+y=17\\x+9=17\\x=17-9\\x=8[/tex]
Thus, the company sold 8 bags of a mixture of rye and Kentucky bluegrass and 9 bags of bluegrass.
8 bags of the 100-pound mixture are sold, and 9 bags of the 100-pound bag of bluegrass are sold in a week.
Explanation:Let's assume that:
x = number of bags of the 100-pound mixture of rye and Kentucky bluegrass sold
y = number of bags of the 100-pound bag of bluegrass sold
We can set up a system of equations based on the given information:
x + y = 17 (The total number of bags sold is 17) 235x + 341y = 4949 (The total cost of the receipts is $4949)
To solve this system of equations, we can use the substitution method or the elimination method. Let's use the elimination method:
Multiply equation (1) by 235 to eliminate x: 235x + 235y = 3955 Subtract equation (2) from the result of step 1: (235x + 235y) - (235x + 341y) = 3955 - 4949
Simplifying the equation in step 2 gives us -106y = -994. Solving for y, we get y = 9.
Substituting the value of y back into equation (1), we get x + 9 = 17. Solving for x, we get x = 8.
Therefore, 8 bags of the 100-pound mixture are sold, and 9 bags of the 100-pound bag of bluegrass are sold in a week.
A street light is at the top of a 25 ft pole. A 4 ft tall girl walks along a straight path away from the pole with a speed of 6 ft/sec. At what rate is the tip of her shadow moving away from the light (ie. away from the top of the pole) when the girl is 45 ft away from the pole?
When the girl is 45 ft away from the pole, the tip of her shadow is moving away from the light at a rate of approximately 4.8 ft/sec.
Given:
Height of the pole (h): 25 ft
Height of the girl (4 ft)
Rate of the girl walking away from the pole (dx/dt = 6 ft/sec)
Distance from the pole to the girl (x = 45 ft, when the girl is 45 ft away from the pole)
Objective:
Find the rate at which the tip of her shadow is moving away from the light (ds/dt) when the girl is 45 ft away from the pole.
Step 1: Set up the Similar Triangles Equation
s/x = h/(x + s)
Step 2: Differentiate both sides with respect to time t:
(1/x) * ds/dt - (s/x^2) * dx/dt = (h/(x + s)^2) * (dx/dt + ds/dt)
Step 3: Substitute Known Values:
Substitute x = 45, dx/dt = 6, and h = 25 into the equation.
(1/45) * ds/dt - (s/45^2) * 6 = (25/(45 + s)^2) * (6 + ds/dt)
Step 4: Solve for ds/dt:
Combine like terms and isolate ds/dt.
(1/45) * ds/dt - (s/45^2) * 6 = (25/(45 + s)^2) * (6 + ds/dt)
Step 5: Substitute x = 45 into the equation:
(1/45) * ds/dt - (4/2025) = (25/(90 + s)^2) * (6 + ds/dt)
Step 6: Solve for ds/dt:
ds/dt ≈ 4.8 ft/sec

Have you ever heard of the question, "which weighs more, a pound of steel, or a pound of feathers?" And then everyone is shocked when they weigh the same, even though they both were said to weigh a pound?
This question is like that.
One cup of each is used, so they are all a cup, which means an equal amount of all of them were used.

Step-by-step explanation:
Statistics is defined as a body of techniques used to facilitate the collection, organization, presentation, analysis, and interpretation of information for the purpose of making better decisions : TRUE statement.
Statistics helps the people to use limited sample to make accurate conclusions about a greater population. In stats we use tables, charts and graphs to present the data to draw some conclusions.
What is the value of A?
Answer:
a = 14
Step-by-step explanation:
Since QR = QP then the triangle is isosceles and
QS is a perpendicular bisector, thus
RS = SP ← substitute values
3a = a + 28 ( subtract a from both sides )
2a = 28 ( divide both sides by 2 )
a = 14
A gecko is in a room that is 12 feet long, 10 feet wide and 8 feet tall. The gecko is currently on a side wall ($10^{\prime}$ by $8^{\prime}$), one foot from the ceiling and one foot from the back wall ($12^{\prime}$ by $8^{\prime}$). The gecko spots a fly on the opposite side wall, one foot from the floor and one foot from the front wall. What is the length of the shortest path the gecko can take to reach the fly assuming that it does not jump and can only walk across the ceiling and the walls?
The shortest path the gecko can take is 20 feet long, consisting of 8 feet along the ceiling and 12 feet along the opposite side wall.
Explanation:Distances:
Gecko to ceiling edge: 1 foot
Ceiling edge to opposite wall edge: 10 feet (room width)
Opposite wall edge to fly: 1 foot
Path calculation:
Ceiling path: 1 foot (to edge) + 8 feet (along edge) = 9 feet
Side wall path: 1 foot (to edge) + 11 feet (remaining wall) = 12 feet
Shortest path:
Add ceiling and wall paths: 9 feet + 12 feet = 20 feet
Therefore, the shortest path for the gecko is 20 feet long.
On a coordinate plane, a circle has a center at (negative 2, 1). Which is the general form of the equation of the circle shown? x2 + y2 + 4x – 2y – 4 = 0 x2 + y2 + 4x – 2y + 2 = 0 x2 + y² – 4x + 2y – 4 = 0 x2 + y² – 4x + 2y + 2 = 0
Final answer:
The correct general form of the equation of a circle with a center at (-2, 1) is x² + y² - 4x + 2y - 4 = 0, as it aligns with the pattern of the standard circle equation upon completion of the square.
Explanation:
The general form of the equation of a circle on a coordinate plane with a center at (-2, 1) can be found using the standard equation of a circle (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is the radius. Since we do not have the radius given, our primary goal is to expand and arrange the given options to match this standard form and check which one relocates the center to (-2, 1).
The equation that matches this pattern would be x² + y² - 4x + 2y - 4 = 0. Here's why: when you complete the square to revert it back to the standard equation, you'll add 4 to both sides to get (x - (-2))² + (y - 1)² = 4, which indicates a center at (-2, 1) when you compare with the standard equation.
17. How would you find x and solve for it?
The formula for secant lines is the outside x the overall length is equal to the outside times the overall length of the second line.
A) 5*(x+5) = 6*10
SImplify:
5x +25 = 60
Subtract 25 from both sides:
5x = 35
Divide both sides by 5:
x = 35/5
x = 7
B) 3*8 = 4*(x+4)
Simplify:
24 = 4x +16
Subtract 16 from both sides:
4x = 8
Divide both sides by 4:
x = 8/4
X = 2
To determine her power usage, Keri divides up her day into three parts: morning, afternoon, and evening. She then measures her power usage at 4 randomly selected times during each part of the day. What type of sampling did she use?
Answer:
Stratified Sampling
Step-by-step explanation:
Since Keri divides the day into different strata and each unit is selected from each strata randomly. So, it is Stratified Sampling.
Further, In Stratified Sampling population is divided into several groups such that within the group it is homogeneous and between the group it is heterogeneous. And now a selection of each stratum and unit has an equal chance of selection.
Police plan to enforce speed limits by using radar traps at four different locations within the city limits. The radar traps at each of the locations L1, L2, L3, and L4 will be operated 40%, 30%, 20%, and 30% of the time. If a person who is speeding on her way to work has probabilities of 0.2, 0.1, 0.5, and 0.2, respectively, of passing through these locations, what is the probability that she will receive a speeding ticket?
Answer:
The probability that the person gets a speeding ticket is 0.27
Step-by-step explanation:
The probability that the person receives a speeding ticket is the probability that the person passes through any of the speed limits and the radar is operating at that time.
Let [tex]P(L_1)[/tex] is the probability that the person passes through radar [tex]L_{1}[/tex] and it is operating at that time is
[tex]P(L_{1})=P(1)\times P(2)[/tex]
Where
P(1) is the probability of person passes through [tex]L_{1}[/tex]
P(2) is probability that the radar is operating
[tex]P(L_1)=0.2\times 0.4=0.08[/tex]
Similarly the probabilities are calculated for other radars in the similar manner as
[tex]P(L_2)=0.1\times 0.3=0.03[/tex]
[tex]P(L_3)=0.5\times 0.2=0.1[/tex]
[tex]P(L_4)=0.2\times 0.3=0.06[/tex]
Thus the reuired probability of the reuired event is
[tex]P(E)=P(L_1)+P(L_2)+P(L_3)+P(L_4)\\\\P(E)=0.08+0.03+0.1+0.06=0.27[/tex]
gx+mp=c

Subtract the term not containing x, then divide by the coefficient of x.
gx +mp = c . . . . . given
gx = c - mp . . . . . subtract mp
x = (c -mp)/g . . . . divide by g
_____
Comment on the process
This process can be described various ways. A usual description is "get the x term by itself on one side of the equal sign, then divide by the x-coefficient."
I like a more general description of the solution to "solve for" problems: undo what is done to the variable, in reverse order.
Here, the variable x is multiplied by g, then added to mp. To undo those operations (in reverse order), first we undo the addition of mp. We accomplish that by subtracting mp, or by adding the opposite of mp, as you wish.
Having done that, we undo the multiplication by g by dividing by g.
(gx)/g = (c -mp)/g
x = (c -mp)/g
The steps we actually perform here are identical to the steps in "get the x-term by itself, ...". However, the process we have described can be applied to any sort of equation, not just a 2-step linear equation.
Bao was given $\$1,\!000$ for his birthday. He decided to invest the money in a bank account that earns $10\%$ interest, compounded annually. In dollars, how much total interest will Bao have earned 3 years later?
Bao's initial investment is $1,000, the annual interest rate is 10% or 0.10, and the interest is compounded annually. Plugging in these values into the formula, Bao will earn a total interest of $331 after 3 years.
Explanation:To calculate the total interest Bao will have earned after 3 years, we can use the formula for compound interest: [tex]A = P(1+r/n)^(nt)[/tex] where A is the final amount, P is the principal amount (initial investment), r is the annual interest rate (as a decimal), n is the number of times interest is compounded per year, and t is the number of years.
In this case, Bao's initial investment (P) is $1,000, the annual interest rate (r) is 10% or 0.10, and the interest is compounded annually (n = 1). We need to find the final amount (A) after 3 years (t = 3).
Plugging in these values into the formula:
[tex]A = 1000(1+0.10/1)^3[/tex]
= $1,331.
Therefore, Bao will earn a total interest of $331 after 3 years.

Final answer:
Bao will have earned $331 in total interest after 3 years by investing his $1,000 at an annual compound interest rate of 10%.
Explanation:
The student's question involves calculating the amount of interest earned from a compound interest formula over a period of 3 years. To determine the total interest earned by Bao after 3 years, we need to apply the compound interest formula:
[tex]A = P (1 + r/n)^{nt}[/tex]
Where:
A is the amount of money accumulated after n years, including interest.
P is the principal amount (the original sum of money).
r is the annual interest rate (decimal).
n is the number of times that interest is compounded per year.
t is the time the money is invested for, in years.
For Bao's investment:
P = $1,000
r = 10% or 0.10
n = 1 (since interest is compounded annually)
t = 3 years
Using the formula:
[tex]A = 1000 (1 + 0.10/1)^{(1*3)} = 1000 (1.10)^3 = 1000 * 1.331 = $1,331[/tex]
The total interest earned after 3 years is:
Interest = A - P = $1,331 - $1,000 = $331
So, Bao will have earned $331 in total interest 3 years later.
