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

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.

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.

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.

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.

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

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.

Therefore, you should expect to arrive at Terminal B approximately 10 minutes past your scheduled arrival time.

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

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

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.

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

Answer:

Step-by-step explanation:

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.

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)

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.

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.

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.

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.

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.

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:

To solve this system of equations, we can use the substitution method or the elimination method. Let's use the elimination method:

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.
