Answer:

The answer to your question is: 4.2 x 10⁻²

Step-by-step explanation:

Information: (3 x 10⁶) x (1.4 x 10⁻⁸)

                    3 x 1.4 = 4.2                                   we just multiply the integers

                   10⁶ + 10⁻⁸ = -2                                then we add 6 and -8

                   4.2 x 10⁻²                                   now join the results and -2 will be a power of ten.

Answer:

13665.6 deaths per year

Step-by-step explanation:

We can determine certain statistics based on the information. If 15567 patients where discharge and 245 deaths were recorded, the total number of patients were:

[tex]=15567+245=15812[/tex]

If 75 deaths occured in the first 48 hours we have a death rate of:

[tex]=75/48=1.56[/tex]

1.56 deaths per hour.

We want the death rate per year. If we have the death rate per hour we can determine the death rate per year:

[tex]1.56\cdot{24}\cdot{365}=13665.6[tex]

13665.6 deaths per year

The correct net death rate for the year is [tex]\(\frac{172}{15567}\).[/tex]

To calculate the net death rate for the year, we need to consider the total number of deaths that occurred and the total number of discharges. The net death rate is calculated by dividing the number of deaths by the number of discharges.

 From the given statistics, we have:

- Total discharges: 15,567

- Total deaths: 245

 However, we need to adjust the total deaths to account for the deaths that occurred under 48 hours and the medical examiner's cases, as these might not be included in the net death rate calculation.

- Deaths under 48 hours: 75

- Medical examiner's cases: 8

 The deaths under 48 hours and the medical examiner's cases are typically excluded from the net death rate calculation because they may not reflect the quality of care provided by the hospital. Therefore, we subtract these from the total deaths:

Adjusted deaths = Total deaths - Deaths under 48 hours - Medical examiner's cases

Adjusted deaths = 245 - 75 - 8

Adjusted deaths = 162

 Now, we can calculate the net death rate:

Net death rate =[tex]\(\frac{\text{Adjusted deaths}}{\text{Total discharges}}\)[/tex]

Net death rate = [tex]\(\frac{162}{15567}\)[/tex]

This gives us the net death rate for the year based on the adjusted number of deaths."

Answer:

  91.8 ft

Step-by-step explanation:

So we can talk about the diagram, let's name a couple of points. The base of the tree is point T, and the top of the tree is point H. We want to find the length of TH given the length AB and the angles HAT and ABT.

The tangent function is useful here. By its definition, we know that ...

  TA/BA = tan(∠ABT)

and

  TH/TA = tan(∠HAT)

Then we can solve for TH by substituting for TA. From the first equation, ...

  TA = BA·tan(∠ABT)

From the second equation, ...

  TH = TA·tan(∠HAT) = (BA·tan(∠ABT))·tan(∠HAT)

Filling in the values, we get ...

  TH = (24.8 ft)tan(87.3°)tan(9.9°) ≈ 91.8 ft

The height h of the tree is about 91.8 ft.

Answer:

Option A - 342 feet

Step-by-step explanation:

Given : Janice puts a fence around her rectangular garden. The garden has a length that is 9 feet less than 3 times its width.

To find : What is the perimeter of Janice fence if the area of her garden is 5,670 square feet?

Solution :

Let the width of the garden be w=x feet.

The garden has a length that is 9 feet less than 3 times its width.

The length of the garden be l=3x-9 feet

The area of the garden is A=5670 square feet.

The formula of area of garden is [tex]A=l\times w[/tex]

[tex]5670=(3x-9)\times x[/tex]

[tex]5670=3x^2-9x[/tex]

[tex]3x^2-9x-5670=0[/tex]

[tex]x^2-3x-1890=0[/tex]

[tex]x^2-45x+42x-1890=0[/tex]

[tex]x(x-45)+42(x-45)=0[/tex]

[tex](x-45)(x+42)=0[/tex]

[tex]x=45,-42[/tex]

Reject x=-42 as measurement cannot be negative.

The width of the garden is w=45 feet.

The length of the garden is l=3(45)-9=135-9=126 feet.

The perimeter of the garden is [tex]P=2(l+w)[/tex]

[tex]P=2(126+45)[/tex]

[tex]P=2(171)[/tex]

[tex]P=342[/tex]

The perimeter of Janice fence is 342 feet.

Therefore, Option A is correct.

The perimeter of Janice's fence is: [tex]\[ {342 \text{ feet}} \][/tex]

To determine the perimeter of Janice's garden, let's follow these steps:

Step 1: Define Variables

Let ( w ) be the width of the garden in feet.

The length ( l ) of the garden is given by: [tex]\[ l = 3w - 9 \][/tex]

Step 2: Set Up the Area Equation

The area of the rectangular garden is given as 5,670 square feet:

[tex]\[ \text{Area} = l \times w \][/tex]

[tex]\[ 5670 = (3w - 9) \times w \][/tex]

Step 3: Solve the Quadratic Equation

Expand and simplify the equation:

[tex]\[ 5670 = 3w^2 - 9w \][/tex]

Rearrange it to standard quadratic form:

[tex]\[ 3w^2 - 9w - 5670 = 0 \][/tex]

Step 4: Factor or Use the Quadratic Formula

Divide through by 3 to simplify:

[tex]\[ w^2 - 3w - 1890 = 0 \][/tex]

Solve using the quadratic formula [tex]\( w = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \)[/tex]:

[tex]\[ a = 1, \, b = -3, \, c = -1890 \][/tex]

[tex]\[ w = \frac{-(-3) \pm \sqrt{(-3)^2 - 4 \cdot 1 \cdot (-1890)}}{2 \cdot 1} \][/tex]

[tex]\[ w = \frac{3 \pm \sqrt{9 + 7560}}{2} \][/tex]

[tex]\[ w = \frac{3 \pm \sqrt{7569}}{2} \][/tex]

[tex]\[ w = \frac{3 \pm 87}{2} \][/tex]

This gives two potential solutions:

[tex]\[ w = \frac{90}{2} = 45 \][/tex]

[tex]\[ w = \frac{-84}{2} = -42 \][/tex]

Since width cannot be negative:

[tex]\[ w = 45 \][/tex]

Step 5: Find the Length

Substitute ( w = 45 ) into the length equation:

[tex]\[ l = 3(45) - 9 \][/tex]

[tex]\[ l = 135 - 9 \][/tex]

[tex]\[ l = 126 \][/tex]

Step 6: Calculate the Perimeter

[tex]\[ P = 2l + 2w \][/tex]

[tex]\[ P = 2(126) + 2(45) \][/tex]

[tex]\[ P = 252 + 90 \][/tex]

[tex]\[ P = 342 \][/tex]

Thus, the perimeter of Janice's fence is: [tex]\[ {342 \text{ feet}} \][/tex]

Answer: now, the expected value will be x = p1*0$ + p2*1$

where p1 is te probabilty of a fail and p2 the probability of succes.

Ok, we will have 4 steps here.

1) there are 4 balls, and if we chose a spesific colour, there are 50% chance of succes. x = 0.5$

2) there are 3 balls, but yo know that if in the first step you graved a blue ball, then here you have a 66% of getting a red one, so if you play optimaly, you will guess red. x = 0.6$

3a) now there are two posibilities, in the last step yo get the other blue ball, so now are two red balls in the box, and you have guaranted 2 bucks. x = 2$ (but you failed in the last step)

3b) if in 2 you get a red ball, then again you have a 50/50 chance for each colour. x= 0.5$

4) there's only one ball in the box, you get a dollar x = 1 $

so if you go with the 3b path, te expected value will be 2.6$

with 3a) x = 2.5$

The expected value of playing this game, if you play optimally, is $0.83.

To calculate the expected value of this game, we need to determine the probability of each outcome and multiply it by the corresponding payout. Let's start with the first draw:

For the second draw, there are two possibilities:

To calculate the expected value, we multiply each outcome by its probability and sum them up:

(2/4) * $1 + (2/4) * $1 + (1/3) * $1 + (1/3) * $1 = $0.83

The expected value of this game, if you play optimally, is $0.83.

Answer:

B. $25,069

Step-by-step explanation:

An interest of 6% per year, compounded monthly it means that he earns 6/12% = 0.5% of what he has invested every month.

If he invests x money what he will have the first month will be :

Money = x*(1+0.005)

The next month:

Money' = Money*(1+0.005) = x *(1+0.005)(1+0.005) = x* (1+0.005)^2

Therefore in this type of interest the formula is:

Money = x*(1+r)^n

Where:

x is the money invested the first time

r is the interest

n is the number of periods

For this problem:

x = what you have to find

r = 0.005

n = 3 years (1 period is 1 month) then the period is 36 months

Money = 30000

Replacing:

30000 = x * (1+0.005)^36

x = 25,069

Final answer:

To make a $30,000 down payment in three years with an account earning 6% interest compounded monthly, James needs to deposit approximately $25,189.06 today.

Explanation:

Calculating the Present Value for a Future Goal

To achieve a $30,000 down payment in three years with an account that earns 6% interest per year, compounded monthly, we need to calculate the present value of the future goal. Since the interest is compounded monthly, we use the present value formula for compound interest, which is P = A / (1 + r/n)^(nt), where P is the present value, A is the future amount, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

Here, A = $30,000, r = 0.06 (6% converted to decimal), n = 12 (compounded monthly), and t = 3.
So, P = $30,000 / (1 + 0.06/12)^(12*3) = $30,000 / (1 + 0.005)^(36) ≈ $30,000 / 1.191016 = $25,189.06 (rounded to 2 decimal places).

The amount James needs to deposit today is approximately $25,189.06.

Answer: 4,85 meters

Step-by-step explanation:

Using energy we get the velocity when the man gets to the bottom of the hill

mgh=1/2 m v^2

Then the velocity is the squareroot of two times the mass times the gravity constant =9,598 m/s2

Using energy again, we can get the velocity on the edge of the ledge (using the second mass, the one of the man plus the backpack)

1/2 M1 V1^2=1/2 M2 V2^2

We get V2=8,24 m/s2

Then we have to analyze the jump, horizontally, with constant velocity, and vertically, with constant acceleration equals to the gravity constant.

To get the time we analyze the vertical move

Y=1/2 g t^2

t=59 seconds

To get the horizontal distance we use

X= v t

X=4,85 meters.

[tex]x_{m}=\frac{x_{1} +x_{2} } {2}, y_{m} =\frac{y_{1}+ y_{2} }{2}[/tex]

2) Each segment has two endpoints, and their midpoints, namely:

a) (1,-9) and its midpoint (2,-1)

b) (-2,18) and its midpoint (5,9)

Step-by-step explanation:

There are 1.61 km in 1 mi.

10 mi × (1.61 km/mi) = 16.1 km

Answer:

Step-by-step explanation:

You may recognize that you are given two relationships between two unknowns. You can write equations for that.

You are asked for numbers of adult tickets and of student tickets. It often works well to let the values you're asked for be represented by variables. We can choose "a" for the number of adult tickets, and "s" for the number of student tickets. Then the problem statement tells us the relationships ...

  a + s = 800 . . . . . . 800 tickets were sold

  12.50a + 7.50s = 8600 . . . . . . . revenue from sales was 8600

(You are supposed to know that the revenue from selling "a" adult tickets is found by multiplying the ticket price by the number of tickets: 12.50a.)

___

You can solve these two equations any number of ways. One way is to do it by elimination. We can multiply the first equation by 12.50 and subtract the second equation:

  12.50(a +s) -(12.50a +7.50s) = 12.50(800) -(8600)

  5s = 1400 . . . . simplify. (The "a" variable has been eliminated.)

  s = 280 . . . . . . divide by 5

Then the number of adult tickets can be found from the first equation:

  a + 280 = 800

  a = 520

280 student tickets and 520 adult tickets were sold.

520 adult tickets and 280 student tickets were sold.

To solve this problem, we need to set up a system of two linear equations using the given information and then solve for the number of adult and student tickets sold.

Let x be the number of adult tickets sold, and y be the number of student tickets sold.

Given information:

- Total number of tickets sold: [tex]x + y = 800[/tex]

- Total receipts: [tex]12.50x + 7.50y = 8600[/tex]

We have a system of two equations with two unknowns:

[tex]x + y = 800[/tex]

[tex]12.50x + 7.50y = 8600[/tex]

We can solve this system using the substitution method or the elimination method.

Using the substitution method:

From the first equation, [tex]y = 800 - x[/tex]

Substituting this into the second equation:

[tex]12.50x + 7.50(800 - x) = 8600[/tex]

[tex]12.50x + 6000 - 7.50x = 8600[/tex]

[tex]5x = 2600[/tex]

[tex]x = 520[/tex]

Substituting [tex]x = 520[/tex] into the first equation:

[tex]y = 800 - 520 = 280[/tex]

Therefore, 520 adult tickets and 280 student tickets were sold.

By setting up a system of linear equations based on the given information and solving them using algebraic methods, we can find the number of adult and student tickets sold that satisfy the conditions of the total number of tickets and the total receipts.

The x = the number of hours traveled by plane.

-------------------------------------------------

Equation:

train distance + plane distance = 1300 miles

50x + 275x = 1300

x(325) = 1300

x = 4 hours

---

The trip took 8 hrs.

Step-by-step explanation:

Trust me

Answer:

The answer to your question is: time = 4 hours

Step-by-step explanation:

Data

Total distance = 1300 miles

train v = 50 mi/h      time is the same        distance = x

plane v = 275 mi/h                                      distance = 1300 - x

t = ?

Formula

v = d/t

Process

Train  t = d/v           t = x / 50

Plane  t = d/ v         t = (1300 - x) / 275

                   x / 50   =  (1300 - x) / 275

                  275 x  = 50 (1300 - x)

                  275 x = 65000 - 50x                   solve for x

                  275x + 50x = 65000

                  325x = 65000

                  x = 65000/325

                  x = 200

   Time with train

                                t = 200 / 50 = 4 hours

Time with plane

                               t = (1300 - 200) / 275

                               t = 1100 / 275 = 4 hours

Final answer:

Approximately 0.3% of IQ scores are greater than 133 according to the empirical rule, which states that 99.7% of values fall within three standard deviations of the mean in a bell-shaped distribution.

Explanation:

Using the empirical rule (also known as the 68-95-99.7 rule) for a bell-shaped distribution, we can determine the percentage of IQ scores that fall at different distances from the mean.

A score of 133 is three standard deviations above the mean (since the mean is 97 and the standard deviation is 12, 97 + 3(12) = 133). According to the empirical rule, approximately 99.7% of IQ scores fall within three standard deviations of the mean. Therefore, to find the percentage of scores greater than 133, we subtract the bottom 99.7% from 100%, resulting in approximately 0.3%.

Thus, following the empirical rule, 0.3% of IQ scores are greater than 133.

6 km = 6000 m

8 km = 8000 m

Volume = 0.01 m x 6000 m x 8000 m =  480000 m³

480000 m³ = 480000000 kg of water (density of water = 1000kg/m³)

103 kg = 1 metric ton

480000000 kg = 480000000 / 103 = 4660194 metric ton

1 m³ = 264.17 gallon

480000 m³ = 480000 x 264.172 = 126802560 gallon

A total of 480,000 metric tons of water fell on the city, which is equivalent to approximately 126,802,560 gallons of water.

To calculate the amount of water in metric tons that fell on the city, we need to first determine the volume of the rainfall which can be calculated by taking the product of the rainfall's depth (1.0 cm), and the area of the city (6 km x 8 km).

Firstly, convert all dimensions into the same unit. Let's use meters: 1.0 cm = 0.01 m, 6 km = 6000 m, 8 km = 8000 m. Therefore, the volume equals 0.01 m x 6000 m x 8000 m = 480,000 m³.

The mass of the water is then found by multiplying the volume by the density of water. Given that the density of water is 1 g/cm³ (or 1000 kg/m³, which is more useful here, as mass needs to be in kg), this calculation gives us a mass of 480,000,000 kg = 480,000 metric tons.

To convert this to gallons, we use the fact that 1 m³ = 264.172 gallons. Therefore, 480,000 m³ = 480,000 x 264.172 = 126,802,560 gallons.

To determine which option is a factor of the given expression, we need to check each option individually. After checking, we find that option 2, 2x^2 + 7y, is a factor.

To determine which of the given options is a factor of the expression 24x^6 - 1029y^3, we need to check each option individually.

Option 1: 24 - We can verify if 24 is a factor by dividing 24x^6 - 1029y^3 by 24 and checking if there is no remainder.

Option 2: 2x^2 + 7y - We can substitute values for x and y and simplify the expression to see if it equals zero for any values.

Option 3: 4x^4 + 14x^2y + 49y^2 - We can substitute values for x and y and simplify the expression to see if it equals zero for any values.

and 5*-3 is -15

making the equations match

The factored form of the expression 10x⁵ + 5x² - 15 is 5(x⁵ + x² - 3).

A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product because the product is divisible by them.

Given, A polynomial of degree five which is 10x⁵ + 5x² - 15.

Now, The HCF of 10, 15, and 5 is 5, and the HCF of x⁵, x², and x⁰ is x⁰ = 1.

Therefore,

10x⁵ + 5x² - 15.

= 5x⁰(x⁵ + x² - 3).

= 5(x⁵ + x² - 3).

Answer:

The answer to your question is: 35 questions worth 2 points and 15 questions worth 3 points.

Step-by-step explanation:

Data

Number of questions = 50

Total points = 115

x = questions worth 2 points

y = questions worth 3 points

Process

write to equations

(1)  ---------------    x + y = 50

(2) --------------    2x + 3y = 115

Solve them by substitution

           x = 50 - y

         2 (50 - y) + 3y = 115

          100 - 2y + 3y = 115

           3y -2 y = 115 - 100

                     y = 15

           x = 50 - 15

            x = 35
