8. A graph represents the proportional relationship between the number of pages printed, y, and the time in minutes, x. If there is a point on the graph at (4, 720), how many pages can be printed in half a minute?​

Answers

Answer 1

The number of pages that can be printed in half a minute is 90 pages

How many pages can be printed in half a minute?​

From the question, we have the following parameters that can be used in our computation:

The graph represents a  proportional relationship

Where

x = minutes

y = pages

When the time is half a minute, we have

x = 0.5

So, we have the following ordered pair

(0.5, y)

From the question. we have

(4, 720)

So, we have

(0.5, y) = (4, 720)

Express as an equation

So, we have

y/0.5 = 720/4

This gives

y = 0.5 * 720/4

Evaluate

y = 90

Hence, the number of pages is 90

You currently have $6,500 that you would plan to deposit into an investment account that has an anticipated growth factor of 1.03 per year. Use guess and check to estimate the number of years that it will take for this investment to grow to $10,000. Show your work.​

Answers

Answer:

Using guess and check, we can estimate the number of years it will take for the investment to grow to $10,000 as follows:

First, we'll assume that it will take 5 years for the investment to grow to $10,000.

After 5 years, the investment would grow to:

$6,500 x 1.03^5 = $7,960.35

Since this is still less than $10,000, we need to increase the number of years.

Next, we'll assume that it will take 10 years for the investment to grow to $10,000.

After 10 years, the investment would grow to:

$6,500 x 1.03^10 = $9,020.14

Since this is still less than $10,000, we need to increase the number of years again.

Finally, we'll assume that it will take 15 years for the investment to grow to $10,000.

After 15 years, the investment would grow to:

$6,500 x 1.03^15 = $10,005.58

Since this is slightly more than $10,000, we can estimate that it will take around 15 years for the investment to grow to $10,000.

Therefore, the estimated number of years it will take for the investment to grow to $10,000 is about 15 years.

a) Find the joint probability function f(x, y)
b) Find the joint probability distribution of f(x, y)

Answers

The requreid, the joint probability function f(x, y) is:

f(0,0) = 3/14

f(0,1) = 9/28

f(0,2) = 3/28

f(1,0) = 9/28

f(1,1) = 9/28

f(2,0) = 3/14

f(2,1) = 3/14

f(3,0) = 1/14

To evaluate the joint probability function f(x, y), we need to determine the probability of selecting x black balls and y blue balls out of a sample of 4 balls. We can do this using the hypergeometric probability distribution formula:

f(x,y) = P(X = x, Y = y) = (C(3, x) * C(2, y) * C(3, 4-x-y)) / C(8, 4)

where C(n, k) represents the number of combinations of k items chosen from a set of n items.

Plugging in the values, we get:

f(0,0) = (C(3,0) * C(2,0) * C(3,4-0-0)) / C(8,4) = 3/14

f(0,1) = (C(3,0) * C(2,1) * C(3,4-0-1)) / C(8,4) = 9/28

f(0,2) = (C(3,0) * C(2,2) * C(3,4-0-2)) / C(8,4) = 3/28

f(1,0) = (C(3,1) * C(2,0) * C(3,4-1-0)) / C(8,4) = 9/28

f(1,1) = (C(3,1) * C(2,1) * C(3,4-1-1)) / C(8,4) = 9/28

f(2,0) = (C(3,2) * C(2,0) * C(3,4-2-0)) / C(8,4) = 3/14

f(2,1) = (C(3,2) * C(2,1) * C(3,4-2-1)) / C(8,4) = 3/14

Answers

Answer:

To find the probability that a person surveyed is under 40 given that he or she gets the news by reading the paper, we need to use Bayes' theorem:

P(Under 40 | Read paper) = P(Read paper | Under 40) * P(Under 40) / P(Read paper)

where

P(Under 40 | Read paper) is the probability that a person is under 40 given that he or she gets the news by reading the paper

P(Read paper | Under 40) is the probability that a person under 40 reads the paper (36/80)

P(Under 40) is the overall probability of selecting a person under 40 (40/80)

P(Read paper) is the overall probability of selecting a person who reads the paper, calculated as the sum of those who are under 40 and read the paper and those who are 40 or older and read the paper (36+24)/(80)

Plugging in the values, we get:

P(Under 40 | Read paper) = (36/80) * (40/80) / ((36+24)/80)

P(Under 40 | Read paper) = 0.6

So the probability that a person surveyed is under 40, given that he or she gets the news by reading the paper, is 60%.

Answers

The total amount paid to harry in past week, is 299.28.

We know that,

Amount is the sum or the total value.

For example, if A purchase 2 kg rice at the price of 40 rs/kg, the amount will be 40×2= 80 rs.

Given that,

The amount paid to Harry for 1 hour = $8.60

Since, Harry worked for 33 hours,

So, The amount paid to Harry for 33 hours = 8.60×33=283.8

Harry gets half times more amount than hourly rate and also gets bonus for last 3 days

So for last 3 days the extra amount paid to Harry

= 3×1/2×8.60+3×1/10×8.60

= 12.9+2.58

Answers

The function that is most likely increase exponentially is f(x). Because it eventually exceeds g(x)

To determine which function is most likely increasing exponentially, we need to compare the rate at which the two functions are increasing.

Looking at the table, we can see that as x increases, f(x) increases at a faster rate than g(x). In fact, f(x) eventually exceeds g(x) for x values greater than or equal to 5. This suggests that f(x) is increasing at an exponential rate.

On the other hand, g(x) is increasing at a much slower rate than f(x). Although g(x) is also increasing, it does not appear to be increasing exponentially. In fact, g(x) will never exceed f(x), because f(x) grows at a faster rate.

Therefore, the function that is most likely increase exponentially is f(x).

Answers

Sure, I can help you with that!

To write the function g(x) = -1/2x^2 + 2x + 5 in vertex form, we need to complete the square. We can start by factoring out the coefficient of x^2, which is -1/2:

g(x) = -1/2(x^2 - 4x) + 5

Next, we need to add and subtract a constant term inside the parentheses that will allow us to complete the square. To do this, we take half of the coefficient of x, square it, and then add and subtract the result:

g(x) = -1/2(x^2 - 4x + 4 - 4) + 5

Notice that we added and subtracted 4, which is (1/2 * -4)^2. This allows us to complete the square and factor the quadratic as a perfect square trinomial:

g(x) = -1/2(x - 2)^2 + 7

So the function g(x) in vertex form is:

g(x) = -1/2(x - 2)^2 + 7

The vertex is (2, 7) and the parabola opens downwards.

In the initial value problem the value of f(π/5) ≅ -5.26

How to solve the initial value problem?

Given the initial value problem f"(x) = -25sin(5x) and f'(0) = 3 and f(0) = -2, we desire to find f(π/5). We proceed as follows

f"(x) = -25sin(5x)

Integrating both sides of the equation, we have that

∫f"(x) = ∫-25sin(5x)

f'(x) = -25∫sin(5x)

f'(x) = -25∫sin(5x)

f'(x) = -25(-cos(5x))/5 + C

f'(x) = 5cos(5x) + C

Given that f'(0) = 3, substituting the values of the variables into the equation, we have that

f'(x) = 5cos(5x) + C

f'(0) = 5cos(5(0)) + C

3 = 5cos(0) + C

3 = 5(1) + C

3 = 5 + C

C = 3 - 5

C = -2

So, we have that f'(x) = 5cos(5x) - 2

To find f(x), we integrate f'(x). So, we have that

f'(x) = 5cos(5x) - 2

∫f'(x) = ∫(5cos(5x) - 2)dx

f(x) = ∫5cos(5x)dx - ∫2dx

= 5sin(5x)/5 - 2x + C'

f(x) = sin(5x) - 2x + C'

Since f(0) = -2, we have that

f(0) = sin(5(0)) - 2(0) + C'

-2 = sin0 - 0 + C'

- 2 = 0 - 0 + C'

- 2 = 0 + C'

C' = -2

So, substituting C' into the equation, we have that

f(x) = sin(5x) - 2x + C'

f(x) = sin(5x) - 2x - 2

So, to find f(π/5), substituting this into the equation, we have that

f(π/5) = sin(5π/5) - 2(π/5) - 2

f(π/5) = sin(π) - 2π/5 - 2

f(π/5) = 0 - 2π/5 - 2

f(π/5) = - 2π/5 - 2

f(π/5) = (- 2π - 10)/10

f(π/5) = - 2(π + 10)/10

f(π/5) = - 2(π + 10)/5

f(π/5) = - 2(π + 10)/5

f(π/5) = - 2(3.142 + 10)/5

f(π/5) = - 2(13.142)/5

f(π/5) = - 26.284/5

f(π/5) = -5.2568

Both circles have the same center. The circumference of the inner circle is 18.84 feet. What is the area of the shaded region?

Answers

The area of the shaded region is  π(R + 3)² - 9π where R is teh radius of the outer circle

Calculating the area of the shaded region

The circumference of the inner circle is 18.84 feet

So, we have

2πr = 18.84

Divide by 2π

r = 18.84/2π

Evaluate

r = 3.0

So, the area of the inner circle is

A = πr²

This gives

A = π * 3²

Evaluate

A = 9π

The shaded area is

Area of big - Area of inner circle

So, we have

Shaded area = π(R + 3)² - 9π where R is teh radius of the outer circle

A data set contains three points, and two of the residuals are-7 and 4. What is the third residual?
A. 7
B. -3
C. -4
D. 3

Answers

Answer:

D

Step-by-step explanation:

We know that the residual is the difference between the observed value and the predicted value for a given point. Let's assume that the predicted values for the three points in the data set are denoted by ŷ₁, ŷ₂, and ŷ₃, and the observed values are denoted by y₁, y₂, and y₃.

We can write the residuals as:

e₁ = y₁ - ŷ₁

e₂ = y₂ - ŷ₂

e₃ = y₃ - ŷ₃

We are given that two of the residuals are -7 and 4.
Let's assume that e₁ = -7 and e₂ = 4.

We can use these values to find the third residual e₃.Since the sum of residuals is always equal to zero, we have:

e₁ + e₂ + e₃ = 0

Substituting the values of e₁ and e₂, we get

:-7 + 4 + e₃ = 0

Simplifying, we get:

e₃ = 3

Therefore, the third residual is 3, which is option D.

The expected number of hits

= [tex]\sum xP(X=x) = 0.96[/tex]

How to solve

Let X be a Binomial random variable that denotes the number of hits

where the parameters are n = 3, p = 0.320

P(X = x) = [tex]\binom{3}{x}*0.32^{x}*0.68^{3-x} , x = 0,1,2,3[/tex]

(a) The probability distribution of X is

P(X = 0) = 0.3144

P(X = 1) = 0.4439

P(X = 2) = 0.2089

P(X = 3) = 0.0328

X 0 1 2 3

P(X = x) 0.3144 0.4439

Answers

The parabola for the expression are given in attachment.

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line, which is known as the directrix

y=2x(x-7)

Let us take few values of x and y and draw the parabola

Similarly we draw the graph for (x+4)(x-4)
