Express The Formula In Terms Of The Height, Use That Formula To Find The Height When The Volume Is And

Answers

Answer 1

The formula to find the height of the Cylinder is; h = V/(πr²) and at V = 45π and r = 3, we have; h = 5

How to change the subject of the formula?

We are given the formula for volume of a cylinder as;

V = πr²h

where;

h is height

r is radius

To make h the subject, let us divide both sides by  πr² to get;

V/(πr²) = h

At V = 45π and r = 3, we have;

h = 45π/(πr²)

h = 45/3²

h = 5

bank pays 0.250% compounded monthly, how much will her money be at the end of years?​

Answers

Answer:

200.4 at 0.25%

Step-by-step explanation:

Given data

P= P200

r= 0.25%

t= 1 year

n= 12

A= P(1+ r/n)^nt

substitute

A= 200(1+ 0.0025/12)^12*1

A= 200(1+ 0.00020833333)^12

A= 200(1.0002)^12

A= 200* 1.002

A= 200.4

Hence the amount is 200.4 at 0.25%

63 = 3 * 3 * 7

Seventy-five percent of the light aircraft that disappear while in flight in a certain country are subsequently discovered. Of the aircraft that are discovered, 70% have an emergency locator, whereas 89% of the aircraft not discovered do not have such a locator. Suppose a light aircraft has disappeared. (Round your answers to three decimal places.) (a) If it has an emergency locator, what is the probability that it will not be discovered

Answers

Answer:

0.05 = 5% probability that it will not be discovered

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Has an emergency locator

Event B: Not discovered

Probability of having an emergency locator:

70% of 75%(discovered).

100 - 89 = 11% of 100 - 75 = 25%(not discovered). So

[tex]P(A) = 0.7*0.75 + 0.11*0.25 = 0.5525[/tex]

Intersection of events A and B

Having an emergency locator and not discovered, so 11% of 25%

[tex]P(A \cap B) = 0.11*0.25 = 0.0275[/tex]

What is the probability that it will not be discovered?

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0275}{0.5525} = 0.05[/tex]

0.05 = 5% probability that it will not be discovered

One number is 24 more than the other. What are the numbers if their sum is 84

Answers

Answer:

The required numbers are 30 and 54.

Step-by-step explanation:

Let 'x' be the smaller numberLet 'y' be the larger number

Given that one number is 24 more than the other, so

[tex]y = x + 24[/tex]

Given that the sum of the numbers is 84, so

[tex]x + y = 84[/tex]

so we have two equations

[tex]\begin{bmatrix}y=x+24\\ x+y=84\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}y-x=24\\ y+x=84\end{bmatrix}[/tex]

subtracting the equartions

[tex]y+x=84[/tex]

[tex]-[/tex]

[tex]\underline{y-x=24}[/tex]

[tex]2x=60[/tex]

now solve 2x = 60 for x

[tex]2x=60[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}=\frac{60}{2}[/tex]

Simplify

[tex]x=30[/tex]

For y - x = 24 plug in x = 30

[tex]y-30=24[/tex]

Add 30 to both sides

[tex]y-30+30=24+30[/tex]

Simplify

[tex]y=54[/tex]

Thus, the required numbers are 30 and 54.

Verification:

Given that one number is 24 more than the other, so

[tex]y = x + 24[/tex]

substitute x = 30

y = 30 + 24

y = 54

Thus, y is 24 more than x.

Given that the sum of the numbers is 84, so

[tex]x + y = 84[/tex]

sustitute x = 30 and y = 54

30 + 54 = 84

84 = 84

L.H.S = R.H.S

Thus,  the sum of the numbers is indeed 84.

The inequality shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥  

The inequality that represents the given statement is

(1/4)n ≤ 95 + 9

The number n is n ≤ 416.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥  

We have,

Nine less than the product of a number n and 1/4 is no more than 95.

Let the number be n.

Now,

No more than means,

We have less than, greater than, and equal to.

We can use less than and equal to.

The inequality can be written as,

1/4 x n - 9 ≤ 95

(1/4)n - 9 ≤ 95

Add 9 on both sides.

(1/4)n ≤ 95 + 9

(1/4)n ≤ 104

Multiply 4 on both sides.

n ≤ 416

Thus,

The inequality that represents the given statement is

(1/4)n ≤ 95 + 9

The number n is n ≤ 416.

Step-by-step explanation:

A recent study was conducted in which a random sample of men and a random sample of women were surveyed about whether they were fans of a professional football team. The study found that 39 percent of men in the sample were fans and 22 percent of women in the sample were fans. A 99 percent confidence interval for the difference in the proportion of fans of a professional football team between men and women was reported as (0.133,0.207) . Which of the following statements is the best interpretation of the interval?

a. The difference in the percents of fans of a professional football team between men and women is 17%.
b. There is a 99% chance of finding a difference between 13.3% and 20.7% for the percents of men and women who are fans of a professional football team.
c. We are 99% confident that the percent of men who are fans of a professional football team exceeds that of women by at least 20.7%.
d. We are 99% confident that the difference in the sample percents of men and women who are fans of a professional football team is between 13.3% and 20.7%.
e. We are 99% confident that the difference in the population percents of all men and women who are fans of a professional football team is between 13.3% and 20.7%.

Answers

Answer:

e. We are 99% confident that the difference in the population percents of all men and women who are fans of a professional football team is between 13.3% and 20.7%.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

In this question:

99% confidence interval for the difference  in the proportion of fans of a professional football team between men and women is of (0.133, 0.207)

The interpretation is that we are 99% sure that the true proportion is in this interval for the entire population, so the correct answer is given by option e.
