Oy- (11
y (11)
(18)(5)
oy-
5
11
2 y = (1865

Answers

Answer:

y = 18/5(11)

Step-by-step explanation:

If y varies directly as x, this is expressed as;

y∝x

y = kx

k is the constant of proportional constant

if y = 18 and x = 5

18 = 5k

k = 18/5

to get the expression that can be used to find the value of y when x is 11

y = kx

y = 18/5(11)

This gives the required expression

Staples sells boxes of pens for ($10) and rubber bands for ($24). Leona ordered a total of 24 cartons for $210. How many boxes of each did Leona order? Hint: Let P = Pens.

Answers

Answer:

Leona ordered 19 boxes of pens and 5 rubber bands

Step-by-step explanation:

Let there are p pen and b rubber bands.

ATQ,

p+b = 24 ...(1)

and

10p+4b = 210 ...(2)

Multiply equation (1) by 10.

10p+10b = 240 ...(3)

Subtract equation (2) from (3).

10p+10b-(10p+4b ) = 240-210

6b = 30

b = 5

Put the value of b in equation (1).

p+5 = 24

p = 19

Hence, Leona ordered 19 boxes of pens and 5 rubber bands.

Annual sales for a company are $155,000 and increases at a rate if 8% per year for 9 years

Answers

8% of 155,000 = 12,400
155,000 + 12,400 = 167,400

- this is the rate for one year, find 8% of 167,400 and use addition to add your answer to 167,400 find the cost of the 2nd year, keep doing this until you have reached 9 years

The value of annual sales in 9 years is  $309,845.72.

What is the value of annual sales in 9 years?

In order to determine the annual sales of the company in 9 years, the formula to be used is:

FV = P (1 + r)^n

Where:

FV = Future value P = Present value R = interest rate N = number of years

$155,000 x (1.08)^9 = $309,845.72

Researchers were investigating whether there is a significant difference between two medications, R and S, designed to reduce fleas found on cats. From a sample of 300 cat owners, the researchers randomly assigned 150 cat owners to use medication R on their cats and the remaining cat owners to use medication S. For the cats using medication R, 88 percent had no fleas. For the cats using medication S, 90 percent had no fleas. Which of the following is the most appropriate method for analyzing the results?

A two-sample z -test for a difference in population proportions

A two-sample z-test for a difference in sample proportions

A one-sample z-test for a sample proportion

A one-sample z-test for a population proportion

A one-sample z-test for a difference in sample proportions

Answers

Answer:

A) A two-sample  z -test for a difference in population proportions

Step-by-step explanation:

To determine whether a difference in proportions is significant, the two-sample z-test for a difference in population proportions is the most appropriate method for the analysis.

The most appropriate method for analyzing the results is A. A two-sample z-test for a difference in population proportions.

What is the hypothesis?

In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter.

In this scenario, we have two different treatments (medication R and S) applied to two separate samples (150 cat owners each) and we want to determine if there is a significant difference in the proportion of cats with no fleas between the two groups.

This is a classic scenario for a two-sample z-test for a difference in population proportions, which tests the hypothesis that the difference in proportions between two independent populations is equal to zero.

Thus, a two-sample z-test for a difference in population proportions.

Hence, the correct answer would be option (A)
