A large toiletry distributor claims that 35% of all individuals who purchase toilet paper from the stores that carry its product

choose original toilet paper, 28% choose sensitive toilet paper, 20% choose ultra-strong toilet paper, and 17% choose ultra-soft toilet paper. To investigate this claim, researchers collected data from a random sample of customers in a large city. The results were 170 packages of original, 105 sensitive, 80 ultra-strong, and 45 ultra-soft toilet paper purchases. Are the data from the sample consistent with the distributor's claim

Answer:

Step-by-step explanation:

Only a few of the data from the sample is consistent with the distributor's claim.

The total of the sample is 400.

From the calculations of proportion from each item in the sample, we have 43%, 26%, 20% and 11%.

This is not exactly consistent with the distributor's claim of 35%, 28%, 20% and 17%.

To further confirm and verify this, a test needs to be carried out and set to a significance level.

You loaned a friend $100 and will charge him 5% annual simple interest when he pay it back
Arturiano [62]

The amount of interest after 3 years will be $15.

The complete question is given below.

You loaned a friend $100 and will charge him 5% annual simple interest when he pay it back. What is the amount of interest after 3 years?

<h3>What is simple interest?</h3>

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

The interest is given as

I = (P × R × T) / 100

Where, P is the initial amount, R is simple interest rate, and T is the time.

We have

P = $100

R = 5%

T = 3 years

Then the interest will be

I = (100 × 5 × 3) / 100

I = $15

More about the simple interest link is given below.

An initial investment of $60.00 increases in value by 15% each year. Which of the following statements are true? Select all that
VikaD [51]
15% each yer
represented by
f(x)=60(1.15^x)

xintercept is when the function equals zero
since it increases only, it cannot equal zero and does not have an x intercept

after 4 years the investment value is 104
after 6 yaers value is 138.7
after 7.86 years the value is179.98 which is roughly 3 times of 60
8 years later183.54 close enough










answers
f(x)=60*1.15^x
after 7.86 years value is 3 times initioal value
after 8 years value is 184
