Answer:

jacket 80

shoes 32 and 16

shirt 9   , 8.04,   4.08

Step-by-step explanation:

you need to multiply the original cost by the percentage off and then subtract from the original

example

Jacket is originally priced at $120 it is on sale for 1/3 off which means that if you divide 120 by 3 you will get 40.  but you would have to subtract the 40 from 120 giving you 80

As described in z-distribution the answers are given below:

a) The 95% confidence interval estimate for the population mean spending by a customer on visiting salon per month is given as follows: (747, 853).

b) The sampling error at 95% confidence level is of: $35.78.

What is a z-distribution ?

The normal distribution with a mean of 0 and a standard deviation of 1 is referred to as the standard normal distribution (also known as the Z distribution) (the green curves in the plots to the right). It is frequently referred to as the bell curve since the probability density graph resembles a bell.

solution:

The bounds of the confidence interval are given as follows:

In which:

is the sample mean.

z is the critical value.

n is the sample size. is the standard deviation for the population.

The parameters for this problem are given as follows:

Hence the lower bound of the interval is of:

800 - 200 x 1.96/square root of 55  = 747.

The upper bound of the interval is of:

800 + 200 x 1.96/square root of 55  = 853.

The sampling error for a sample size of 120 is calculated as follows:

200 x 1.96/square root of 120 = $35.78.

Write 0.7 as a percent (the 7 has a line on top of it) . round to the nearest percent
Bingel [31]
I'm pretty sure the answer is C. 78%. (KEEP READING)
 
Because you move the decimal over to the right two times and get 70 add a percent to the end and get 70%.       _ 
But since it is repeating it would be 77%

So if you are rounding it to the nearest number, to ones, then the answer is C. But if you are rounding to the tens then it would be D.

I personally would put C because you want the "nearest percent".
