The end result will not be the same as the beginning number because of the change in amounts in-between. Here's an example similar but easier

I get half of it more

I now have three dollars

I give half of that away

Now I have a dollar and a half

It all depends on that the course if of the numbers

How many weeks of data must be randomly sampled to estimate the mean weekly sales of a new line of athletic footwear? We want 98

Irina18 [472]

Answer:

$n=(\frac{2.33(1400)}{400})^2 =66.50 \approx 67$

So the answer for this case would be n=67 rounded up

Step-by-step explanation:

Information given

$\bar X$ represent the sample mean for the sample

$\mu$ population mean

$\sigma=1400$ represent the sample standard deviation

n represent the sample size

Solution to the problem

The margin of error is given by this formula:

$ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$ (a)

And on this case we have that ME =400 and we are interested in order to find the value of n, if we solve n from equation (a) we got:

$n=(\frac{z_{\alpha/2} \sigma}{ME})^2$ (b)

The critical value for 98% of confidence interval now can be founded using the normal distribution. And the critical value would be $z_{\alpha/2}=2.33$ , replacing into formula (b) we got:

$n=(\frac{2.33(1400)}{400})^2 =66.50 \approx 67$

So the answer for this case would be n=67 rounded up

Match the expression to its simplified form.

omeli [17]

Answer:

Step-by-step explanation:

5³ = 5 × 5 × 5 = 125

$2^{5}$ = 2 × 2 × 2 × 2 × 2 = 32

$5^{-2}$ = $\frac{1}{5^{2} }$ = $\frac{1}{25}$

$2^{-4}$ = $\frac{1}{2^4}$ = $\frac{1}{16}$

A company paid $48 for 2 cases of printer paper. Each case contained 12 packages of paper. Next month the company’s office manag

il63 [147K]

Since 2 cases = $48

÷ 48 by 2 to get the cost of one case of paper

48÷2=$24 per case
and each case has 12 pack of paper

so $24 for 12 packs of paper

180÷12=15, which gives you the number of case you need

15 cases × $24= $360 for 180 packs
