Hailey made a mistake and forgot to return her library books on time! She had to pay a late fee of $1.08 per day. She returned t

he books 8 days late. Once she realized that she had to pay a late fee she decided that she was going to pay ¼ of the fee every time she got to the library. How much did she pay per day until she paid the whole late fee off?

Answer:

$1.08 per day times 8 days.

$1.08 x 8 = $8.64 owed

Hailey is only paying 1/4. When talking about money, 1/4 = $0.25.

$8.64 x $0.25 = $2.16

OR

You can calculate as $8.64 x 1/4 and get $2.16

nikitadnepr [17]

Answer:

Zac Made 28 Jackets

I eventually got to the point where i found that Tyra made 20 jackets and Zac made 28 making up to 48 jackets in total.

Find the margin of error for a 90% confidence interval when the standard deviation is LaTeX: \sigma= 50????=50 and LaTeX: n = 25
Murrr4er [49]

Answer:

The margin of error  for a 90% confidence interval is 16.4

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 25

Standard deviation = 50

z_{critical}\text{ at}~\alpha_{0.10} = \pm 1.64

Margin of error =

z_{critical}\times \dfrac{\sigma}{\sqrt{n}}

Putting the values, we get,

1.64\times \dfrac{50}{\sqrt{25}} = 16.4

Thus, the margin of error  for a 90% confidence interval is 16.4
