Answer:

$253

Step-by-step explanation:

Margin of error is the critical value times the standard error.

MoE = z × σ/√n

At 99% confidence, z = 2.576.

MoE = 2.576 × 844/√74

MoE = 253

Which rule best describes the following pattern?
Oksanka [162]

Answer:

Add I, add 9, repeat.

Step-by-step explanation:

It is because if you look at the Add 9 subtract 8, repeat. it won't work

If you look at add 10, subtract 9, repeat. it its just like the first one, it won't work.

If you look at add 1, add 10, repeat, it also won't work from when you are getting 6 to 15.

So if you look at Add I, add 9, repeat., it works for all.

<h2>Answer: </h2><h2>3.19</h2><h2>______________________________________</h2><h3>Honey, all you need to do is multiply.</h3><h3>−2.75 by −1.16</h3><h2>______________________________________</h2>

Answer and step-by-step explanation:

Tim Carter money made:

First 40 hours = 40 * pay per hour = 40 * 5.15 = $206 (weekly pay)

Because he works for 50 hours so next 10 hours (50-40) = 10 * (1.5*5.15)

= 10* 7.725 = $77.25

Total money he made:

= 206 + 77.25 = $283.25

Jeese Jones money amde:

First 40 hours = 40 * pay per hour = 40 * 5.15 = $206 (weekly pay)

Because he works for 47.5 hours so next 7.5 hours (47.5-40) = 7.5 * (1.5*5.15)

= 7.5 *7.725 = $57.9375

Total money Jeese Jones made:

= 206 + 57.9375 = $263.9375

Barbara Burns money made:

First 40 hours = 40 * pay per hour = 40 * 5.15 = $206 (weekly pay)

Because Barbara Burns works for 44 hours so next 4 hours (44-40) = 4 * (1.5*5.15)

= 4* 7.725 = $30.9

Total money Barbara Burns made:

= 206 + 30.9 = $236.9

Hope this help you :3
