Yo can someone help me please with math

First you need to know what a range in a data set is and ythe range is the difference between the highest and lowest values within a set of numbers. To calculate range, subtract the smallest number from the largest number in the set. If a six-server rack includes 90 W, 98 W, 100 W, 102 W, 105 W and 110 W, the power consumption range is 110 W - 90 W = 20 W.

1. 5, 7, 8, 10, 11, 13, 14, 18, 27 so then do 27-5 to get 22 as your answer

2. 8

3. 16

I hope that this helpes you :)

What is the range of this data set?

27, 5, 11, 13, 10, 8, 14, 18, 7

22

Use the list below to find the lower quartile.

27, 5, 11, 13, 10, 8, 14, 18, 7

7.5

Use the list below to find the upper quartile.

27, 5, 11, 13, 10, 8, 14, 18, 7

16

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12

y=mx+b is the final answer!   : )
