On average the data points lie between what points from the mean for the following data 8,9,12,12,13,13,13,15,16,16,16,17,1 7,18,18,18,18,18,20,20

15.35

Step-by-step explanation:

8+9+12+12+13+13+13+15+16+16+16+17+17+18+18+18+18+18+20+20=397

307/20=15.35

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
