David had test scores of 84, 90, 95, 98, and 88. Find the mean/average of these test scores.
Your answer

91

Step-by-step explanation:

The mean (average) is found by adding all the data and dividing by how many there are. So the mean of 3,3,3 is 3 because 3+3+3=9/3=3

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
