Find the residual values, and use the graphing calculator tool to make a residual plot.
(sorry the picture is bad)

does the residual plot show that the line of best fit is appropriate for the data?
a.) yes, because the points have no clear pattern.
b.) no, the points have no pattern.
c.) no, the points are in a linear pattern.
d.) yes, the points are in a curved pattern.

please try to hurry!!

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

answer: 40.95
