URGENT Choose the true statement(s):

I. r^2 represents the proportion of variation in the y-variable that is explained by the x-variable.

II. A correlation coefficient of −0.9 indicates a weak negative association between x and y.

III. A correlation coefficient of 0.5 means that 50% of the variation in the y-values is explained by the x-values.

IV. When r = 1, there is a perfect cause-and-effect relationship between the x-variable and the y-variable.

A) I only
B) I and II only
C) I, III, and IV only
D) III and IV only

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
