Lots of ! matthew determined the average number of green candies in a sample set of 10 bags of candies. the results of the last 5 samples of 10 bags are shown. what does the variance tell you about making predictions from one of the samples? picture included.

The numbers have no pattern, so there is no easy way to predict the number of candies

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
