Afilm set designer is using white and colored tiles in a pattern to create paths of different lengths. if x is the length of the path in feet, the number of colored tiles needed to make it is calculated using the rule

(8x2y2)(3xy)

where y represents the number of white tiles.

which simplified expression represents the number of colored tiles used for a path of length x feet?
• 24x3y3
• 11x3y3
• 24x2y2
• 11x2y2

1. suppose that scores on a knowledge test are normally distributed with a mean of 71 and a standard deviation of 6. a. label the curve: show the mean and the value at each standard deviation: b. if angelica scored a 76 on the test, what is her z-score? (draw her score on the curve above and label) c. what percent of students did angelica score higher than? how can you tell? d. if 185 students took the test, how many students scored higher than angelica?
