You have five dice, like in a game of Yahtzee! Suppose you roll the five dice once and sum the numbers the five dice show. 1. What is the mean and the standard deviation of the sum of five dice?

2. Suppose you average 60 of such rolls with the five dice. What is the distribution of this average?

3. What is the chance the average of 60 such rolls is larger than 18?

Zroms according to the synthetic division below, which of the following statements are true? check all that apply. 352 -2 6 -12 12 2 4 0 i a. (x-3) is a factor of 2x2 - 2x - 12. b. the number 3 is a root of f(x) = 2x2 - 2x - 12. c. (2x2 - 2x - 12) = (x + 3) = (2x + 4) d. (2x2 - 2x-12) - (x-3) = (2x + 4) e. (x+3) is a factor of 2x2 - 2x - 12. o f. the number -3 is a root of fx) = 2x2 - 2x - 12. previous
