Find the average rate of change of the function over the given intervals. f(x) = 9x3 + 9; [6,8], [-1,1] the average rate of change of the function f(x) = 9x3 + 9 over the interval [6,8] is (simplify your answer.) the average rate of change of the function f(x) = 9x3 + 9 over the interval [-1,1] is (simplify your answer.)

Sam is picking fruit from a basket that contains many different kinds of fruit. which set of events is independent?

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
