The height(in ft) of a golf ball hit in the air is given by the equation h(t) = -16t^2 + 128t, where t represents the time in seconds after it was hit. Part A) Find the maximum height reached by the golfball.

Part B) For how many seconds was the golfball in the air? Or how long did it take for the golfball to reach the ground?

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
