The graph of an equation has a minimum y value of 12. This minimum occurs at an x value of 3. What is true of the graph of the equation? А
If x is less than 3, then y is less than 12.
B
If x is less than 3, then y increases as x increases
с
if x is greater than 3, then y decreases as x increases
D
If x is greater than 3, then y increases as x increases

Assume that females have pulse rates that are normally distributed with a mean of mu equals 72.0 beats per minute and a standard deviation of sigma equals 12.5 beats per minute. complete parts (a) through (c) below. a. if 1 adult female is randomly selected, find the probability that her pulse rate is between 65 beats per minute and 79 beats per minute. the probability is? b. if 16 adult females are randomly selected, find the probability that they have pulse rates with a mean between 65 beats per minute and 79 beats per minute. the probability is? c. why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
