Let "h" be a function. select all statements that are true for all the functions of "h". a. the function h(a) represents the input of h corresponding to the output a. b. the graph of h is represented by the graph of the equation y=h(x) c. the graph of h shows the value of h(a) for all values of a in the domain. d. if x is any element of the domain of h, then h(x) is an element of the range. e. the function h assigns to each element in the range exactly one element in the domain.

Need now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
