Using the function f(x) = 2x + 7 find the following: (show your work) 1. f(x) = 13 2. f(x)=21 to use function notation we either replace the x in the equation or the f(x) in the equation. to find f(2) we replace the in the equation with and then solve for f(x). to find f(x)=2 we replace the in the equation with and then solve for x.

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.
