The heights (in inches) for a sample of 23 male adults are 62.82, 79, 76, 73, 70, 67, 64, 61, 80, 79, 75, 72, 74, 74, 74, 75, 75, 72, 72, 68, 68,

Draw the histogram for these data using an initial class boundary of 60.5 and a class width of 5. Note that you can add or remove classes from the figure. Label
each dass with its endpoints.

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
