1. A random sample of 28 professionals in a large city were surveyed about the length of their daily commute. The data (in minutes) is shown below.
20 35 42 52 65 20 60
22 20 41 25 28 27 50
49 24 37 23 24 32 44
47 58 30 32 48 55 58
a) Find the mean of the sample
b) Find the standard deviation of the sample
c) Find the five-number summary for the sample

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
