greta collects the number of miles run each week from random sample of female marathon runners. her data are shown below. she ma

dedylja [7]

Her statement is not reasonable because it is not true that 25% of female marathoners run 13 or more miles a week, it is true that 25% run less than 13 miles a week (out of the data). The rest of the data would be 75%, making the statement, "75% of female marathoners run 13 or more miles a week" true. The way she recorded the data does not interfere with the statement being reasonable since it is unbiased.

What is the equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (−2, 4)?

GrogVix [38]

First find the slope of the given line like this:
$5x + 2y = 12\\2y=-5x+12\\y=\frac{-5}{2}x+6$
If two lines are parallel, then they have the same slope, so the equation we are looking for is in the form:
$y=\frac{-5}{2}x+a$ and we have to find b using the given point like this:
Substitute x = -2 and y=4 in the above equation like this and solve for a:
$4=\frac{-5}{2}(-2)+a$
$4=5+a$
$a=4-5=-1$
The equation of the line is then the following:
$y=\frac{-5}{2}x-1.$
