The sorted data set is ...

1 2 3 3 5 7 8 9

The median is the average of the middle two numbers: (3+5)/2 = 4.

Replacing one of the 3s with a 1 makes the data set be ...

1 1 2 3 5 7 8 9

The average of the middle two numbers is (3+5)/2 = 4.

Write the equation of a line that is perpendicular to the given line and that passes through the given point.

poizon [28]

Answer: y=-3x+29

Step-by-step explanation:

First put in y-intercept form to find the slope

$4x-12y=2\\-12y=-4x+2\\y=\frac{1}{3} x-\frac{1}{6}$

Slope of the 1st equation is 1/3- the slope of the line perpendicular is the opposite reciprocal, so in the case it is -3

Use the point and the new slope to write the new equation in point slope format

$y-y_{1} =m(x-x_{1} )\\y-(-1)=-3(x-10)\\y+1=-3x+30\\y=-3x+29$
