T/9
you divide the number of cars, t, by the number of packages it came in, 9
That is the simplest form
8, 11, 12, 13, 16, 42
Add together and divide by 6 to get the mean.
102/6 = 17
Find the middle of the data for the median.
(12 + 13)/2 = 12.5
The mean is 17, the median is 12.5, and the mean is more affected by the outlier. 17 (the mean) is not a good measure of center.
Y=-1/3-2 because you have to make the slope into a negative inverse and the y-intercept stays the same because it's perpendicular.
Normal:3
Negative inverse: -1/3
