It means it has no rise or run it means it’s 0 on the plot
The range is the difference in between the largest and the smallest number in the set.
On a box and whisker plot, the maximum and the minimum are shown as the dots on the furthest right and left side. On this particular one, they would be the dots on 29 and 17.
All you have to do is
29-17
and you get 12
The range of the data is 12.
Hope this helps!
This looks like it has something to do with a scale. flip the other shape upside down and the two figures are the same shape, just different size. so the 75 and 40 are on top, 1.875 times greater than 40, so then do 32 x 1.875 to get 60.
