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!

In the solution of the equation 5 + 3x = -2x + 9, 2x is added to the equation first. Which of the following should be done next?
puteri [66]

You should subtract 5 from both sides next.


Adding 2x to both side will give you the following.


5 + 5x = 9


And since you got all the variable terms to the left, you want all the constant terms to the right. You do that by subtracting 5 from both sides. This gives you the below statement.


5x = 4


You can then divide to solve.


x = 4/5 or .8
