4. Find UW if VW= 5/8 in.

The range of ages is found:

D.46

Step-by-step explanation:

Age of college professors is given by a stem and leaf plot such that:

3|  0 2

4|  1 4 4 5

5|  3 5 8 9

6|  2 2 2 5 6 8

7|  5 5 6

Where the numbers on the left side shows the number at 10s place of a certain age, while number on the right side shows that number at Units place. e.g

3|  0 2

It shows ages of:

30 and 32

Range = Largest number in stem and left plot - Smallest number in stem and leaf plot

Range = 76 - 30

Range = 46
