4.  When reading the stem and leaf plot the only values that fall between the range of  40 < x <60  is the 4 values of 45.  They are located at the tail end of the 4 stem after the zeros. The 40s and 60s are not counted because it is not mentioned equal to 40 or 60.

The correct answer is:

4.

Explanation:

The number 40 is written in this stem-and-leaf plot as 4|0.  60 is written as 6|0.  There are 4 leaves between these numbers; 5, 5, 5 and 5, with the stem of 4.  This means the numbers are 45, 45, 45 and 45.  There are only 4 between these two numbers.
