The stemplot below shows the heights (in inches) of students in a class.

5 | 0 1 1 3 6

6 | 2 9

7 | 1 1 3 5 7

Which of the following is a height of a student in the class?

A. 50 inches

B. 72 inches

C. 29 in ches

D. 57 inches

Choice A) 50 inches

Step-by-step explanation:

The stem is the value on the left side of the vertical bar (5, 6, and 7 in that first column). The leaf is a single digit on the right side that pairs up with the stem to form the whole value. In the first row, the stem of 5 pairs up with the 0 to get 50. The next value is 51 because the stem 5 pairs up with the 1 after the 0. Then the value after that is 51 again. Repeated values are allowed.

The entire first row of values is: 50, 51, 51, 53, 56

The second row is: 62, 69

The third row is: 71, 71, 73, 75, 77

We see that only 50 is listed in the four answer choices and no other value.
