Answer 2

The stem-and-leaf plot below shows the total number of points different gymnasts earned in a gymnastics competition. How many gymnasts scored less than 50 points?

Stem Leaf
6 1 2 2 6
5 1 4 6 8 9
4 1 2 2 7 8 9
3 6 9
A. 4
B. 6
C. 7
D. 8

Answer 3

The answer is C. 7.

To find the number of gymnasts who scored less than 50 points, we need to look at the stem-and-leaf plot and count the number of leaves that are less than 5 (since the stems represent tens).

We see that there are 4 leaves in the 40s, 3 leaves in the 30s, and 0 leaves in the 20s, for a total of 7 gymnasts who scored less than 50 points.

Answer 5

The answer is B. Mrs. James’s class, one; Mr. Cleveland’s class, two.

To determine the number of students who scored an 85 in each class, we need to look at the leaf corresponding to the stem of 8.

Mrs. James’s class has one leaf for 85.

Mr. Cleveland’s class has two leaves for 85.

Therefore, the answer is Mrs. James’s class, one; Mr. Cleveland’s class, two.
