stem | leaf

1 | 3 4 5 6 7
2 | 1 4 4 7 8
3 | 0 5
key: 1|3 = 13 points
in how many games did the team score more than 20 points?

Explanation:

Step1: Understand stem - and - leaf plot

In a stem - and - leaf plot, the stem represents the tens digit and the leaf represents the units digit.

Step2: Identify scores more than 20

For scores more than 20, we consider stems of 2 and 3.
When the stem is 2, the leaves are 1, 4, 4, 7, 8 (5 values). When the stem is 3, the leaves are 0, 5 (2 values).

Step3: Calculate total number

Add the number of values for stem 2 and stem 3. $5 + 2=7$.

Answer:

7
