Question

this shows how many baseball cards a group of friends have in their collections. how many friends have baseball card collections with more than 70 cards?

Explanation:

Step1: Identify data in stem - and - leaf plot

The stem - and - leaf plot has stems 6, 7, 8, 9, 10. We need to count the number of leaves for stems 7, 8, 9, 10 since we want collections with more than 70 cards.

Step2: Count leaves for relevant stems

For stem 7, the leaves are 2, 2, 5, 8 (4 leaves). For stem 8, the leaves are 1, 4, 8 (3 leaves). For stem 9, there are no leaves shown (0 leaves). For stem 10, the leaf is 0 (1 leaf).

Step3: Sum up the counts

4 + 3+0 + 1=8.

Answer:

8
