Final answer:
The given stem and leaf plot represents the ages 20, 30, 40, 50, 60, 70, 80.
Step-by-step explanation:
To determine the list of ages represented by the given stem and leaf plot, we need to read the stems and their corresponding leaves. The stems represent the tens digit, while the leaves represent the ones digit. Reading from left to right, the stems are: 2, 3, 4, 5, 6, 7, and 8. The leaves are: 6, 5, 0, 3, 5, 7, 9, 4, and 9. Combining the stems and leaves, we get the ages: 26, 35, 40, 43, 45, 47, 49, 54, 59, 69, 79, 86, and 89. Therefore, the given stem and leaf plot represents the ages 20, 30, 40, 50, 60, 70, 80.
