The number of students in each
homeroom class in Jim’s school is
shown in the stem-and-leaf plot below.

Each Homeroom Class
1 7 8 8 9 9
2 0 2 3 4 5 8 8 8
3 2 3 4 7
To determine the number of students in each homeroom class, we can use the stem-and-leaf plot provided.
In a stem-and-leaf plot, the "stem" represents the tens digit of the numbers, while the "leaves" represent the ones digit. The numbers are organized in ascending order within each stem.
Looking at the plot, we can see that there are three stems: 1, 2, and 3.
For the stem 1, we have leaf 7, 8, and 9. This represents the numbers 17, 18, and 19. Therefore, there are 3 students in the homeroom class with 1 as the tens digit.
For the stem 2, we have leaf 0, 2, 3, 4, 5, and 8. This represents the numbers 20, 22, 23, 24, 25, and 28. Therefore, there are 6 students in the homeroom class with 2 as the tens digit.
For the stem 3, we have leaf 2, 3, 4, and 7. This represents the numbers 32, 33, 34, and 37. Therefore, there are 4 students in the homeroom class with 3 as the tens digit.
So, the number of students in each homeroom class is:
- 1: 3 students
- 2: 6 students
- 3: 4 students
