To interpret the stem-and-leaf plot, the "stem" represents the tens place, and the "leaf" represents the ones place.
Here's the breakdown of the values represented in the stem-and-leaf plot:
- Stem 1: 15, 19
- Stem 2: 22, 23, 27, 28
- Stem 3: 35
- Stem 4: 40, 41, 44, 45, 40, 47, 50, 54
From this breakdown, we can see the following values represented by the stem-and-leaf plot:
- 15
- 19
- 22
- 23
- 27
- 28
- 35
- 40
- 41
- 44
- 45
- 47
Among the values in the responses you provided (10, 10, 21, 21, 44, 44, 51), the value 44 is present in the data set.
So, the answer is 44.
