3 7 7 8 8 9
2 1 3 4 5
Which number appears most frequently in the dataset shown in this stem and leaf plot?
A. 88
B. 40
C. 55
D. 77

Answer 1

To determine which number appears most frequently in the stem and leaf plot, we can first extract the numbers represented by the stems and leaves.

- Stem 5: 53, 55, 55
- Stem 4: 40, 40, 40, 41, 44, 46
- Stem 3: 37, 37, 38, 38, 39
- Stem 2: 21, 23, 24, 25

Now let's count the frequency of each number:

- 53 appears once.
- 55 appears twice.
- 40 appears three times.
- 41 appears once.
- 44 appears once.
- 46 appears once.
- 37 appears twice.
- 38 appears twice.
- 39 appears once.
- 21 appears once.
- 23 appears once.
- 24 appears once.
- 25 appears once.

Now, let's summarize the counts:

- 53: 1
- 55: 2
- 40: 3
- 41: 1
- 44: 1
- 46: 1
- 37: 2
- 38: 2
- 39: 1
- 21: 1
- 23: 1
- 24: 1
- 25: 1

Thus, the number that appears most frequently is **40**, which appears 3 times.

The answer is **B. 40**.
