Use the image to answer the question.
An illustration shows four rows of data. A vertical line is drawn after the first digit from the left, thereby splitting the rows into a two-column table. The data are as follows: The first row shows digit 5 in the first column and digits 3 5 5 in the second column. The second row shows digit 4 in the first column and digits 0 0 0 1 4 6 in the second column. The third row shows digit 3 in the first column and digits 7 7 8 8 9 in the second column. The fourth row shows digit 2 in the first column and digits 1 3 4 5 in the second column.

Answer 1

To find the number that appears most frequently in the stem-and-leaf plot, we need to extract the numbers represented in the plot.

The stem-and-leaf plot provided can be interpreted as follows:

- The first row (stem 5): 5 | 3 5 5 → represents the numbers 53, 55, 55
- The second row (stem 4): 4 | 0 0 0 1 4 6 → represents the numbers 40, 40, 40, 41, 44, 46
- The third row (stem 3): 3 | 7 7 8 8 9 → represents the numbers 37, 37, 38, 38, 39
- The fourth row (stem 2): 2 | 1 3 4 5 → represents the numbers 21, 23, 24, 25

Now we can count the frequency of each number:
- **53**: 1 time
- **55**: 2 times
- **40**: 3 times
- **41**: 1 time
- **44**: 1 time
- **46**: 1 time
- **37**: 2 times
- **38**: 2 times
- **39**: 1 time
- **21**: 1 time
- **23**: 1 time
- **24**: 1 time
- **25**: 1 time

In summary:
- 53 appears 1 time
- 55 appears 2 times
- 40 appears 3 times
- 41 appears 1 time
- 44 appears 1 time
- 46 appears 1 time
- 37 appears 2 times
- 38 appears 2 times
- 39 appears 1 time
- 21 appears 1 time
- 23 appears 1 time
- 24 appears 1 time
- 25 appears 1 time

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

So, the answer is:

**40**
