The answer is A
Based on the stem-and-leaf plot provided, the data represented are:
Row 1: 37, 38, 39
Row 2: 14, 34, 74
Row 3: 25, 45
Therefore, the correct answer is:
D. 37, 38, 39, 14, 34, 74, 25, 45
To determine which data is represented by the stem-and-leaf plot, we need to interpret the numbers in each row.
According to the stem-and-leaf plot, the key shows that "4 vertical line 1" means 41. This means that the stem (the leftmost digit) is 4, and the leaf (the rightmost digit) is 1.
Looking at the rows:
- Row 1 is "3 vertical line 7 8 9". This means that the stem is 3, and the leaves are 7, 8, 9.
- Row 2 is "4 vertical line 1 3 7". This means that the stem is 4, and the leaves are 1, 3, 7.
- Row 3 is "5 vertical line 2 4". This means that the stem is 5, and the leaves are 2, 4.
Combining the stems and leaves, we have the following numbers:
37, 38, 39, 41, 43, 47, 52, 54.
Therefore, the correct choice is:
A. 37, 38, 39, 41, 43, 47, 52, 54
