Multiple Choice
What data are represented by the stem-and-leaf plot below?
Three rows of numbers are shown.
The key shows that 4 vertical line 1 means 41.
Row 1 is 3 vertical line 7 8 9
Row 2 is 4 vertical line 1 3 7
Row 3 is 5 vertical line 2 4
A. 37, 38, 39, 41, 43, 47, 52, 54
B. 73, 83, 93, 14, 34, 74, 25, 45
C. 7, 8, 9, 1, 3, 7, 2, 4
D. 37, 38, 39, 14, 34, 74, 25, 45
The correct answer is A. 37, 38, 39, 41, 43, 47, 52, 54 are the data represented by the stem-and-leaf plot.
To determine the data represented by the stem-and-leaf plot, we need to interpret the information given.
In the stem-and-leaf plot:
- The largest digits of each number form the "stem," while the smallest digit represents the "leaf."
- The key states that a stem value of 4 with a leaf value of 1 means 41.
Looking at the rows:
- Row 1 is 3 with leaves of 7, 8, and 9. This translates to 37, 38, and 39.
- Row 2 is 4 with leaves of 1, 3, and 7. This translates to 41, 43, and 47.
- Row 3 is 5 with leaves of 2 and 4. This translates to 52 and 54.
Based on this interpretation, we can conclude that the data represented by the stem-and-leaf plot is:
A. 37, 38, 39, 41, 43, 47, 52, 54
The stem-and-leaf plot shown has three rows of numbers. The key indicates that 4 vertical line 1 corresponds to the number 41.
Looking at the rows individually:
- Row 1: 3 vertical line 7 8 9 translates to the numbers 37, 38, 39
- Row 2: 4 vertical line 1 3 7 translates to the numbers 41, 43, 47
- Row 3: 5 vertical line 2 4 translates to the numbers 52, 54
Combining all the numbers from the rows, we get:
37, 38, 39, 41, 43, 47, 52, 54
Therefore, the correct option is:
A. 37, 38, 39, 41, 43, 47, 52, 54
