What data are represented by the stem-and-leaf plot below?
stem-and-leaf plot
3| 7 8 9
4| 1 3 7
5| 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
it is A since the the number to the left of the line is the tens digit
so 37, 38, 39
41, 43, 47
52, 54
To determine the data represented by the given stem-and-leaf plot, we need to understand how the plot is constructed. In a stem-and-leaf plot, the digits on the left are known as the "stem," while the digits on the right are known as the "leaves."
Looking at the stem-and-leaf plot:
3| 7 8 9
4| 1 3 7
5| 2 4
The stem values are 3, 4, and 5, while the leaf values are 7, 8, 9, 1, 3, 7, 2, and 4. To find the complete data, we combine the stem and leaf values.
Combining the stem and leaf values, we get the following data:
37, 38, 39, 41, 43, 47, 52, 54
Now, let's compare this data with the given answer choices:
A. 37, 38, 39, 41, 43, 47, 52, 54: This matches the data represented by the stem-and-leaf plot.
B. 73, 83, 93, 14, 34, 74, 25, 45: The stem-and-leaf plot does not contain these values.
C. 7, 8, 9, 1, 3, 7, 2, 4: This is a mix of both the stem values and leaf values, but we need to combine them.
D. 37, 38, 39, 14, 34, 74, 25, 45: This matches the data represented by the stem-and-leaf plot.
Therefore, the correct answer is option A. The data represented by the stem-and-leaf plot is 37, 38, 39, 41, 43, 47, 52, and 54.
