Age Tally Frequency
15-25 Twelve tally marks are shown. 12
26-35 15 tally marks are shown. 15
36-45 8 tally marks 8
46-55 9 tally marks 9
56-65 four tally marks 4
66-75 3 tally marks are shown. 3
76-85 one tally mark 1
Use the table to answer the question.
Which age group of this set of numbers has twice as many people as another age group?
A. 76–85
B. 15–25
C. 36–45
D. 46–55
Well eight = two times four
To determine which age group has twice as many people as another age group, we need to compare the frequencies of each age group.
Looking at the table, we can see that the frequencies are as follows:
- 15-25: 12
- 26-35: 15
- 36-45: 8
- 46-55: 9
- 56-65: 4
- 66-75: 3
- 76-85: 1
To find the age group that has twice as many people as another age group, we can compare the frequencies. We need to find an age group whose frequency is double another age group's frequency.
Comparing the frequencies, we can see that group 15-25 has a frequency of 12, and group 36-45 has a frequency of 8. Group 15-25 has 1.5 times more people than group 36-45, but it is not twice as many.
Comparing the frequencies again, we can see that group 26-35 has a frequency of 15, and group 76-85 has a frequency of 1. Group 26-35 has 15 times more people than group 76-85, which is more than double.
Similarly, comparing the frequencies of the remaining age groups, we find that group 56-65 has four times more people than group 36-45, while group 46-55 has 1.125 times more people than group 36-45.
Thus, none of the given age groups have twice as many people as another age group. Therefore, the answer is none of the options provided (N/A).
impatient much?
well, the counts, in order, are
1, 3, 4, 8, 9, 12, 15
which of those numbers is twice another?
