Question

maria and yolanda like to walk for exercise. this table shows how far they walked for two weeks.

number of miles	maria	yolanda
3 - 3.9 miles	7	1
4 - 4.9 miles	2	3
5 - 5.9 miles	5	2
6 miles	2	8

which histogram represents maria and yolandas combined walks?

Explanation:

Step1: Calculate combined number of walks for each interval

For 2 - 2.9 miles: $2 + 4=6$
For 3 - 3.9 miles: $7+1 = 8$
For 4 - 4.9 miles: $2 + 3=5$
For 5 - 5.9 miles: $5+2 = 7$
For 6 - 6.9 miles: $2+8 = 10$

Step2: Match with histograms

Check the heights of the bars in each histogram for the corresponding mile - intervals to see which one has the correct frequencies.

Answer:

The correct histogram is the one where the bar - heights for the intervals 2 - 2.9, 3 - 3.9, 4 - 4.9, 5 - 5.9, 6 - 6.9 miles are 6, 8, 5, 7, 10 respectively. Without seeing the exact details of each option's bar - heights, you would compare these values to the histograms labeled A, B, C, D to pick the correct one.
