To determine the relative frequency of the percent of 7th graders who prefer mountains, we first need to find the total number of 7th graders. From the table, we can see that there are 110 7th graders in total.
Next, we can see that 40 of the 7th graders prefer mountains.
To find the relative frequency, we divide the number of 7th graders who prefer mountains by the total number of 7th graders, then multiply by 100 to get the percentage:
(40/110) * 100 ≈ 36.4%
Therefore, the relative frequency of the percent of 7th graders who prefer mountains is 36.4%.
The correct answer is:
36.4%
