To determine the relative frequency of the percent of 7th graders who prefer mountains, you would use the following formula:
Relative Frequency = (Number of 7th graders who prefer mountains / Total number of students) x 100
So, for 7th graders preferring mountains, the relative frequency would be:
(40 / 310) x 100 = 12.9%
Therefore, the rounded percentage to the nearest tenth is 12.9%.
None of the provided options are correct.
