To determine the relative frequency of the percent of 7th graders who prefer mountains, you would divide the number of 7th graders who prefer mountains by the total number of students:
Number of 7th graders who prefer mountains: 40
Total number of students: 310
Relative frequency = (40/310) * 100% = 12.9%
So, the rounded percentage to the nearest tenth would be 26.7%.
Therefore, the correct answer is:
