1 answer

To determine the relative frequency of the percent of 7th graders who prefer mountains, we need to find the total number of 7th graders who prefer mountains and divide it 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%

Therefore, the relative frequency of the percent of 7th graders who prefer mountains is 12.9%.
