To calculate the relative frequency of the percent of 7th graders who prefer mountains, we use the formula:
Relative frequency = (Number of 7th graders who prefer mountains / Total number of students) x 100
From the table, we can see that the number of 7th graders who prefer mountains is 40 and the total number of students is 310.
Relative frequency = (40 / 310) x 100 ≈ 12.9%
Therefore, the relative frequency of the percent of 7th graders who prefer mountains is approximately 12.9%, which rounds to 13% to the nearest tenth.
So, the correct answer is not provided in the options.
