To determine the relative frequency of the percent of 7th graders who prefer mountains, divide the number of 7th graders who prefer mountains by the total number of students:
40 / 310 = 0.129
Convert this to a percentage by multiplying by 100:
0.129 * 100 = 12.9%
Rounding to the nearest tenth, the relative frequency is 12.9%.
Therefore, the correct response is 26.7%.
