The relative frequency can be calculated by dividing the number of 7th graders who prefer mountains (40) by the total number of students (310), then converting it to a percentage.
40 / 310 = 0.129
0.129 * 100 = 12.9%
Rounded to the nearest tenth, the relative frequency of 7th graders who prefer mountains is 12.9%.
