D 55%

Answer 1

To determine the relative frequency of the percent of 7th graders who prefer mountains, we need to divide the number of 7th graders who prefer mountains (40) by the total number of students (310), and then multiply by 100 to convert to a percentage:

(40/310) * 100 = 12.9%

Rounding to the nearest tenth, we get 12.9%, which is closest to option B. Therefore, the correct answer is B) 26.7%.
