The relative frequency can be calculated by dividing the number of 7th graders who prefer mountains by the total number of students.
Relative frequency = (40 / 310) * 100 = 12.9%
Therefore, the percentage of 7th graders who prefer mountains is approximately 12.9%.
Use the table to answer the question.
