Explanation:

Step1: Count students riding over 10 miles

Count the numbers in the data - set that are greater than 10. The numbers are 13, 12, 15, 12, 12. There are 5 such numbers.

Step2: Determine the value of x

The fraction $\frac{x}{30}$ represents the ratio of the number of students who ride more than 10 miles to the number of students surveyed. Since the number of students who ride more than 10 miles is 5, then $x = 5$.

Answer:

5
