Question

Geraldo wants to start a group bike ride on Sunday mornings for students at his school. He asked 30 students in the lunchroom how many miles they ride their bikes each month. He obtained the following results.

8, 3, 0, 1, 2, 3, 6, 3, 0, 4, 13, 1, 3, 12, 15, 2, 1, 3, 2, 2, 0, 3, 4, 2, 6, 7, 12, 8, 4, 0

The fraction x over 30 shows the ratio of the number of students who ride their bikes more than 10 miles each month to the number of students surveyed. What is the value of x?

Answer 1

To find the value of \( x \), we need to determine how many students ride their bikes more than 10 miles each month from the given data set:

The results provided are:
8, 3, 0, 1, 2, 3, 6, 3, 0, 4, 13, 1, 3, 12, 15, 2, 1, 3, 2, 2, 0, 3, 4, 2, 6, 7, 12, 8, 4, 0

Now, let's identify the values that are greater than 10:

- 13
- 12
- 15
- 12

There are 4 values that are greater than 10.

The fraction \( \frac{x}{30} \) shows the ratio of the number of students who ride more than 10 miles (which is \( x \)) to the number of students surveyed (30 in this case).

Thus:

\[
x = 4
\]

So the value of \( x \) is 4.
