1. Problem Description

A survey of 2400 people asked them to name their favorite sport to watch. The circle graph summarizes the answers. The central angle for the Basketball slice is 5454^\circ. We need to determine how many people named Basketball as their favorite sport to watch.

2. Solution Steps

The total number of people surveyed is
2
4
0

0. A full circle has $360^\circ$.

The fraction of people who chose basketball is represented by the ratio of the basketball slice angle to the full circle angle.
Fraction of people who chose basketball = 54360\frac{54}{360}
To find the number of people who chose basketball, we multiply the total number of people surveyed by the fraction of people who chose basketball.
Number of people who chose basketball = 2400×543602400 \times \frac{54}{360}
First, simplify the fraction:
54360=27180=960=320\frac{54}{360} = \frac{27}{180} = \frac{9}{60} = \frac{3}{20}
Now, multiply the total number of people by the simplified fraction:
Number of people who chose basketball = 2400×3202400 \times \frac{3}{20}
Number of people who chose basketball = 2400×320=720020\frac{2400 \times 3}{20} = \frac{7200}{20}
Number of people who chose basketball = 360360

3. Final Answer

360
