The circle graph shows the percent of the total concussions in high school sports according to a study done by the Sports Concussion Clinic, Division of Sports Medicine, Children’s Hospital Boston. Use this pie chart to answer questions 4 through 7. Suppose that there were 450 high school athletes who participated in the study.

4. Find the number of people who had a concussion in Softball. Round your result to the nearest whole number.

5. Together, how many of the concussions are either in boy’s soccer or girl’s soccer?

6. How many concussions are in the largest category? Round to the nearest whole number.

7. What sports combined makeup 20% of the concussions?

Answer 1

softball	4%
baseball	1%
wrestling	7%
girl basketball	7%
boy basket ball	4%
volleyball	1%
girls soccer	12%
boy soccer	7%
football	57%

total =450

4)

number of people who had a concussion in Softball = 4% of 450 = 18

5)

concussions are either in boy’s soccer or girl’s soccer = (12% +7% ) of 450 = 19% of 450 = 86

6)

concussions are in the largest category in football = 57% of 450 = 257

7)

baseball	1%
wrestling	7%
girl basketball	7%
boy basket ball	4%
volleyball	1%
total	20%

boy basket ball can also be replaced by softball because that is also 4%

Boy soccer is also 7%
