The circle graph above shows the distribution of 200,000 physicians by specialty. Which of the following sectors of the circle graph represent more than 40,000 physicians?
Indicate all such sectors.
选项 A、Pediatrics
B、Internal Medicine
C、Surgery
D、Anesthesiology
E、Psychiatry
答案A,B,C
解析 One approach to solve this problem is to find out what percent of 200,000 is 40,000 and then compare this percent with the percents given in the circle graph. Because= 0.2, it follows that 40,000 is 20% of 200,000, and any specialty that has more than 20% of the distribution has more than 40,000 physicians. This is true for the specialties of pediatrics, internal medicine, and surgery. The correct answer consists of Choices A, B, and C.
