The incomplete table above shows a distribution of scores for a class of 25 students. If the average (arithmetic mean) score for the class is 83, what score is missing from the table?
选项
A、75
B、77
C、81
D、84
E、86
答案
A
解析
If the average score for the class is 83, then the sum of all 25 students’ scores be 83×25=2,075. The sum of the scores for the 22 students for whom we have scores is 368+546+581+355=1,850. So the three students’ scores must make up the difference between 2,075 and 1,850; 2,075-1,850=225; 225/3=75.
