If the range of the six measurements 140, 125, 180, 110, 165, and x is 80, which of the following could be the value of x?
选项
A、60
B、85
C、190
D、220
E、245
答案
C
解析
若6个数140,125,180,110,165和x的范围是80,那么x可能是下面的哪一个数值?
解:本题的正确答案为(C)。6个数的范围实际上就是这六个数中最大数与最小数的差。题目中已知的5个数的取值范围显然小于80,所以x值可以是6个数中最大数或最小数:若x是最大数,则x=110+80=190;若x是最小数,则x=180-80=100
