青霞,刚突然想来复习下全部概率题目,于是就跑你这帖子里来了,果然找到了
高人能指点一下这道题目吗? 我都看不懂意思.figure是什么? a ratio of the remaining sum of integers又是什么意思?
还有Find a median of n consecutive even integers (1) Median is a ratio of the remaining sum of integers (2) the sum of remaining integers excluding median is a figure
由条件1可知:me=1/3(av*n-me) 虽然av知道了但是n还是未知,所以me还是无法求出
加上条件2:av*n-me=256,联合条件一就可求出me
答案 C
只想对你大声说:"你实在,实在...太有才了!"
喜欢你的说话方式呵!
(1) n^2可以被30整除, 说明2,3,5是n^2的因子,说明也是n的因子,所以充分
(2)2n 可以被30整除, x=15,30,不充分
A
