提问:

47.问 13个数的中位数 是否得20? 条件1 6 numbers are less than or equal 20 条件2 6 numbers are more than or equal 20. 6.唯一有个题没找到思路,蒙的。5的K次方是大约是从99到199中的奇数的乘积,包括两端,求K(答案有13,15,20之类的)想了半天没搞出来(可能理解有误,大家不要纠结。。。)某位筒子的答案是13 7.ABCDEF六个人坐一张桌子,问A和FB相邻,B和AC相邻,C和BD相邻,D和CE相邻,E和DF相邻,F和EA相邻的概率这题没思路啊排列组合太差了怎么办啊 55.抛物线,y=(x+2)^2+1, 抛物线上一点(a,b) 问如下哪一个不对 答案是诸如a>0, b>0 a<0, b>0 这样的东西 其实就是考察的,抛物线在y轴右边部分单调增,且节距大于0,于是X>0的时候Y>0 60. DS:告诉一个正整数,它恰好有6个因数,问这个数是多少 1. 6个因数中有两个是质数 2。这个数小于15。 我选B。 符合1的数不唯一,如12,28; 符合2的只有12。

提问:

PS:总共66个学生,有18个是business major,24个是新生,还有36个什么也不是,我忘了最后是问,仅仅是新生不是business major 的还是仅仅是business major不是新生的? 构筑答案:好像答案不是12 就是16.。。 解析: 18和24代表的韦恩图圈圈有重合,36代表的是自己单独的圈圈。 Total =66; 36个学生不在Business和Fresh 范畴里面,所以F+B=30; F 和B的共有学生=12, 是B不是F=6; 是F不是B=12。
