At the up-right coner of the 1st floor, you can see several button. Choosing the 1st one, "Ping Ban", you will be able to see the cascade style, which shows the questions from 36 through 50. Sorry, this computer with English OS I can't input Chinese.

39题什么意思啊？

(1/8)^2=((1/2)^3)^2

.025^2=(1/4)^3=((1/2)^2)^3

Q 48, 48. (同本月JJ-19） DS:100个儿童，求x的值
age 7 8 9 10 11 12 13
frequency 18 20 x 16 18 y 13
1) median age 9.5
2) y>10

answer E?

我觉得是a,y不能大于10

Chelseaww

47的问题是不是应该是x/(4x+y)<0? 如果是x/(4x+y)<1,好像没法解。。。难道选e?

49题怎么解？？？

50题是不是e?因为好像a-d不像对的，那难道刚好是忘了的那个？
