M50,V太烂,离预期的差距太大,准备二战


AWA:AA-40:With the increasing emphasis on a global economy and international cooperation, people need to understand that their role as citizens of the world is more important than their role as citizens of a particular country

AI-31:Studies suggest that an average coffee drinker’s consumption of coffee increases with age, from age 10 through age 60. Even after age 60, coffee consumption remains high. The average cola drinker’s consumption of cola, however, declines with increasing age. Both of these trends have remained stable for the past 40 years. Given that the number of older adults will significantly increase as the population ages over the next 20 years, it follows that the demand for coffee will increase and the demand for cola will decrease during this period. We should, therefore, consider transferring our investments from Cola Loca to Early Bird Coffee.

阅读:考到一道GWD-24-Q25-Q27,就是W.E.D.Bois的那道,应该很好找的

Math:1。102、108、114……是一个数列an+3= an+18,问下面选项里哪个数是这个数列里的,记得的数有488,592,594,偶选的是594,其实就是个d为6的等差数列

2。一个梯形ABC D,上底AB=5,下底C D=9,下底从D点延伸出去到E,已知三角形ACE(刚刚笔误,改过来了)和梯形的面积相等,求DE的长度。DE的长度应该就等于AB的长度,偶的答案是5(实在是不知道怎么贴图,不好意思啦)

3。汗,怎么记得的都是我觉得别人不会做错的题,2-3-3-2=?,答案是72-1

4。有一个柱状的统计图,是69个学生的生物成绩,有9个区间40-49、50-59……(具体的记得不太清楚了)人数分别是10、13、12、7、3、2、5(这四个数字可能有误,不过不影响结果就是了)、10、10,求median。答案应该是12对应的那个区间。

5。DS:一个CLUB里有些人,从中选出一个人,这个人有college degree的概率是多少?(1)有college degree的概率是无college degree概率的2倍;(2)无college degree概率是0.3。我的答案是D

6。DS:问x>y?  (1)x/y>1 (2)x/y<4。我选的A

7。一个正方形内切一个圆,圆的周长是10pie,求正方形的周长。我做出来是40

8。3X-2Y=32,根号下3X-根号下2Y=4,求X-Y。我做出来是10

9。XY-Plan里有一个正方形,给了3个点的坐标,貌似是(2,3)(2,5)(4,5),求一个点的坐标到这四个点距离相等。答案好象是(3,4)。记得不太清楚了,挺简单的。

10。1/(2953),问小数点后到第一次出现nonzero的数,之间有几个0?好象是4个吧,化简一下就出来了。


又想起来一道:11。DS:9-grade和10-grade的学生,有60%是10-grades的,问学生物的学生是否超过40%?(1)25%的9-grade学生学生物(2)70%的10-grades的学生学生物。偶选的B,10-grade学生里学生物的已经有42%,超过40%了
