二战裸归680，放狗+三战征战友 - 更新在主页

回来了，二战裸考，M50 V30, 还要3战。数学思维没变，但是我的记忆力太差了，等我想想：
一个半月后 再战目标730
1. 最后一道题
What's the value of n?
1) 2^n = n^2
2) n is a positive integer (or number)

1) n = 2 or 4 , insufficient 2) insufficient 1)+2) insufficient
so E

2. Which line in the following is perpendicular to line y = 5x
Answers included: y = -5x , y= (1/5)x, y = (-1/5)x
My choice: y=(-1/5)x , as slope of line1 multiple slope of line2 = -1

3. What's the degree of angle X? please refer to the following picture(numbers might be not accurate) cause I remember my answer was 100

4. A new type of graphic question, 30 students in a certain group, please refer to the following graphic which indicates the relationship between the number of students and the frequency they did certain activity (not accurate), ask what’s the probability for a student to did certain activity more than 1 time of the median (or average!!友情提醒，一定要注意这个好像是Median我算成average了) of the group
当时刚回来只记得一点点英文，我用中文说一下吧
是一道新的看图题，图是下面的，说是一个group有30名学生，每个学生做多少次的一个什么activity如下图显示，图上标了横轴是做这个activity的次数纵轴是学生人数。问一个概率，学生做这个activity的得次数跟这个图所示的Median(不是average)相差多于1次（我的理解：即大于或小于的多于1次）的人的概率。 这样应该清楚一些。 （good luck, 不难就是绕了几道弯，很容易错要仔细读题）

5. 2(2/3)+5(2/3) is how many times of 3/25

6. 第28只狗
这道题我记得，我选的是50%,我开始也看错了，我的问的好像是 What's the percentage of the employees who have Business degree and also speak French?  （my understanding is that: 20% / 40% ）没有20%的选项，所以看错了又重新算了，good luck
20%大家都会算，不多说了，我猜狗主人遇到的题目很有可能是
What percent of the employees who have Business degree can speak French?
是问在总量为40%里面，那个20%占了百分之几，应该是50%吧

阅读JJ,一篇最长（一屏半）的是GWD上的吗？我记得我做过但是不记得是在那个上做的
第一段，一个钟非常的准确是一个叫David什么的人1842年？发明的，然后就描述了钟的两个钟摆怎样function, (有一道细节题问这段可以infer出什么) 定位就是这个部分但是必须读懂
第二段，介绍钟的准确程度还有对科学的特殊贡献，有一题问有关的就是在这儿定位
第三段，介绍另一个人用其他的电子设备模拟钟的实验，（有一道问something not mentioned类的题只须泛读我觉得）
第四段，潮汐对钟准确性的影响 （也有个选项涉及这个建议泛读）

1) n = 1 or 2 , insufficient 2) insufficient 1)+2) insufficient

我觉得应该是A,1）中：2^1=2,1^2=1，所以答案是2，2）中，不充分，所以选择A;
2. Which line in the following is perpendicular to line y = 5x
Answer include: y = -5x , y= (1/5)x, y = (-1/5)x
Answer y=(-1/5)x , as slope of line1 multiple slope of line2 = -1
Y=-(1/5)X
3. What's the degree of angle X? please refer to the following picture(numbers might be not accurate) cause I remember my answer was 100

4. A new type of graph question, 30 students in a certain, please refer to the above graphic which indicate the relationship between the no of students and the frequency they did certain activity (not accurate), ask what’s probability for a student to did certain activity more than 1 time of the median (or average!!  友情提醒，一定要注意这个好像是Median我算成average了) of the group

LZ第一道题难道不是E吗？

n^2=2^n，n可以等于2，也可以等于4吧。
