The following appeared in an Avia Airlines departmental memorandum.

On average, 9 out of every 1,000 passengers who traveled on Avia Airlines last year filed a complaint about our baggage -handling procedures. This means that although some 1 percent of our passengers were unhappy with those procedures, the overwhelming majority were quite satisfied with them; thus it would appear that a review of the procedures is not important to our goal of maintaining or increasing the number of Avia’s passengers.

先写本月jj中出现的题吧：12，19，24，25，43，45，47，62，71，97，99

1． 用小正方形和三角形分别定义了两种运算，进行计算。a正方形b=(a+b)/2; c三角形d=(c-d)/2, 求（1正方形3）三角形（2正方形4）=？ 答案-1/2 （具体数字有点记不清了，大概是这样子的）

2． DS: 求p^xy的个位数

（1） p^x 的个位数是1；（2）p^y的个位数是1

我选D

3． DS: n是正整数，且不是任何一个整数的平方，问n是不是质数

（1） n的因子中，唯一比n^0.5大的数是n本身；（2）n的因子中，唯一比n^0.5小的数是1

我选的D

4． DS：一条直线l在y轴的截距小于-2，问x轴的截距是否比3大

（1） 直线l经过一点（具体坐标不记得了）；（2）l的斜率是1/2

我选B

5． Sn=1/n^2 – 1/n ,求S1+S2+S3 选项有0，-1到-1/2，-1/2到0之间（答案）……

就记得这么多了，想起来再写

Verbal部分就不写了，水平实在太烂，怕写出来误导大家

祝各位好运！
