惨败归来,败在了数学上了,M<45, 愧对小学和初中数学老师。 考到了机经有: AA:The following appeared as part of a business plan by the Capital Idea Investment firm. “Currently more and more books are becoming available in electronic form — either free of charge on the Internet or for a very low price per book on CD-ROM.* People who would not pay bookstore prices will now have access to whatever book they want from their home or work computers. Consequently, literary classics are likely to be read more widely than ever before: 72 percent of those responding to a recent online survey said they would read books in electronic form, and 81 percent said they believed that reading classic works was important. Given this newly developing market, we should invest in E-Classics, a new company that sells electronic versions of literary classics.” *A CD-ROM is a small portable disc capable of storing relatively large amounts of data that can be read by a computer. AI: “The most effective business leaders are those who maintain the highest ethical standards.” 两个都在黄金80里面 一道CR 一个城市的shrimp产量20m,但是retail store只卖11m,但是这个国家不会出口。 问strength. 还是选原来“有好多饭店不从retail 卖shrimp”那个。
JJ:30问1/(根号下27)+根号下0.0099 最接近几?(我考的这个是变体) 35. DS. X 是正整数,问有几个不同的质因子 1) x/5是整数并且只有一个质因子(divisible for exactly 1 prime factor) 2) 3(x^2)有两个质因子 (divisible for exactly 2 prime factors)
1)说明X=5*(一个质数^n),X可能有两个不同的质因子(5 和另一质数)或只有1个(另一质数为5^n时) 2)说明X是一个不是3的质数(如2,5)或者这个质数的次方(如2^2, 5^3),或者可以拆成3和某个质数(或该质数次方)的乘积(如3*2, 3*2^4),所以X可能有1个(如x=2的时候)或者2个(如x=6的时候)不同的质因子 1)+2)还是不能说明,因为X可以是5^n或5*(3^n) 选E JJ51. DS: 整数n是不是一个数的平方?1)4n是一个数的平方 2)n^3是一个数的平方 答案为D 100、DS,直线y=ax+b经过(1,5),和另一直线相交于(5,t),求t (1) 给出直线和y轴的截距(有具体数字) (2) 另一直线的slope为2 106、DS,有255个人,抽出一个人为女人且有大学学历的概率小于1/2? (1) 其中125个人有大学学历 (2) 其中130个人为男人 122一个agent买房子有5%的提成,具体价格有点忘记了这里用abcd表示,他a元的-b元的卖了2套,c-d卖了1套,e-f卖了2套,问他拿了多少提成,5%*(2a+c+2e)与5%*(2b+d+2f)之间,答案是8500-15500 130 一个正六边形 面积是96(3)1/2 问边长 140 P(x)=x的组成数字相乘,如P(258) = 2*5*8 = 80 (这个数字是我自己编的,表达题目的意思) 以下何者为真? (I) P(10x) = P(x) (II) P(x+1) > P(x) (III) P(2x) = 2P(x) 130 一个正六边形 面积是96(3)1/2 问边长 140 P(x)=x的组成数字相乘,如P(258) = 2*5*8 = 80 (这个数字是我自己编的,表达题目的意思) 以下何者为真? (I) P(10x) = P(x) (II) P(x+1) > P(x) (III) P(2x) = 2P(x) 低分区一道,(1-x^4)/(1-x)=? RC记不清楚了,就不误导大家了。
