我21就考了,快点,牛人帮帮我啊~~~谢谢~~现在如果觉得哪个答案有误的就来吼一下啊~~
版本2:问1个整数N, (N+1)(N-1) 能不能被10整除(好像是10)? (1)这个整数不能被2 整除 (2)这个整数不能被3 整除 E??
***新的~~ DS说[x]是大于x的最小整数,问x-[x]是否大于零还是小于零,没关系,反正答案都是一样的(1)x>0,(2)x不是整数 我选b
这个答案不是D么? 结果肯定是小于零 不是说【X】大于X的么~~
m的n次方是perfect square? (绝对平方:9=3*3,25=5*5这类的) a, m是perfect square b, n是perfect square A
有一个公司开会啥的,要么是stock holder, 要么是employee,要么都是,好像是stock holder有64%, employee是48%,问是stockholder不是employee的。 (1)都是的占30%(不确定具体数值) (2)都不是的9%(也不确定具体数值) 最后选的D
3@2=3,3@4=4,20@y=30,有几个可能的y值 1,2,3,4,5
A 不确定~
13个数的中值 a 有六个数大于50 b. 有6个数小于50 c,有at least等字样,那该题就是选E 31 In a 100 pounds fruit, 99% is water. After dehydrating, the water content is 98%, the weight of fruit content remains unchanged, what is the weight of the fruit? --> originally 1 pound is the weight of the fruit content, assume x is the water content after hydration, then x/(1+x) = 0.98, x=49, answer = 50 pounds 设脱水x, (99-X)/100-X=98% X=50,因此水果50 29 求6是否(m+1)(m-1)的factor (1)m is not divisble by 2 (2) m is not divisble by 3 C
28 求过去13天卖书的median (1)过去7天每天卖43本 (2)过去13天卖了400本, 选A~ 26 exchange rate: 1US = 0.8Euro, additional charge 4% on Euro. How much euro is exchanged for $1830 USD? 1830*0.8*(1-4%)
