以下是我記得的題目
AI:“No one can possibly achieve any real and lasting success or ‘get rich’ in business by conforming to conventional practices or ways of thinking.”

AA:The following is taken from an editorial in a local newspaper.
“Over the past decade, the price per pound of citrus fruit has increased substantially. Eleven years ago, Megamart charged 5 cents apiece for lemons, but today it commonly charges over 30 cents apiece. In only one of these last eleven years was the weather unfavorable for growing citrus crops. Evidently, then, citrus growers have been responsible for the excessive increase in the price of citrus fruit, and strict pricing regulations are needed to prevent them from continuing to inflate prices.”
數學部份
1.有個數值落在(-3)~(-4)间,哪個數是符合這個區間的-->10開根號
2.X開三次方=2 X的四次方開根號=?-->64
3.K表示1/N形式的總和,N=33~64,求K的範圍 我選了1/32<K<1/2,
我不確定,大家算一下吧
4.(X+1!)/X!=? -->X+1
5.Xn=2Xn-1 X1=3 X20-X19=? -->2^19-1
6.(1)abc is even (2) ac is odd, 問is a+b+c even? 我選了c
7.給一個平面座標,上面有5個點,哪一個滿足y+3<x-1
可簡化成 y-x<-4 用題目給的點帶入,選e
8.(x+y)(x-y)-y^2=?? (1)x=某個值 (2)y=某個值
-->化簡後變成x^2 所以選a
9.10公斤的混凝土,有30%sand、70%humidy(忘了是什麼),今天要重新
調配10公斤混凝土,上述的兩種東西比例要變成各50%,我們要加多
少的sand進去取代原有的混凝土? -->設加進去sand x公斤
(10*0.3+x)/10+x X=4 ---->這題不是很確定,大家算算吧
10.n除以6的餘數?? (1)n除以12餘7 (2)n除以3餘1 --->a
11.有圖,一的大半圓裡相切一小圓,問半圓內扣除此小圓的面積?
(1)給大半圓的半徑 (2)給大半圓面積=25拍 -->d
因為大半圓的半徑其實就是小圓的直徑...可以自己畫圖看看
12.抵押物在a銀行是月利率x%單利,同樣抵押物在b銀行是y%利率單利
問抵押在b銀行一年會有多少利息?(1)抵押物=10000元 (2)x%=3%
我選e--->不是很確定,其他人可以想看看
13.正六邊形面積=54根號3 問正六邊形的邊長=??-->6
14.正方形周長=k/16, 正方形邊長?? --->k/64
15.一桶藍苺賣5cent,一桶草莓賣25cent,兩種東西合起來賣了
225cent,問藍莓部份有沒有買超過某個價錢?
(1)藍莓賣的數量比2大(2)草莓賣的數量比7小
-->我選了e,各位還是看一下題好了
16.[x]是比小於或等於x的最大整數,問[x]=?
(1)x>1 (2)x<2 -->我選了c
17.is x>y? (1)x/y>1 (2)x/y>2 --->我選e,因為不知x或y是正或負
18.5^19+5^22 問有幾個正質因數? 5^19+5^22=5^19*(126)
把126坐直因數分解,=2*3^2*7*5^19,所以有四個質因數
19.求50~100的總和? (50+100)*51/2=3825
20.問標準差是多少? (1)給一個群體的平均值 (2)在一個群體中大家都是
相同的數,我選B
