諸位大人~我現在用的是綠色的數學OG,裡面有兩道數學題怎麼看都看不懂~希望你們可以幫幫忙~ 都是DATA SUFFICIENCY ,唉,我都已經懷疑我的智商了。。。。
P153 10 of the 230 single-family homes built in city x last year, how many were occupied at the end of the year? 1)Of all single family homes in city x,90% were occupied at the end of last year 2) a total of 7,200 single family homes in city x were occupied at the end of last year
我是一直不明白那個OCCUPIED 是什麼意思,我整道題都讀不懂~
41 If S is a set of four numbers w,x,y and z, is the range of the numbers in S greater than 2? 請問,它是說S集合裡有WXYZ四個元素, 問集合S裡的排序?範圍?是不是大於2?
(掩面)不要歧視我~
請高人幫幫忙~ 謝謝~ |
