[問題]來欣數學Q部分
很久以前補的 後來都翹課 沒去聽 請大家幫忙解答一下
Q8
1.這個是要看圖的
題目:What is the median quiz score?
是只要找列出來的分數的median嗎?
不知道有沒有改答案 答案是B.7 我覺得好怪唷 題目指的中間數 怎麼會是7咧?
不知道是不是我誤解題目的意思了
24.If two trains are 120 miles apart and are traveling toward each other at a
constant rate of 30 mph and 40 mph, respectively, how far apart will they be
exactly 1 hour before they meet? Ans:E.70 miles
我算50 miles 難道是我誤解題目的意思嘛? "how far apart"應該是指兩輛火車的距離吧?
走ㄧ個小時 ㄧ輛走30 另ㄧ輛走40 120-30-40=50
Q1
23.Sixty-eight people are sitting in 20 cars and each car contains at most 4
people. What is the maximum possible number of cars that could contain exactly
1 of the 68 people? Ans:C.4
我看不太懂題目要我們求什麼(￣▽￣＃)﹏﹏
是只每個人最多有幾輛車可以做嗎(．＿．?)
