[機經]9月份新鮮的,幾題不太確定,請大家來討論討論。
1.Space diangonal is a diagonal connecting two vertices on different planes.
If 邊長 of the cube is 5. What is the diagonal?
請問這題要怎麼解呢?
遇到這種題型真是我的死穴
3.ABC is a triangle. D is the midpoint of BC. E is the midpoint of AC
while F is midpoint of EC, If area of triangle ABC is 24
What is the area for triangle DEF ?
關於這題我的想法是 邊長變為原本的 1/2 ,且底邊變為1/4
所以面積為原本的1/8 ,所以這題是 24 *1/8= 3
但是CD 上也有人說 答案是8 ,所以我想請問,這一題要怎麼思考?
4. A class of 35 students take part in an test. How many students are below
the average score?
1. The average score is 86
2. The median score is 86
這題我選E ,不過也有人 選C
所以想參考大家的意見
以上,麻煩大家。
