[計量] 幾題數學
3. A set contains 2 numbers and all the intergers in the set are
multiples of an interger M . If the highest integer in the set is 250, then
Col A: m
Col B: 5
一個集合包含兩個數字 在這個集合理的整數都是一個整數M的倍數
如果該集合內最大的整數是250 則
也就是說m有很多的意思
答案D?
14. If there are 33 balls arranged in 7 boxes which of the following is true.
(i) At least one box has more than 5
(ii) There are more than one boxes with 4
(iii) There is at least one box empty
A. I only
B. ii only
C. i and ii
D. i and iii
E. None
這題印度網站上看到比較完整的題目
但是我覺得答案是E
他完全沒說box的條件 也就是說33個球都丟同個box也行?
1. If standard deviation of 'p' number of people is 21.5 and standard
deviation of 'q' number of people is 9 then what is that least
possible standard deviation value when both p and q are added?
有人會解這題嗎
