Re: [計量] 印度網站的Q 數題
※ 引述《KRZYSZ (VICTORIA)》之銘言：
: Given a series.
: 1, 1/(2t), 1/(2)^2*t, 1/(2)^2*(t)^2 .................
: For t=2, if odd terms are 1/2 times the previous number and even terms are
: 1/(t) times the previous number, then
: Col A: The eight term (8th) in the series
: Col B: 1/(2)^8
: Ans: C
因為t=2
序列為
1,1/4,1/8,1/16....1/2^n
所以第八個是1/2^8
: it really seems strange to me as the question describes that t=2
: and gives the series at the begining.
: the question seems to have two different definitions of the series?
: In a contest, there are 5 judges who are to rate (they can rate from 0-10)
: the scores of 8 different groups.
: Category Scores
: Solo 14
: Group 17
: xxxx 25
: xxxx 29
: xxxx 31
: xxxx 35
: xxxx 44
: xxxx 49
: What is the minimum number of teams, which must get 7 or more than 7 score
: from atleast one judge?
: Ans:4
至少從一位裁判得到至少七分以上
=
全部 - 沒有從任任裁判得到至少七分以上
=
全部 - 所有裁判都給六分以下
=
全部 - 總分小於30分的隊伍
=
8-4
=
4
: how and what concept should i have to cope with the question like this?
: Given stock price at end of February as x. If stock price increase in March
: is 10% & increase in April is again 10% and if May price = 70% of April
: price, then
: Col A: The May price
: Col B: 0.9x
