问题如下:
Analysts collected some information:
According to basic fundamental law, please calculate the number of independent decisions made per year:
选项:
A.1.56
B.1.2
C.1.74
解释:
C is correct.
考点:考察basic fundamental law 的公式:IR=IC*√BR
解析:这个题是已经给了IR和IC,TC是干扰项。 直接代入公式:
BR=(0.66/0.5)2=1.74
老师,我想问一下,为什么BR不是一个整数?他不是一个number of independent decisions么,不是一个次数嘛?
