Of the 1,400 college teachers surveyed, 42 percent said that they considered engaging in research an essential goal.How many of the college teachers surveyed were women?
(1) In the survey, 36 percent of the men and 50 percent of the women said that they considered engaging in research an essential goal.
(2) In the survey, 288 men said that they considered engaging in research an essential goal. 答案选的A,我看了一下破解版,是这样解的。。。“total(1400) x =588(參加人數) , 588 x women比例(50%)=參加女人的比例 , 充份”
但是我觉得“50%的女人说她们要engage”和“总的表示要engage的人中有50%的人是女性”是有区别的。。。所以我觉得这个解答有问题,望哪位NN指教~~ 但是我觉得“50%的女人说她们要engage”和“总的表示要engage的人中有50%的人是女性”是有区别的。。。所以我觉得这个解答有问题,望哪位NN指教~~ |
