What percent of those who submit applications for admission enroll in classes at the university? (1)Fifteen percent of those who submit applications for admission are accepted at the university (2)Eighty percent of those who are accepted send a deposit to the university 答案是E 选的是C 可能是题目没有理解好 我觉得submit applications的人中有15%被学校给accepted了,而被accepted的人中又有80%的send a deposit to the universityle 了,那么不就是15%*80%的人enroll in classes at the university 了吗? 请大家指正错误
3.Is the measure of one of the interior angles of quadrilateral ABCD equal to 60 degrees? (1)Two of the interior angles of ABCD are right angles (2)The degree mesure of angle ABC is twice the degree measure of angle BCD 答案是C 选的是E 觉得既可能是∠ABC=90°∠BCD等于45° 也可能是∠ABC=120°∠BCD=60°啊?作者: 卮言浅夏 时间: 2010-5-9 23:49
