请数学老师讲解 一下图片题
另外我之前问的一道题 您没有解答清楚b选项
A certain list consists of 3 different numbers. Does the median of the 3 numbers equal the average (arithmetic mean) of the 3 numbers?
(1)The range of the 3 numbers is equal to twice the difference between the greatest number and the median.
(2)The sum of the 3 numbers is equal to 3 times one of the numbers.
曼哈顿里的例句
A hard worker and loyal team player, the new project was managed by Sue.
书上说的是前面的modifier会错误修饰project,但平时阅读的时候读到这个是能够判断这个修饰语是不会用来修饰project的,会对阅读产生阻碍但不会令人误解。因此想问Gmat语法中这种例子是绝对不对还是不优呢。
