|采纳率100%- 这道题的难度主要是对quartile的理解.
Mark原来处于the second-highest salary in the first quartile of the 80 salaries.,意思是:把80人按工资多少排列,平均分成4组,Mark处在最低的那一组的第二高的位置,也就是所有人的第62名(1-20为第一组,以此类推).
新来了8个低工资员工之后,总人数变成了88,Mark所在的第62位不变,但是这时候62是处于从最低开始数第二组的倒数第五位了(因为每组变成了22人,他现在是第三组的了,这一组是从45-66). - 1年前

|采纳率- quartile是从小到大排,马克是80人里的 第一个四分之一的 第二大,所以是19.
来了8个最低的之后 马克就成了27, 现在每四分之一22 人, 所以马克在第二个组 的第五个 - 1年前

乘积为偶数 包含 奇数*偶数,偶数*偶数
只有在 奇数*奇数的情况下,乘积才为奇数

|采纳率94.4%这个是图画得不准,AB和具体数标的位置有点问题,需要的话你可以查一下原版的真题,就是No题和国内题.从更大的角度看,实在没必要在这样一道题上浪费时间,数学的话,一是专业词汇,二是应用题的长难句.这两个不会还值得细细研究一下,像这道题就算了吧,考试真出了你一定会的.1年前查看全部

|采纳率100%X从1到100的整数,问ABCD中哪一个是标准差最大的,greatest而不是freatest,显然选E
不需要X从哪里到哪里,方差一条性质就是D(AX)=A^2*D(X),所以X系数大的就是标准差最大的1年前查看全部

|采纳率85.7%markup意思是加价,可以理解为利润,它的百分比是以成本做基础的.
the selling price of B is 80 which include a markup that was 25 percent of the cost of B:
B的售价是80,其中包括占成本25%的利润值.
故(1+25%)* cost of B = 80
