7月17GRE数学真题及答案数学部分直接计算题1.

According to a tax rate formula for a certain year, the amount of tax owed by an inpidual whose annual income was between $31,850 and $77,100 was equal to a base tax of $4,386 plus 24 percent of the annual income that exceeded $31,850.

According to this formula, what was the amount of tax owed by an inpidual whose annual income that year was $42,000?

答案：6822解析：题干问，某一年个人收入在$31,850到$77,100之间的税收计算方式为$4,386加上超出$31,850部分的24%。

问收入为$42,000的个人这一年需缴纳多少税?

所以我们可以得到所缴税的计算方式=4386+24%*(42000-31850)=6822.

大小比较题2.

x=2, y=3,z=5Quantity A: x^-1*y*z^-2Quantity B: (y/xz)^2A.

Quantity A is GREater.

B.

Quantity B is greater.

C.

The two quantities are equalD.

The relationship cannot be determined from the information given.

答案：A解析：A的值= x^-1 * y * z^-2=1/2*3* 1/25=3/50B的值= =(y/xz)^2=9/100因为A=0.

06,而B=0.

09，所以AB.

3.

x y-2Quantity A: The average (arithmetic mean) of x and yQuantity B: y-1A.

Quantity A is greater.

B.

Quantity B is greater.

C.

The two quantities are equalD.

The relationship cannot be determined from the information given.

答案：B解析：A的值=(x+y)/2， B的值=y-1.

所以A-B=x/2+y/2-y+1=(x-y)/2+1由题干得，x y-2，所以x-y-2因此，(x-y)/2+10则A图表理解题4.

X Frequency 0 6 1 11 2 18 3 23 4 15 The table shows the frequency distribution of the random variable X.

What is the median of the distribution of the values of X ?

A.

1.

0B.

1.

8C.

2.

0D.

2.

5E 3.

0答案：E解析：题干要求变量X值的中位数，表格左侧为数值，右侧为出现次数。

因为总的次数=73，所以中位数是第37位，则落在数值3上。
