Just took my first GMAT prep test (CD) and am in shock to realize
how bad my quant (not to mention my verbal) is.
Anyways will really appreciate if anyone sheds some light to the
following 3 Qs! Thanks!
----------------------------------------------------------------------------------
1. Which of the following inequalities has a solution set that, when graphed on the number line, is a single line segment of finite length?
(note: <means>=, greater than or equal to)
A. X^4>= 1
B. X^3 <27>=16
D.2<= ㅣx l <=5
E. 2<=3X + 4 <=6
(Answer is E)
2. For every integer k from 1 to 10, inclusive, the Kth term of a certain sequence is given by
(-1)^k+1 * (1/2^k)
If T is the sum of the first 10 sequences, then T is...
A. greater than 2
B. between 1 and 2
C. between 1/2 and 1
D. between 1/4 and 1/2
E. Less than 1/4
Answer is D
3. The perimeter of a certain isolesces right triangle is 16+ 16 root 2.
What is the length of the hypotenuse in the triangle?
Answer is 16
