If |x^2 - 2| <7 which of the following best describes x?

A. -3<x<5
B. -5<x<3
C. -Root(5)<x<3
D. -3<x<3
E. 0<x<3

Can anyone please explain how D is the correct answer?

I have got the below -5<x^2<9, so have we skipped -5 because the root of it will be imaginary number?

Quadratic equations are asked in GMAT Quant. You may not expect complex graph based questions using parabola.

There are couple of ways - 1) You can post your question in the discussion thread if there exists one. If not, you can create one by yourself. 2) You can post quant questions / queries on this chat group and verbal ones in the verbal chat group. 3) If you have a specific query on a topic, you can always create a post and tag an expert for their response.

I didn’t find any precise answer. Closest I could get is 27/1000.
Solution:
50 Defective; 450 Good
50C2*450C1 / 500C3 = 49*45*3 / 499*498 = 27*245 / 499*498 = 27/499*2.03 = 27/1012

"Chosen randomly" - does this mean that the bulbs are not picked? In other words bulb is selected and placed back before next selection?
In such case, we can use faulty coin toss concept-
3C2 * (0.1)(0.1)(0.9) = 27/1000
This is not entirely clear, don’t know how do we differentiate between the two.

Andy is planning to go from A to B. He needs to reach B for an important meeting scheduled. He must be on time. After travelling for some time he realises that he will cover only 2/3 rd of the distance by the time the meeting starts. Hence, he increases speed to 2.5 times his initial speed. Thus he manages to be exactly on time. If he had not changed his speed he would have been 4 hrs late for the meeting. After travelling for how many hours did Andy change his speed.? Need solution pls

Ans - 16/3 hrs? (I’m half asleep, silly mistake alert :) )
Solution -
We need to consider 2 splits for the route. Call distance "x"
1) x= 2/3 & 1/3 ; as per hypothetical condition
2) t= t1 + t2 ; actual situation
also, 2.1) x = vt1 +5v/2 * t2 ; actual situation
Case 1: 2x/3 = vt and x = v(t+4); hence, t=8
( So, by 2)) t1+t2=8; ---- EQ1
(by 2.1) vt1+5v/2 * t2 = v(t+4)
hence, 2t1+5t2=2t+8=24 -------- EQ2
solve 2 equations t1 = 16/3; t2=8/3
