So, here's the ACTUAL question...

Quote:
Is n > 6
1) √n > 2.5
2) n > √37
Target question: Is n > 6?

Statement 1: √n > 2.5
Square both sides to get: n > (2.5)²
Evaluate to get: n > 6.25
If n > 6.25, then we can be CERTAIN that n > 6
Since we can answer the target question with certainty, statement 1 is SUFFICIENT

Statement 2: n > √37
First recognize that √36 < √37
In other words, 6 < √37
Statement 2 tells us that √37 < n
So, we can COMBINE the inequalities to get 6 < √37 < n
From this, we can conclude that n > 6
Since we can answer the target question with certainty, statement 2 is SUFFICIENT

Cheers,
Brent
