Questions | Gre Math Prep

Finally, Emily encountered a permutation and combination question:

A company has 5 employees with salaries: $50,000, $60,000, $70,000, $80,000, and $90,000. What is the median salary?

A function f(x) = 2x^2 + 3x - 4 is defined for all real numbers. If f(x) = 5, what are the values of x?

The next question was a data analysis problem:

A committee of 3 people is to be formed from a group of 6 people. How many different committees are possible?

Emily recalled the Capital Asset Pricing Model (CAPM) formula: E(R) = Rf + β(E(Rm) - Rf). She plugged in the values and solved for E(Rm): 10% = 4% + 1.2(E(Rm) - 4%). After some algebra, she got E(Rm) = 8.33%.

Emily drew a diagram and applied the Pythagorean theorem: a^2 + b^2 = c^2. She plugged in the values: 6^2 + b^2 = 10^2. Solving for b, she got b = √(100 - 36) = √64 = 8 inches.

Emily had heard that the GRE was a tough exam, especially the math section. She had always been strong in math, but she knew that she needed to prepare thoroughly to get a good score. She started by taking a prep course and practicing with sample questions.
