HiSET Practice Test Math 2

Question 1

Solve for x: 3x − 7 = 14

Accepted Answer

x = 7

Answer

Add 7 to both sides: 3x = 21. Divide both sides by 3: x = 7.

Question 2

A data set contains the values: 4, 7, 7, 9, 12, 15. What is the median?

Accepted Answer

8

Answer

With 6 values, the median is the average of the 3rd and 4th values. Sorted: 4, 7, 7, 9, 12, 15. The 3rd and 4th values are 7 and 9. (7 + 9) ÷ 2 = 8.

Question 3

What is the slope of a line passing through the points (2, 5) and (6, 13)?

Accepted Answer

2

Answer

Slope = (y₂ − y₁) / (x₂ − x₁) = (13 − 5) / (6 − 2) = 8 / 4 = 2.

Question 4

A circle has a radius of 6 cm. What is its area? (Use π ≈ 3.14)

Accepted Answer

113.04 cm²

Answer

Area = π × r² = 3.14 × 6² = 3.14 × 36 = 113.04 cm².

Question 5

Which of the following is equivalent to 2³ × 2⁴?

Accepted Answer
