A line passes through the points (2, 5) and (6, 13). What is the slope of the line?
Answer: 2
Slope = (13 − 5) / (6 − 2) = 8/4 = 2.
If the sales tax rate is 7.5%, what is the total cost of a $240 item after tax?
Answer: $258.00
Tax = 240 × 0.075 = $18; total = 240 + 18 = $258.
Which of the following is an example of a rational number that is NOT an integer?
Answer: 3/4
3/4 is a ratio of two integers and cannot be expressed as a whole number, making it a non-integer rational.
A box plot shows a data set with Q1 = 20, median = 30, Q3 = 45. What is the interquartile range (IQR)?
Answer: 25
IQR = Q3 − Q1 = 45 − 20 = 25.
Simplify: (x² · x⁵) / x³
Answer: x⁴
x² · x⁵ = x⁷; x⁷ / x³ = x⁴.
A student scored 78, 85, 91, and 82 on four tests. What score must the student earn on the fifth test to have an average of exactly 85?
Answer: 89
Total needed = 85 × 5 = 425; current total = 78+85+91+82 = 336; fifth score = 425 − 336 = 89.
Two parallel lines are cut by a transversal. If one interior angle measures 65°, what is the measure of its co-interior (same-side interior) angle?
Answer: 115°
Co-interior angles (also called consecutive interior angles) are supplementary, so 180° − 65° = 115°.
