  1. A line passes through points (2, 5) and (6, 13). What is the slope of the line?

    Answer: 2

    Slope = (13−5)/(6−2) = 8/4 = 2.

  2. A data set has a mean of 45 and a standard deviation of 5. Which value is most likely an outlier?

    Answer: 62

    62 is (62−45)/5 = 3.4 standard deviations from the mean, far outside the typical ±2 range.

  3. Solve the inequality: −3x + 6 > 15

    Answer: x < −3

    Subtract 6: −3x > 9; divide by −3 and flip the inequality: x < −3.

  4. A 500 mL bag of saline must infuse at a rate of 40 mL/hr. How many hours and minutes will the infusion take?

    Answer: 12 hr 30 min

    500 ÷ 40 = 12.5 hours = 12 hours and 30 minutes.

  5. What is the value of 4! (4 factorial)?

    Answer: 24

    4! = 4 × 3 × 2 × 1 = 24.

  6. A cylindrical container has a radius of 3 cm and a height of 10 cm. What is its volume? (Use π ≈ 3.14)

    Answer: 282.6 cm³

    V = πr²h = 3.14 × 9 × 10 = 282.6 cm³.

  7. A nurse earns $34.50 per hour and receives time-and-a-half for overtime (over 40 hours). How much does she earn in a week where she works 46 hours?

    Answer: $1,587.00

    Regular pay: 40 × $34.50 = $1,380; overtime pay: 6 × $51.75 = $310.50; total = $1,587.00... wait: 6 × 51.75 = 310.50; 1380+310.50=1690.50.
