Part 2: Written Response
- The temperature at midnight was −6°F, and it rose to 9°F by noon. Plot both temperatures on a number line and find the change. Explain how absolute value helps.
- Find the mean, median, and range of these quiz scores: 7, 9, 10, 6, 8, 10. Then explain which measure of center best describes the data and why.
- D — 50 miles per hour 150 ÷ 3 = 50 miles per hour.
- C — 42 3.5 × 12 = 42 inches.
- C — 2:3 Divide both terms by 3: 6:9 = 2:3.
- B — 40 25 ÷ 5 = 5 minutes per km; 5 × 8 = 40.
- A — 24 0.30 × 80 = 24.
- C — 24 Multiples of 8: 8, 16, 24. 24 is the first divisible by 6.
- C — 32 Multiply both by 10: 96 ÷ 3 = 32.
- C — 7 21/4 ÷ 3/4 = 21/3 = 7.
- C — 12(3 + 4) GCF is 12: 12 × 3 = 36 and 12 × 4 = 48.
- B — 12 Factors common to both: 1, 2, 3, 4, 6, 12. Greatest is 12.
- C — −1.5 −2 < −1.5 < −1.
- C — (4, 2) Reflecting across the x-axis changes the sign of the y-coordinate.
- A — −5 > −8 −5 is to the right of −8 on a number line.
- D — 11°F −4 + 15 = 11.
- C — The diver is 30 feet below sea level. Negative elevation means below sea level.
- B — 8t + 3 Each ticket adds $8, and the $3 fee is charged once.
- A — 2n − 5 Twice n is 2n; five less than that is 2n − 5.
- D — 6(3m + 4) Factor out the GCF 6: 6 × 3m = 18m and 6 × 4 = 24.
- A — 3a + 5b Combine like terms: 4a − a = 3a and 3b + 2b = 5b.
- D — 20 Exponent first: 8; then 4 × 3 = 12; 8 + 12 = 20.
- A — n = 13.5 Add 3.5 to both sides: 10 + 3.5 = 13.5.
- A — y = 9 Divide both sides by 6: 54 ÷ 6 = 9.
- D — Yes, because 3(5) − 4 = 11 Substitute: 3 × 5 = 15 and 15 − 4 = 11.
- B — x = 28 Multiply both sides by 4: 7 × 4 = 28.
- C — 6 6 + 7 = 13, and 13 > 12. Note 5 + 7 = 12 is not greater than 12.
- C — 8 Q1 = 4 and Q3 = 12, so IQR = 12 − 4 = 8.
- B — How many hours do students in my class sleep? A statistical question expects answers that vary.
- A — 30 square units A = 1/2 × b × h = 1/2 × 10 × 6 = 30.
- C — 54 square inches 6 faces × (3 × 3) = 6 × 9 = 54.
- C — 6 cubic feet V = l × w × h = 3 × 4 × 1/2 = 6.
Written Response — Look-Fors
- Change of 15 degrees; correct placement on number line; explains distance as |−6| + |9| or 9 − (−6).
- Mean 50/6 ≈ 8.33, median 8.5, range 4; reasoned choice of center (data has no extreme outliers).
