Questions 1–1 review Unit 9 (20%). The remaining 4 questions assess the current unit. Show your work, simplify exact answers, label units, and explain when asked.
Quiz
Begin with the review questions, then continue through the current-unit questions.
- Previous unit review
Reading times in minutes are 7, 8, 8, 9, 9, 10. Draw a labeled dot plot. Check the number of dots.
- Current unit
A trapezoid has parallel bases 10 m and 14 m and perpendicular height 4 m. Sketch it and find its area.
- Current unit
A rectangular prism has edges 1, 3, and 4 cm. Sketch it and find its volume.
- Current unit
Reading times in minutes are 4, 5, 5, 6, 7, 16. Find the five-number summary and draw a labeled box plot. State the IQR.
- Current unit
Reading times in minutes are 5, 6, 6, 7, 8, 17. Write a summary with count, attribute, units, center, variability, shape, and a justified choice of measures.
Answers and reasoning
Reveal the teacher answer key
- 7: 1 dot; 8: 2 dots; 9: 2 dots; 10: 1 dot; n = 6
Each observation contributes one dot; stack repeated values at their number-line position.
- 48 m²
A = (10 + 14) × 4 ÷ 2 = 48.
- 12 cm³
B = 1 × 3 = 3 cm²; V = B × 4 = 12 cm³.
- (4, 5, 11/2, 7, 16); IQR 2 min
Box runs from 5 to 7, median line at 11/2, whiskers to 4 and 16.
- 6 observations of reading time in minutes. Median 13/2 min, IQR 2 min; right-skewed with a high value 17 min, so median/IQR resist that value.
Calculate the center and spread before interpreting them in context. Other accurate, justified summaries are acceptable.
