Practice Question
Emma measured the height of her laptop screen. She reported the height as 8 inches, accurate to the nearest inch. The actual height of the screen must be:
Answer Choices
- A: at least 7.5 inches and less than 8.5 inches
- B: at least 7.9 inches and less than 8.1 inches
- C: at least 7.99 inches and less than 8.01 inches
- D: at least 8 inches
- E: exactly 8 inches
Correct Answer: A
Rationale: Rounding to the nearest inch means the actual height h satisfies 7.5 ≤ h < 8.5. Options: A matches; B (7.9 to 8.1), C (7.99 to 8.01) are too narrow; D (at least 8) excludes below 8; E (exactly 8) is too restrictive.
