Answer 1

1) 112 cards — rate is +16 cards per year (32 → 48 → 80), so 80 + 2·16 = 112.

2) Mean = 74.8 — (sum 748 ÷ 10). This indicates an average grade; the student does okay but may struggle at times.

3) 20% — 10 is 10/50 = 0.2 = 20%.

4) 1.35 meters — 135 cm = 135/100 m = 1.35 m.

5) 53 — range = max(98) − min(45) = 53.
