Q1 · Difficulty 1/3

The population of Jamaica in 2023 was estimated as 2.825 × 10⁶. What is this number written as an ordinary number?

  1. 282 500
  2. 2 825 000
  3. 28 250 000
  4. 282 500 000
Show answer & explanation
✓ Answer: B — 2 825 000
Award 1 mark for 2 825 000. The power of 6 means the decimal point moves 6 places to the right: 2.825 × 10⁶ = 2 825 000. A is incorrect because the decimal point moved only 5 places. C is incorrect because the decimal point moved 7 places. D is incorrect because the decimal point moved 8 places.
Q2 · Difficulty 1/3

A fisherman in Trinidad records his daily catch using a numbering system. He writes the number 34₅. What is this number in base ten?

  1. 12
  2. 17
  3. 19
  4. 34
Show answer & explanation
✓ Answer: C — 19
Award 1 mark for: 3×5 + 4×1 = 15 + 4 = 19. A is incorrect — this is the sum of digits only. B is incorrect — this uses base 4 instead of base 5. D is incorrect — this assumes the number is already in base ten.
Q3 · Difficulty 1/3

Which number is a multiple of 7?

  1. 27
  2. 42
  3. 50
  4. 16
Show answer & explanation
✓ Answer: B — 42
42 = 7 × 6.
Q4 · Difficulty 1/3

A hurricane in Barbados produced wind speeds measured at 67.348 m/s. What is this value rounded to 1 decimal place?

  1. 67.3 m/s
  2. 67.4 m/s
  3. 67 m/s
  4. 70 m/s
Show answer & explanation
✓ Answer: A — 67.3 m/s
Award 1 mark for 67.3 m/s. Rounding to 1 decimal place requires examining the second decimal place (4). Since 4 < 5, the first decimal place remains as 3. B is incorrect because 4 in the second decimal place does not cause rounding up. C is incorrect because it shows no decimal places. D is incorrect because it is rounded to the nearest ten.
Q5 · Difficulty 1/3

Express 1/(3⁴) using a negative exponent.

  1. 3⁻⁴
  2. -3⁴
  3. 3⁴
  4. (-3)⁴
Show answer & explanation
✓ Answer: A — 3⁻⁴
Award 1 mark for correct expression. The negative exponent law states 1/aⁿ = a⁻ⁿ. B places the negative sign on the base, not the exponent. C is the reciprocal of the correct answer. D incorrectly applies the negative to the base.
Q6 · Difficulty 1/3

What is (-3) × (-4)?

  1. -12
  2. 12
  3. -7
  4. 7
Show answer & explanation
✓ Answer: B — 12
Negative × negative = positive. 3 × 4 = 12.
Q7 · Difficulty 1/3

The manager of a cricket club in Barbados collected data on the ages of 50 club members. Which of the following would be the MOST appropriate method of data collection?

  1. Observation
  2. Questionnaire
  3. Experiment
  4. Published statistics
Show answer & explanation
✓ Answer: B — Questionnaire
Award 1 mark for identifying questionnaire as the most appropriate method for collecting personal data from a defined group. A is incorrect — observation cannot accurately determine ages. C is incorrect — an experiment is used to test hypotheses, not collect personal data. D is incorrect — published statistics would not provide specific data for this club.
Q8 · Difficulty 1/3

A farmer in St. Vincent recorded the mass, in kg, of 50 pumpkins harvested from his field. The smallest pumpkin had a mass of 2.3 kg and the largest had a mass of 8.7 kg. What is the range of the masses?

  1. 6.4 kg
  2. 8.7 kg
  3. 11.0 kg
  4. 5.5 kg
Show answer & explanation
✓ Answer: A — 6.4 kg
4 kg. Award 1 mark for correct calculation: Range = largest value − smallest value = 8.7 − 2.3 = 6.4 kg. B is incorrect — this is only the maximum value, not the range. C is incorrect — this adds the values instead of subtracting. D is incorrect — calculation error.
