Question 1 of 5

Translate the phrase 'Five less than twice the number' into a mathematical expression.

Correct Answer: B

Rationale: To translate 'Five less than twice the number' into a mathematical expression, you first calculate twice the number (2x) and then subtract 5 from it. This gives you 2x-5. Therefore, choice B, 2x-5, accurately represents the mathematical expression for 'Five less than twice the number.' The phrase 'Five less than' implies subtraction, and 'twice the number' is represented by 2x. Thus, when you subtract 5 from twice the number, the correct expression is 2x-5.

Question 2 of 5

Which of the following relationships represents a positive correlation between two variables?

Correct Answer: A

Rationale: A positive correlation means both variables increase together. As the amount of water a plant receives increases, the plant's health typically improves.

Question 3 of 5

What is the area of a circle with a diameter of 16 inches in terms of pi (π)?

Correct Answer: B

Rationale: To calculate the area of a circle, you use the formula A = πr^2, where r is the radius of the circle. Since the diameter is given as 16 inches, the radius (r) is half of that, which is 8 inches. By substituting r = 8 into the formula, you calculate the area as A = π(8)� = 64π square inches. Therefore, the correct answer is 64π in squared (Choice B). This calculation is derived from the concept of the radius being half of the diameter in a circle formula.

Question 4 of 5

What is the equivalent weight in pounds of 50 kg? (1 kg = 2.2 lb)

Correct Answer: A

Rationale: To convert kilograms to pounds, you multiply by the conversion factor 2.2 (1 kg = 2.2 lb). Therefore, 50 kg * 2.2 lb/kg = 110 lb. The correct answer is A because 50 kg is equivalent to 110 lb when using the conversion factor.

Question 5 of 5
