Question 1 of 5
What is the length of the unknown leg of a right triangle that has one leg measuring 9 feet and a hypotenuse of 19 feet? (Round to the nearest tenth.)
Correct Answer: A
Rationale: To find the length of the unknown leg, we can use the Pythagorean theorem: a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse of a right triangle. Given a = 9 feet and c = 19 feet, we can solve for b: 9^2 + b^2 = 19^2 81 + b^2 = 361 b^2 = 280 b ≈ √280 ≈ 16.7 feet Therefore, the correct answer is A (16.7 feet). Choice B (16.0 feet) is incorrect as it does not account for rounding to the nearest tenth. Choice C (17.4 feet) and choice D (8.4 feet) are incorrect as they do not match the calculated value.
Question 2 of 5
A new physician saw 841 clients during the first year of practice and 1072 clients during the second year of practice. Which of the following represents the approximate percentage increase in client volume?
Correct Answer: B
Rationale: To calculate the percentage increase, subtract the initial value from the final value, then divide by the initial value and multiply by 100. Percentage Increase = [(1072-841)/841] x 100 ≈ 27% Therefore, choice B (27%) is the correct answer as it represents the approximate percentage increase in client volume. Choice A (22%) is incorrect because it does not accurately reflect the calculated percentage increase. Choice C (127%) is incorrect as it is way too high and does not align with the actual increase. Choice D (78%) is incorrect as it is also significantly off from the calculated percentage increase.
Question 3 of 5
What is the equivalent weight in pounds for 45 kg? (1 kg = 2.2 lbs)
Correct Answer: C
Rationale: To convert 45 kg to pounds, multiply by the conversion factor 2.2 lbs/kg. So, 45 kg * 2.2 lbs/kg = 99 lbs. Therefore, the correct answer is C. Choice A (120 lbs) is incorrect as it is not the result of the conversion calculation. Choice B (89 lbs) is also incorrect as it does not match the conversion result. Choice D (90 lbs) is incorrect because the correct equivalent weight is 99 lbs, not 90 lbs.
Question 4 of 5
What defines a proper fraction versus an improper fraction?
Correct Answer: A
Rationale: The correct answer is A because in a proper fraction, the numerator (top number) is less than the denominator (bottom number). This indicates a fraction that is less than 1. In an improper fraction, the numerator is greater than the denominator, representing a fraction that is equal to or greater than 1. Choice B is incorrect because it reverses the definitions of proper and improper fractions. Choice C is incorrect because it suggests that a fraction is proper if the numerator is equal to the denominator, which is incorrect. Choice D is incorrect because it defines an improper fraction as having a numerator equal to the denominator, which is not the case.
Question 5 of 5
Which of the following relationships represents no correlation between two variables?
Correct Answer: A
Rationale: The correct answer is A because it describes a scenario with no correlation between two variables. In this case, as class attendance decreases, the overall grade remains the same, indicating that there is no relationship between attendance and grade. This lack of change in grade despite attendance levels demonstrates no correlation between the variables. Choice B is incorrect because it shows a negative correlation between exercise hours and weight gain. Choice C is incorrect as it represents a negative correlation between miles driven and gasoline in the tank. Choice D is incorrect as it illustrates a positive correlation between water intake and plant growth rate.
