TEAS Test Practice Math

Correct Answer: B

Rationale: The correct answer is B: Group Z, Group Y, Group X. This is because Group Z has the largest number of doctors, followed by Group Y, then Group X. To determine this, we need to compare the order of each group's size. Group Z > Group Y > Group X in terms of the number of doctors. Choice A (Group X, Group Y, Group Z) is incorrect because it lists the groups in ascending order of doctor numbers, which is opposite to the correct order. Choice C (Group Z, Group X, Group Y) is incorrect as it incorrectly places Group X before Group Y. Choice D (Group Y, Group X, Group Z) is incorrect because it lists the groups in ascending order, which is the opposite of the correct order.

Correct Answer: A

Rationale: The mean is the sum of all values divided by the number of values, while the median is the middle value when data is ordered. In a skewed distribution, the mean is pulled towards the tail, making it less than the median. Therefore, statement A is true. Explanation: A: The mean is less than the median - True, as explained above. B: The mode is greater than the median - Not necessarily true. Mode can be less than or equal to the median. C: The mode is less than the mean, median, and range - Not always true. Mode can be greater than the mean or median. D: The mode is equal to the range - Incorrect, mode and range are unrelated statistical measures.

Correct Answer: B

Rationale: The correct answer is B: $86,666.67. To calculate this, divide the total operating expenses ($130,000) by 3, as a general guideline is that one-third of operating expenses typically go towards employee wages and benefits. $130,000 / 3 = $43,333.33. However, this only represents the wages portion, and benefits are typically an additional 50% of wages, making the total amount spent on wages and benefits $43,333.33 + ($43,333.33 * 0.5) = $86,666.67. Choice A: $43,333.33 - This only represents the wages portion and does not include benefits. Choice C: $52,000.00 - This amount does not account for benefits and is not calculated correctly. Choice D: $78,000.00 - This amount is only the wages portion and does not include benefits.

Correct Answer: C

Rationale: The correct answer is C: $36. The question states that each roommate contributes $12. Therefore, to find the total amount, we multiply $12 by the number of roommates (3 roommates x $12 = $36). This calculation gives us the estimated total amount of money the roommates used to purchase the gift. Choice A: $34 is incorrect because it does not account for all three roommates contributing $12 each. Choice B: $35 is incorrect as it also does not consider all three roommates contributing $12 each. Choice D: $37 is incorrect because it exceeds the total amount that can be obtained by multiplying $12 by 3.

Correct Answer: C

Rationale: To calculate the percent decrease in snowfall: 1. Find the difference in snowfall between the two winters: 6 - 3 = 3 inches. 2. Divide the difference by the initial amount: 3 / 6 = 0.5. 3. Multiply the result by 100 to get the percentage decrease: 0.5 * 100 = 50%. Therefore, the correct answer is C (41.00%) as it is the closest rounded percentage to the calculated 50% decrease. Other choices are incorrect as they do not align with the calculated decrease percentage.
