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: To simplify the given expression, combine like terms with the same variables. The expression 5x - 2y + 4x + y simplifies to 9x - y. Combine the x terms (5x + 4x = 9x) and the y terms (-2y + y = -y) to get 9x - y. This is the simplest form of the expression. The other choices are incorrect because they do not correctly combine the like terms or do not simplify the expression to its simplest form. Option B incorrectly subtracts 3y instead of y. Option C incorrectly adds 3y. Option D is not a simplified form of the expression as it lists x and y separately without combining like terms. So, the correct answer is A: 9x - y.

Correct Answer: A

Rationale: To determine how much money he puts into his house savings account each month, we subtract the rent from his total monthly budget. Since he pays $270 for rent, subtracting this from his total monthly budget gives $270. Therefore, he puts $90 into his house savings account each month. Option A is correct. Option B is incorrect as it represents the total rent amount. Options C and D are significantly higher than the rent amount, making them incorrect.

Correct Answer: B

Rationale: To determine the total liquid in the pot, we add the volume of chicken broth (4 containers x 410ml) to the volume of water (1 liter = 1000ml). Total liquid = (4 x 410) + 1000 = 1640 + 1000 = 2640ml = 2.64 liters. Therefore, the correct answer is B. Choice A is incorrect as it miscalculates the total liquid. Choice C and D are significantly higher than the correct answer, indicating an error in calculation.

Correct Answer: C

Rationale: To find the percentage of Dr. Lee's patients hospitalized after taking the antibiotic, we multiply the percentage of patients who developed an infection (30%) by the percentage of those hospitalized (5% of 30%): 30% * 5% = 1.5%. Therefore, 1.5% of all patients were hospitalized. The correct answer is C (15%). Summary: A (1.50%): This is incorrect because it miscalculates the percentage of patients hospitalized. B (5%): This is incorrect as it represents the percentage of patients that developed an infection and not those hospitalized. D (30%): This is incorrect as it represents the total percentage of patients developing an infection, not those hospitalized.
