TEAS 7 Math Practice Test

Correct Answer: C

Rationale: To find the cost of one box of crackers, we set up a system of equations. Let x be the cost of one container of yogurt and y be the cost of one box of crackers. From the given information, we have: 4x + 3y = 9.55 2x + 2y = 5.90 Solving the system of equations, we find x = 1.45 and y = 2.25. Therefore, one box of crackers costs $2.25, making choice C the correct answer. Incorrect choices: A: $1.75 - Incorrect because it doesn't match the calculated cost. B: $2.00 - Incorrect, as it does not align with the calculated cost. D: $2.50 - Wrong, as it does not correspond to the calculated value.

Correct Answer: C

Rationale: The correct answer is C because it asks for the greatest percentage of a specific group among the staff at Hospital X and Hospital Y. This is a broader group compared to the other choices, making it more likely to have a higher percentage. Choices A, B, and D are specific to Hospital X or Y only, limiting the pool of individuals being considered and reducing the likelihood of having the highest percentage. Choice C considers the combined staff of two hospitals, increasing the pool of individuals and making it more probable to have a higher percentage of doctors among the staff.

Correct Answer: B

Rationale: Correct Answer: B ($48,443) Rationale: To find the total price of Veronica's new car, add the base price ($40,210) to the cost of the surround sound system ($3,015) and the maintenance package ($5,218). Therefore, $40,210 + $3,015 + $5,218 = $48,443. Summary of other choices: A: $50,210 - Incorrect as it only includes the base price of the car. C: $43,225 - Incorrect as it only includes the base price and the maintenance package. D: $40,210 - Incorrect as it only includes the base price of the car.

Correct Answer: C

Rationale: The correct answer is C because in a negatively skewed distribution, the tail of the histogram extends to the left, indicating that there are more data points on the right side. In Group B, the histogram is negatively skewed, meaning it has a higher mean than Group A. Option A is incorrect because Group A is positively skewed, not negatively skewed. Option B is incorrect because Group A has a lower mean than Group B. Option D is incorrect because Group B has a higher mean than Group A due to its negatively skewed distribution.

Correct Answer: A

Rationale: To simplify the expression, you first add the numbers together: 1.034 + 0.275 = 1.309. Then, subtract 1.294 from the result: 1.309 - 1.294 = 0.015. Therefore, the correct answer is A (0.015). Choices B, C, and D are incorrect as they do not match the calculated result of 0.015.
