TEAS 7 Math Practice Test

Correct Answer: C

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: A

Rationale: The correct answer is A: $90. Given the ratio of 1:3 for house savings to rent, and the rent of $270 per month, we can set up a proportion. Let x be the amount saved for the house. The ratio equation is: x/270 = 1/3. Cross-multiplying gives x = 270/3 = $90. Therefore, the roommate saves $90 each month. Choice B: $270 is incorrect because that is the amount of rent paid, not the amount saved for the house. Choice C: $730 is incorrect as it is not derived from the given ratio and rent amount. Choice D: $810 is incorrect as it is also not in line with the ratio and rent information provided.

Correct Answer: C

Rationale: To determine the number of male patients not overweight as children, we first find the total number of male patients by calculating 30% of 100, which equals 30. Then, we find the number of overweight men (10% of 30), which is 3. Subtracting 3 from the total number of male patients gives us the number of male patients not overweight as children, which is 27 (30 - 3 = 27). Therefore, the correct answer is C. Option A is too low, B does not account for the overweight men, and D is too high based on the calculations.

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: 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.
