TEAS 7 Math Practice Test

Correct Answer: B

Rationale: The correct answer is B because it accurately describes the rate of change as the snow melting by 5 centimeters every day. This statement represents a consistent decrease in the snow level over time. Choice A is incorrect as it implies a higher rate of melting than what is described. Choice C is incorrect as it describes an increase rather than a decrease. Choice D is also incorrect as it describes an increase instead of the intended decrease in snow level. Therefore, choice B is the most accurate representation of the rate of change in this scenario.

Correct Answer: B

Rationale: To find the approximate number of people who voted for the proposition, we multiply the town's population by the percentage that voted: 51,623 * 9.5% = 51,623 * 0.095 = 4,904. Therefore, approximately 5,000 people voted for the proposition. Choice A (3,000) is too low because 9.5% of the population would result in more voters. Choice C (7,000) is too high because it exceeds the calculation based on the given percentage. Choice D (10,000) is also too high as it overestimates the number of voters based on the percentage provided.

Correct Answer: D

Rationale: The correct answer is D: 0.16%. To find the percentage equivalent of a decimal, we multiply the decimal by 100. So, 0.0016 x 100 = 0.16%. Choice A (16%) is incorrect because it represents the decimal as a whole number, not a percentage. Choice B (160%) is incorrect as it incorrectly multiplies the decimal by 1000 instead of 100. Choice C (1.60%) is incorrect as it incorrectly places the decimal point in the wrong position, resulting in an incorrect percentage value.

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: 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.
