ATI TEAS Math Practice Test

Correct Answer: A

Rationale: The correct answer is A: $2,500. To calculate the total monthly earnings, first determine the commission earned on sales: $5,000 * 3% = $150. Add this to the base salary of $2,000: $2,000 + $150 = $2,150. Therefore, the total monthly earnings will be $2,150.

Correct Answer: B

Rationale: The correct answer is B: The grades students received. The dependent variable is the outcome that is being measured or observed in response to changes in the independent variable. In this research study, the grades students received are dependent on the number of hours spent studying, which is the independent variable. The grades received will vary based on the amount of time spent studying. Choices A, C, and D are incorrect because they are not the outcome or response variable being measured in relation to the independent variable of hours spent studying. A is the independent variable, C is not a variable in this context, and D is not directly related to the outcome being measured.

Correct Answer: D

Rationale: To arrange the numbers from least to greatest, we convert them to decimals or find a common denominator. Converting to decimals, we get: 7/3 = 2.33, 9/2 = 4.5, 10/9 = 1.11, 7/8 = 0.875. Therefore, the correct order is 7/8 < 10/9 < 7/3 < 9/2. Choice D is correct as it follows this order. Choices A, B, and C are incorrect as they do not reflect the correct ascending sequence.

Correct Answer: C

Rationale: To earn more than 96 points, Mathew needs to answer at least 97 points out of 120 (40 questions * 3 points each). This means he can only get a maximum of 23 questions wrong (120 - 97 = 23). So, Mathew can answer up to 7 questions incorrectly (23/3 = 7.67, rounded down to 7) and still qualify for varsity sports. Therefore, the correct answer is C: 0 ≤ x < 8, as Mathew can answer 0 to 7 questions incorrectly and still meet the eligibility requirement. Choices A, B, and D are incorrect because they do not accurately reflect the maximum number of questions Mathew can answer incorrectly based on the total points needed for eligibility.

Correct Answer: B

Rationale: The correct answer is B: Group A is positively skewed, while Group B is approximately normal. This is because in a positively skewed distribution, the tail of the graph extends to the right, indicating a higher frequency of lower values. In the double bar graph provided, Group A has a longer bar on the left side, suggesting a higher concentration of lower values, which is indicative of positive skewness. Group B, on the other hand, shows a more symmetrical distribution, with bars of similar length on both sides, implying an approximately normal distribution. Other choices are incorrect because: A: Group A is not negatively skewed, as it has a longer left tail. C: Group A is not approximately normal, as it shows characteristics of positive skewness. D: Group B is not positively skewed, as it does not have a longer right tail.
