Math Practice TEAS Test

Correct Answer: A

Rationale: The correct answer is A because in a fraction, the numerator is the number written on the top, representing the parts being considered, while the denominator is the number written on the bottom, representing the total number of equal parts the whole is divided into. Choices B, C, and D are incorrect because they do not align with the standard mathematical convention where the numerator is always placed above the denominator in a fraction representation. B, C, and D provide misleading and incorrect information regarding the position and role of the numerator and denominator in a fraction.

Correct Answer: A

Rationale: The correct answer is A: x + 4 = 5/6y - 2. To break it down step-by-step: 1. "Four more than a number" translates to x + 4. 2. "2 less than 5/6 of another number" translates to 5/6y - 2. 3. Combining the two expressions gives x + 4 = 5/6y - 2, which represents the given relationship accurately. In summary, choice A is correct because it correctly captures the relationship described in the question. Choices B, C, and D are incorrect because they do not accurately represent the relationship between the two numbers given in the question.

Correct Answer: A

Rationale: The correct answer is A: This is a linear association with a positive correlation. This scatterplot shows a clear pattern where the data points form a straight line that slopes upward from left to right, indicating a positive correlation. Positive correlation means that as one variable increases, the other variable also tends to increase. In this case, the data points are clustered around the line, showing a strong linear relationship. Choices B, C, and D are incorrect because the scatterplot does not exhibit a negative correlation, nonlinear association, or no association. The linear pattern with a positive slope in the scatterplot supports the selection of choice A as the best description of the data.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Sum of two odd numbers is always even (odd + odd = even). 2. Sum of two even numbers is always even (even + even = even). 3. Sum of an odd number and an even number is always odd (odd + even = odd). Therefore, the sum of two odd numbers, two even numbers, an odd number, and an even number would be Even + Even + Odd + Odd = Even. Summary: Choice A is correct as it follows the rules of adding odd and even numbers. Choices B, C, and D are incorrect as they incorrectly state the outcomes of adding odd and even numbers.

Correct Answer: B

Rationale: The correct answer is B: 16 ounces. There are 16 ounces in a pound because this is the standard conversion rate between ounces and pounds. To arrive at this conversion, we can use the fact that 1 pound is equal to 16 ounces. Therefore, if you have 1 pound and you want to convert it to ounces, you would multiply 1 pound by 16 ounces/pound, which gives you 16 ounces. Summary of other choices: A: 8 ounces - This is incorrect because 8 ounces is half of a pound, not the full conversion rate. C: 32 ounces - This is incorrect because 32 ounces is actually equivalent to 2 pounds, not 1 pound. D: 12 ounces - This is incorrect as it is not the standard conversion rate between ounces and pounds.
