TEAS Test Math Prep

Correct Answer: B

Rationale: To maintain an overall average of at least 90, Dwayne needs to aim for the highest possible score. If he scores 98 on his next test, it will help balance any lower scores he may have received previously and ensure his average remains above 90. Choosing option B (98) is the best strategy as it allows for a margin of error while still meeting the target average. Options A, C, and D would not guarantee maintaining the required average as they are below 90.

Correct Answer: C

Rationale: The correct answer is C: 0.84. To convert a percentage to a decimal, you divide by 100. In this case, 84% divided by 100 equals 0.84. Choice A is incorrect as 0.042 is not equivalent to 84%. Choice B is incorrect as 84% is not the same as 0.84. Choice D is incorrect as 0.42 is not the correct decimal form of 84%. Therefore, the correct representation of 84% in decimal form is 0.84.

Correct Answer: D

Rationale: The correct answer is D: Pie chart. A pie chart is the most appropriate choice for displaying percentage data because it visually represents parts of a whole, making it easy to compare the time spent on different tasks during the workday. Each segment of the pie chart corresponds to a specific task percentage, allowing Juan to quickly see the breakdown of his time. Explanation of Incorrect Choices: A: Line plot - Line plots are used to show trends over time or continuous data points, not ideal for comparing percentages of different tasks. B: Bar graph - Bar graphs are suited for comparing categories or discrete data points, not the best choice for displaying percentages. C: Line graph - Line graphs are typically used to show trends and relationships between variables, not suitable for displaying percentages of different tasks.

Correct Answer: C

Correct Answer: A

Rationale: The correct answer is A: 2 x 4 x 4 x 2. To find the value of 6 x 12, we can break it down into simpler multiplication. 6 x 12 = 6 x (4 x 3) = (2 x 3) x (4 x 3) = 2 x 4 x 4 x 2. This shows that the value of 6 x 12 is indeed equal to 2 x 4 x 4 x 2. Explanation for why other choices are incorrect: B: 7 x 4 x 3 does not equal 6 x 12. C: 6 x 6 x 3 equals 108, not 72 (6 x 12). D: 3 x 3 x 4 x 2 equals 72, but the order of multiplication is not the same as in 6 x 12, making it incorrect.
