Math Practice TEAS Test

Correct Answer: A

Rationale: The correct answer is A because a histogram represents continuous data with no gaps between bars, while a bar graph displays discrete data with gaps between bars. Option B is incorrect because both graphs can display frequency. Option C is incorrect as both can be used for comparison. Option D is incorrect as both can include labels.

Correct Answer: A

Rationale: To find the ratio of students with brown eyes to students with green eyes, we divide the number of students with brown eyes by the number of students with green eyes. In this case, 14 students with brown eyes divided by 2 students with green eyes equals 7. Therefore, the correct ratio is 7:1 (choice A). Choice B is incorrect as it represents the ratio of 7:2, which is the reverse of the given scenario. Choice C is incorrect as it shows the ratio of 14:2, which can be further simplified to 7:1. Choice D is incorrect as it incorrectly states the ratio as 14:1, which is not the case based on the information provided.

Correct Answer: A

Rationale: The correct answer is A: 1328.35. To calculate the total cost, we first add up the costs of airfare, hotel (5 nights), sightseeing, and meals. Next, we calculate the cost of additional hotel nights after the 10% discount. Finally, we sum up all the costs to get the total amount Margery will spend. The other choices are incorrect because they do not follow the correct calculation process or include the discount on additional hotel nights.

Correct Answer: B

Rationale: The correct answer is B: 1,000 mm. This is because there are 1,000 millimeters in a meter. The metric system is based on units of 10, so to convert meters to millimeters, you multiply by 1,000 (10 x 10 x 10). Therefore, 1 meter equals 1,000 millimeters. Choice A (100 mm) is incorrect as it represents centimeters, not millimeters. Choice C (10,000 mm) and Choice D (100,000 mm) are incorrect because they are multiples of 1,000 and would be equivalent to 10 meters and 100 meters respectively, not millimeters.

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.
