Math Practice TEAS Test

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: 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 percentage of students with hazel or green eyes, add the number of students with hazel and green eyes (5+2=7). Then, divide this sum by the total number of students (7/30). Finally, multiply the result by 100 to convert it to a percentage (7/30 * 100 = 23%). Therefore, the correct answer is A (0.23). Choice B (0.3) is incorrect as it is not the accurate percentage of students with hazel or green eyes. Choice C (0.47) and choice D (0.77) are also incorrect as they do not represent the correct calculation of the percentage based on the given information.
