Math Practice TEAS Test Questions
Question 1 of 5
Solve for x: x + 5 = x - 3.
Correct Answer: A
Rationale: To solve for x in the equation x + 5 = x - 3, we need to isolate x. Subtract x from both sides to get 5 = -3. This is not possible, so the equation has no solution. Therefore, the correct choice is A: x = -5. This is because when x = -5, -5 + 5 = -5 - 3 simplifies to 0 = -8, which is false. Choices B, C, and D are incorrect because they do not satisfy the original equation when substituted back in.
Question 2 of 5
In Mrs. McConnell's classroom, there are 14 students with brown eyes and 2 students with green eyes. What is the ratio of students with brown eyes to students with green eyes?
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.
Question 3 of 5
A driver drove 305 miles at 65 mph, stopped for 15 minutes, then drove another 162 miles at 80 mph. How long was the trip?
Correct Answer: B
Rationale: To calculate the total trip duration, first find the time taken for the first leg (305 miles at 65 mph = 305/65 = 4.69 hours). Then factor in the 15-minute stop (0.25 hours). Finally, calculate the time for the second leg (162 miles at 80 mph = 162/80 = 2.03 hours). Add all times together (4.69 + 0.25 + 2.03 = 6.97 hours), which is closest to choice B (6.69 hours). This is the correct answer as it considers the time for each leg and the stop accurately. Other choices are incorrect because they do not accurately calculate the total trip duration.
Question 4 of 5
Which unit of measurement is larger, inches or centimeters?
Correct Answer: A
Rationale: The correct answer is A: Inches are larger. This is because one inch is equivalent to 2.54 centimeters. Therefore, when comparing the two units, inches are larger in size. Centimeters are smaller units of measurement compared to inches. Choice B is incorrect as centimeters are smaller. Choice C is incorrect because they are not the same size. Choice D is incorrect as the relationship between inches and centimeters is fixed with 1 inch being larger than 1 centimeter.
Question 5 of 5
Given a double bar graph, which statement is true about the distributions of Group A and Group B?
Correct Answer: B
Rationale: The correct answer is B: Group A is positively skewed, Group B is normal. In a double bar graph, skewness can be identified based on the distribution of bars. 1. Positive skewness means the tail of the distribution extends to the right, indicating a higher frequency of lower values. 2. Looking at Group A, if the bars are concentrated on the left side with a few bars extending to the right, it suggests positive skewness. 3. Group B being normal implies a symmetrical distribution with no skewness. Therefore, B is correct as it correctly describes the skewness of Group A and Group B based on the given information. Summary: A: Incorrect - Group A is positively skewed, not negatively skewed. C: Incorrect - Group B is normal, not neutral. D: Incorrect - Group A is positively skewed, not normal.
