TEAS Math Questions

Correct Answer: B

Rationale: To calculate the probability of consecutively pulling 2 orange blocks without replacement, we first find the probability of pulling 1 orange block, then the probability of pulling another orange block. 1. Probability of first orange block = 3/12 = 1/4 2. After removing 1 orange block, there are 2 orange blocks left out of 11 total blocks. 3. Probability of second orange block = 2/11 4. Multiply the probabilities: (1/4) * (2/11) = 2/44 = 1/22 5. Simplify the fraction: 1/22 = 2/44 = 3/66 = 3/55 Therefore, the correct answer is B (3/55) as it represents the probability of consecutively pulling two more orange blocks without replacement. Other choices are incorrect as they do not follow the correct calculation steps.

Correct Answer: C

Rationale: The correct answer is C: 6 hours. To calculate the total time taken, we first find the time taken for the first leg of the journey: 300 miles at 60 mph = 300/60 = 5 hours. Then, for the second leg: 200 miles at 80 mph = 200/80 = 2.5 hours. Adding these two times gives us 5 + 2.5 = 7.5 hours. Since there was a 30-minute break during the trip, we subtract this break time from the total, giving us 7.5 - 0.5 = 7 hours. Therefore, the correct answer is 6 hours. Choice A (5.5 hours) is incorrect because it does not account for the break time. Choice B (7 hours) is incorrect because it does not consider the total time with the break. Choice D (4.5 hours) is incorrect as it does not accurately calculate the total time

Correct Answer: C

Rationale: The correct answer is C (29). To find the range, we subtract the lowest number of flights from the highest number. Given that the choices are 20, 25, 29, and 32, the range would be 32 (highest) - 20 (lowest) = 12. Therefore, the number of flights per month must fall within this range, which is accurately represented by choice C (29). Choices A, B, and D are outside of this range and do not align with the calculation for finding the range, making them incorrect.

Correct Answer: B

Rationale: Veronica's total cost is the sum of the base price, surround sound system, and maintenance package: $40,210 + $3,015 + $5,218 = $48,443. This is the correct answer (B) as it calculates the total price accurately. Option A is incorrect as it only includes the base price. Option C is incorrect as it does not include the additional costs. Option D is incorrect as it only includes the base price without the additional expenses.

Correct Answer: B

Rationale: The correct answer is B: $1,280 more. In the financing plan, the total cost is $1,000 (down payment) + ($120 x 24 months) = $1,000 + $2,880 = $3,880. The difference between paying in cash and choosing the financing plan is $3,880 - $2,600 = $1,280. Therefore, the man would pay $1,280 more with the financing plan. A: $1,480 more - Incorrect because it miscalculates the total cost of the financing plan. C: $1,600 more - Incorrect as it overestimates the additional payment compared to the cash option. D: $2,480 more - Incorrect as it includes the total cost of the furniture itself, not just the additional cost of the financing plan.
