TEAS Exam Math Practice

Correct Answer: B

Rationale: To find the amount earned in 2 months, divide the total earned in 7 months by 7 to get the monthly amount. $15,036 / 7 = $2,148 earned per month. Then, multiply this monthly amount by 2 to find the earnings in 2 months: $2,148 * 2 = $4,296. Therefore, choice B ($4,296) is correct. Choices A, C, and D are incorrect because they do not follow the correct calculation steps and do not result in the accurate amount earned in 2 months.

Correct Answer: C

Rationale: To find the perimeter of the square, we first need to find the side length. Since the area of a square is side length squared (5625 = side length x side length), the side length is √5625 = 75 feet. The perimeter of a square is 4 times the side length, so 4 x 75 = 300 feet. Therefore, Melissa needs 300 feet of fencing. Summary: A) 75 feet - Incorrect. This is the side length, not the perimeter. B) 150 feet - Incorrect. This is half the perimeter. C) 300 feet - Correct. The perimeter of the square. D) 5,625 feet - Incorrect. This is the total area, not the perimeter.

Correct Answer: C

Rationale: To find the y-intercept, set x=0 in the equation 7y - 42x + 7 = 0: 7y - 42(0) + 7 = 0 7y + 7 = 0 7y = -7 y = -1 Thus, the y-intercept is (0, -1). Summary: A: Incorrect - The x-coordinate is not 1/6. B: Incorrect - The x-coordinate is not 6. C: Correct - The y-intercept is (0, -1). D: Incorrect - The x-coordinate is not -1.

Correct Answer: B

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: D

Rationale: The correct answer is D: The median is less than the mean. To find the median, first arrange the set in ascending order {5, 11, 18, 20, 37, 37, 60, 72, 90}. The median is the middle value, which is 37 here. To find the mean, add up all numbers and divide by the total count (sum/9). The mean is (60+5+18+20+37+37+11+90+72)/9 = 41.67. Since 37 (median) is less than 41.67 (mean), the statement is true. Other choices are incorrect because A is false as median ≠ mean, B is false since mean > mode, and C is false since mode ≠ median.
