TEAS Test Practice Math

Correct Answer: D

Rationale: To determine the percentage of rainfall received in October, divide the total rainfall received in October by the total rainfall during the timeframe and multiply by 100. Let's say the total rainfall in October is 177 mm and the total rainfall during the timeframe is 1000 mm. (177/1000) * 100 = 17.7%. So, the correct answer is D. Choices A, B, and C are incorrect as they do not accurately represent the percentage of rainfall received in October based on the given data.

Correct Answer: A

Rationale: To find the actual distance in miles, multiply the map distance by the scale factor. 3.2 inches * 45 miles/inch = 144 miles. Choice A is correct because it correctly applies the scale factor. Choices B, C, and D are incorrect because they do not properly calculate the actual distance using the scale provided on the map.

Correct Answer: A

Rationale: The mean is the sum of all values divided by the number of values, while the median is the middle value when data is ordered. In a skewed distribution, the mean is pulled towards the tail, making it less than the median. Therefore, statement A is true. Explanation: A: The mean is less than the median - True, as explained above. B: The mode is greater than the median - Not necessarily true. Mode can be less than or equal to the median. C: The mode is less than the mean, median, and range - Not always true. Mode can be greater than the mean or median. D: The mode is equal to the range - Incorrect, mode and range are unrelated statistical measures.

Correct Answer: B

Rationale: To determine the total liquid in the pot, we add the volume of chicken broth (4 containers x 410ml) to the volume of water (1 liter = 1000ml). Total liquid = (4 x 410) + 1000 = 1640 + 1000 = 2640ml = 2.64 liters. Therefore, the correct answer is B. Choice A is incorrect as it miscalculates the total liquid. Choice C and D are significantly higher than the correct answer, indicating an error in calculation.

Correct Answer: D

Rationale: To calculate the percentage difference, we need to find the percentage increase from City X to City Y. Let's assume City X has 100 staff members, with 40 females, making 40% female. In City Y, there are 120 staff members, with 60 females, making 50% female. The percentage difference is (50% - 40%) / 40% = 0.25 or 25%. Therefore, there are 25% more female staff in City Y compared to City X, which is equivalent to 20% of the female staff in City X. So, the correct answer is D (20%). Choice A (5%), B (10%), and C (15%) are incorrect as they do not accurately reflect the 20% increase in female staff members between the two cities.
