Practice Math TEAS TEST

Correct Answer: C

Rationale: The correct answer is C: Bell-shaped. This is because a symmetric distribution with a single peak is characteristic of a bell-shaped distribution, also known as a normal distribution. In a bell-shaped distribution, the data is evenly distributed around the mean, creating a symmetrical pattern. Choice A (Uniform) is incorrect because a uniform distribution would show an equal frequency of weights across all values, without a distinct peak. Choice B (Bimodal) is incorrect because a bimodal distribution would have two distinct peaks, indicating two separate groups of weights rather than a single peak. Choice D (Skewed right) is incorrect because a right-skewed distribution would have a tail extending to the right, with the majority of weights concentrated on the left side, not centered around a single peak.

Correct Answer: A

Rationale: The correct answer is A: 3x-12. To express 'Twelve less than thrice a number,' we first represent 'a number' as x. Then 'thrice a number' is 3x. Finally, 'Twelve less than thrice a number' translates to 3x-12. Other choices are incorrect because they do not accurately represent the given expression. Choice B (12-3x) reverses the order of operations, choice C (3-12x) incorrectly multiplies instead of subtracting, and choice D (12x-3) mistakenly subtracts the number from 12 instead of subtracting 12 from the number multiplied by 3.

Correct Answer: A

Rationale: The correct answer is A because a prime number is defined as a number that is divisible by only 1 and itself. This means prime numbers have exactly two factors, 1 and the number itself, making them indivisible by any other number. Choice B is incorrect because prime numbers are not divisible by any other numbers except 1 and themselves. Choice C is incorrect because prime numbers are not divisible by any number, only by 1 and themselves. Choice D is incorrect because prime numbers actually have exactly two factors, not three.

Correct Answer: B

Rationale: To find 31% of 426, you multiply 426 by 0.31. So, 426 * 0.31 = 132.06. Therefore, the correct answer is B: 132.06. Option A (425.69) is close but incorrect. Options C (13.7) and D (0.07) are significantly lower than the actual result, indicating they are incorrect.

Correct Answer: D

Rationale: To find the answer, calculate the volume of the room: 9 ft * 9 ft * 9 ft = 729 cubic feet. Then, calculate the volume of one box: 2 ft * 2 ft * 2 ft = 8 cubic feet. Divide the room's volume by the box's volume: 729 cubic feet / 8 cubic feet = 91.125. Since we can't have a fraction of a box, the maximum number of whole boxes that can be stored is 91, which is closest to option D: 92. Option A (125) is too high, option B (64) is too low, and option C (18) is also too low.
