Math Practice TEAS Test

Correct Answer: B

Rationale: The correct answer is B: Low positive correlation. This is because the data shows a general increasing trend, but the points are scattered and do not form a tight linear relationship. The correlation coefficient would be closer to 0 than to +1, indicating a weak positive correlation. Choices A and C are incorrect as they suggest stronger correlations, which is not supported by the data. Choice D is incorrect as there is some level of relationship between the variables, even if it is weak.

Correct Answer: B

Rationale: To find the total cost, we add up the prices of the dress, shoes, and accessories: $69.99 (dress) + $39.99 (shoes) + $34.67 (accessories) = $144.65 Therefore, the correct answer is B. Option A is incorrect as it misses the cost of the shoes. Option C has an incorrect calculation. Option D is almost correct but has a typographical error.

Correct Answer: B

Rationale: To determine how many questions Joshua must answer correctly, we set up the inequality: 4x > 92, where x represents the number of questions answered correctly. With 30 questions, Joshua needs more than 92 points, meaning he must score more than (30 questions * 4 points per question = 120 points). Therefore, answer B (4x > 92) is correct. Choices A, C, and D are incorrect because they do not accurately reflect the requirement of scoring more than 92 points to qualify for the scholarship.

Correct Answer: B

Rationale: To calculate a 30% decrease, you multiply the current dosage (340 mg) by 0.30 to find the decrease amount: 340 mg x 0.30 = 102 mg. Subtract the decrease from the current dosage to get the new dosage: 340 mg - 102 mg = 238 mg (Option B). Option A (70 mg) is incorrect as it represents a 79% decrease. Option C (270 mg) is incorrect as it does not account for the 30% decrease. Option D (340 mg) is incorrect as it does not reflect the required decrease.

Correct Answer: B

Rationale: The correct answer is B: Frequency. A histogram is preferred over a bar graph when displaying frequency distribution data, as it shows the frequency of values within intervals or bins. It is used to represent continuous data and helps visualize the distribution and shape of the data. Choice A is incorrect because bar graphs are typically used for comparing different categories. Choices C and D are incorrect because percentages and proportions are more suitable for other types of graphs like pie charts or stacked bar graphs.
