Question 1 of 5

At a car dealership, employees earn a monthly base salary of $2,000 plus 3% commission on total sales. If an employee makes $5,000 in sales, what will their total monthly earnings be?

Correct Answer: A

Rationale: The correct answer is A: $2,500. To calculate the total monthly earnings, first determine the commission earned on sales: $5,000 * 3% = $150. Add this to the base salary of $2,000: $2,000 + $150 = $2,150. Therefore, the total monthly earnings will be $2,150.

Question 2 of 5

What is the probability of flipping a coin and getting heads?

Correct Answer: A

Rationale: The correct answer is A: 1/2. When flipping a fair coin, there are only two possible outcomes - heads or tails. Since each outcome is equally likely, the probability of getting heads is 1 out of 2, or 1/2. Choice B (1/3), C (1/4), and D (1/5) are incorrect because they do not accurately reflect the equally likely outcomes of a coin flip. The probability of getting heads is always 1/2 when flipping a fair coin.

Question 3 of 5

Simplify the following expression: 3 (1/6) - 1 (5/6)

Correct Answer: B

Rationale: To simplify the expression 3(1/6) - 1(5/6), we first multiply the whole number by the fraction: 3 * 1/6 = 3/6. Then, we subtract 1 * 5/6 = 5/6. Simplifying 3/6 - 5/6 gives us -2/6, which reduces to -1/3 or 1 (1/3). Therefore, the correct answer is B: 1 (1/3). Choice A: 2 (1/3) is incorrect as the result is negative. Choice C: 2 (1/9) is incorrect as it is not the simplified form. Choice D: 5/6 is incorrect as it is one of the terms in the expression, not the final result.

Question 4 of 5

Given the double bar graph shown below, which of the following statements is true?

Correct Answer: B

Rationale: The correct answer is B: Group A is positively skewed, while Group B is approximately normal. This is because in a positively skewed distribution, the tail of the graph extends to the right, indicating a higher frequency of lower values. In the double bar graph provided, Group A has a longer bar on the left side, suggesting a higher concentration of lower values, which is indicative of positive skewness. Group B, on the other hand, shows a more symmetrical distribution, with bars of similar length on both sides, implying an approximately normal distribution. Other choices are incorrect because: A: Group A is not negatively skewed, as it has a longer left tail. C: Group A is not approximately normal, as it shows characteristics of positive skewness. D: Group B is not positively skewed, as it does not have a longer right tail.

Question 5 of 5

Which of the following describes a graph that represents a proportional relationship?

Correct Answer: C

Rationale: The correct answer is C because a graph representing a proportional relationship has a constant slope that is equal to the rate of change between the variables. In this case, a slope of 2,000 means that for every unit increase in x, there is a corresponding increase of 2,000 in y, indicating a proportional relationship. The y-intercept being 0 is also consistent with a proportional relationship as it implies that when x is 0, y is also 0. A, B, and D are incorrect because their slopes and y-intercepts do not represent a proportional relationship. A slope of 2,500, 1,500, and -1,800 in choices A, B, and D respectively, do not indicate a constant rate of change between x and y, which is crucial for a proportional relationship. The y-intercepts in these choices also do not align with the characteristics of a proportional relationship.
