Question 1 of 5

In Mrs. McConnell's classroom, there are 5 students with hazel eyes and 2 students with green eyes out of a total of 30 students. What percentage of the students have either hazel or green eyes?

Correct Answer: A

Rationale: To find the percentage of students with hazel or green eyes, add the number of students with hazel and green eyes (5+2=7). Then, divide this sum by the total number of students (7/30). Finally, multiply the result by 100 to convert it to a percentage (7/30 * 100 = 23%). Therefore, the correct answer is A (0.23). Choice B (0.3) is incorrect as it is not the accurate percentage of students with hazel or green eyes. Choice C (0.47) and choice D (0.77) are also incorrect as they do not represent the correct calculation of the percentage based on the given information.

Question 2 of 5

What is the probability of consecutively pulling two more orange blocks, without replacement, from a bag containing 3 orange blocks, 5 green blocks, and 4 purple blocks?

Correct Answer: B

Rationale: To calculate the probability of consecutively pulling two more orange blocks, we first find the probability of pulling one orange block (3/12) and then the probability of pulling another orange block out of the remaining orange blocks (2/11). Multiplying these probabilities gives (3/12) * (2/11) = 6/132 = 3/55. Therefore, the correct answer is B. Choice A (3/12) is the probability of pulling one orange block, but it doesn't account for the second draw. Choice C (2/10) is incorrect as it doesn't consider the changing probabilities after the first draw. Choice D (1/3) is the probability of pulling one orange block only.

Question 3 of 5

Histograms use ________, and bar graphs do not.

Correct Answer: A

Rationale: The correct answer is A: Ranges. Histograms display continuous data in intervals or ranges, showing the frequency of data points within each range. This is a key feature that distinguishes histograms from bar graphs, which depict discrete categories. Ranges are crucial in histograms to visualize the distribution of data across different intervals, allowing for a better understanding of the data's spread and frequency distribution. Choices B, C, and D are incorrect as bar graphs also utilize categories, labels, and percentages in their presentation of data, respectively.

Question 4 of 5

Joshua needs more than 92 points to qualify for a scholarship. Each question is worth 4 points, and there are 30 questions. What inequality determines how many questions he must answer correctly?

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.

Question 5 of 5

If Stella's current weight is 56 kilograms, what is her approximate weight in pounds?

Correct Answer: A

Rationale: To convert kilograms to pounds, we use the conversion factor 1 kg = 2.20462 lbs. So, to find Stella's weight in pounds, we multiply her weight in kilograms (56) by the conversion factor: 56 kg * 2.20462 lbs/kg ≈ 123.46 lbs. Therefore, Stella's approximate weight in pounds is 123 pounds. Choice B (110 pounds) is incorrect as it underestimates the conversion. Choice C (156 pounds) and D (137 pounds) overestimate the conversion.
