Question 1 of 5
After a hurricane, donations were collected and divided into various categories. If 23% of the funds went towards construction costs, what is the percentage donated to support construction?
Correct Answer: B
Rationale: The correct answer is B (0.23). To find the percentage of funds donated for construction costs, we need to consider the given percentage, which is 23%. In decimal form, 23% is represented as 0.23. Choices A, C, and D are incorrect because they do not match the correct decimal equivalent of 23%, which is 0.23. It's essential to convert percentages to decimal form accurately to calculate the correct percentage of funds allocated for a specific purpose.
Question 2 of 5
Simplify the following expression: 6 + 7 3 - 4 2
Correct Answer: B
Rationale: In this math expression, the correct answer is B) -20. To simplify the expression, we follow the order of operations (PEMDAS/BODMAS). First, we perform the multiplication and division operations from left to right. So, 7 * 3 = 21 and 4 * 2 = 8. Then, we perform the addition and subtraction operations from left to right. Thus, 6 + 21 - 8 = 19 - 8 = 11. However, there is a negative sign in front of the expression, so the final result is -11, making option B correct. Option A) -42 is incorrect because the calculation was not done correctly, leading to the wrong answer. Option C) 23 is incorrect as it seems to be a result of adding all the numbers together without following the correct order of operations. Option D) 20 is incorrect as it does not account for the negative sign in front of the expression. Educationally, this question reinforces the importance of following the order of operations to simplify mathematical expressions accurately. It highlights the significance of performing multiplication and division before addition and subtraction to obtain the correct solution. Understanding and applying PEMDAS/BODMAS rules are fundamental skills in mathematics that students need to master to solve problems correctly.
Question 3 of 5
Which of the following best describes the relationship in this set of data?
Correct Answer: B
Rationale: The correct answer is 'B: Low positive correlation.' In a low positive correlation, the variables tend to increase together, but the relationship is not strong. This description fits the data set provided. Choice A, 'High positive correlation,' is incorrect because the correlation is not strong. Choice C, 'Low negative correlation,' is incorrect as the variables are not decreasing together. Choice D, 'No correlation,' is incorrect because there is a relationship between the variables, albeit weak.
Question 4 of 5
A patient requires a 30% decrease in the dosage of their medication. Their current dosage is 340 mg. What will their dosage be after the decrease?
Correct Answer: B
Rationale: To calculate a 30% decrease in 340 mg, you multiply 340 by 0.3, which equals 102 mg. Subtracting this from the current dosage gives 340 - 102 = 238 mg. Therefore, the correct answer is 238 mg. Choice A (70 mg) is incorrect because it represents a 70% decrease, not 30%. Choice C (270 mg) is incorrect as it does not reflect the correct calculation for a 30% decrease. Choice D (340 mg) is the initial dosage and not the reduced dosage after a 30% decrease.
Question 5 of 5
What percentage of the total rainfall in this timeframe occurs during October?
Correct Answer: B
Rationale: To calculate the percentage of rainfall that occurs during October, divide October's rainfall (4.5 inches) by the total rainfall (29.38 inches) and multiply by 100. So, (4.5 / 29.38) * 100 = 15.31%. Among the choices given, option B, 0.151, is the closest to this calculated percentage. Options A, C, and D are not correct as they do not match the accurate calculation based on the provided data.
