1. A consumer makes a $400 down payment on a television that costs $1,570. Which of the following is the number of months it will take to pay off the television with monthly payments of $100?

A. 12
B. 16
C. 15
D. 11

Correct answer: A

Rationale: After the $400 down payment, the remaining balance is $1,170. With monthly payments of $100, it will take 12 months to pay off the remaining balance. Therefore, the correct answer is 12 months. Choice B (16) is incorrect as it exceeds the required timeframe. Choice C (15) is incorrect as it is close but still one month over the correct timeframe. Choice D (11) is incorrect as it underestimates the time needed to pay off the remaining balance.

2. Histograms use ________, and bar graphs do not.

A. Ranges
B. Categories
C. Labels
D. Percentages

Correct answer: A

Rationale: Correct Answer: Ranges. Histograms utilize ranges (intervals) to display the frequency distribution of continuous data, highlighting the frequency of values falling within each interval. Bar graphs, on the other hand, represent discrete data using separate and distinct bars to show comparisons between different categories or groups. Choice B (Categories) is incorrect because both histograms and bar graphs can display data based on categories, but histograms use ranges to group continuous data. Choice C (Labels) is incorrect as both types of graphs can have labels to provide context and information. Choice D (Percentages) is incorrect because percentages can be used in both histograms and bar graphs to show proportions, but they are not a defining feature that distinguishes histograms from bar graphs.

3. What is the area of a triangle with a base of 10 cm and a height of 7 cm?

A. 70 cmÂ²
B. 35 cmÂ²
C. 140 cmÂ²
D. 100 cmÂ²

Correct answer: B

Rationale: To find the area of a triangle, you use the formula A = 1/2 Ã— base Ã— height. Substituting the given values: A = 1/2 Ã— 10 cm Ã— 7 cm = 35 cmÂ². Therefore, the correct answer is B. Choice A (70 cmÂ²) is incorrect as it seems to be the product of the base and height rather than the area formula. Choice C (140 cmÂ²) is incorrect as it appears to be twice the correct answer, possibly a result of a miscalculation. Choice D (100 cmÂ²) is incorrect as it does not reflect the correct calculation based on the given base and height values.

4. What is 4.6 rounded to the nearest integer?

A. 3
B. 4
C. 5
D. 6

Correct answer: C

Rationale: When rounding a decimal number to the nearest integer, if the decimal part is 0.5 or greater, we round up to the next integer; if it is less than 0.5, we round down. In this case, 4.6 is closer to 5 than to 4 because it is exactly halfway between the two integers. Therefore, when rounding 4.6 to the nearest integer, we round up to 5. Choice A (3), B (4), and D (6) are incorrect as they are not the nearest integer to 4.6.

5. What is the percentage equivalent of 0.0016?

A. 16%
B. 160%
C. 1.60%
D. 0.16%

Correct answer: D

Rationale: To convert a decimal to a percentage, you multiply by 100. Therefore, to find the percentage equivalent of 0.0016, you would multiply 0.0016 by 100 to get 0.16%. This means that choice D, '0.16%', is the correct answer. Choices A, B, and C are incorrect because they do not correctly represent the percentage equivalent of 0.0016.
