You measure the width of your door to be 36 inches. The true width of the door is 75 inches. What is the relative error in your measurement?

  • A. 0.52%
  • B. 0.01%
  • C. 0.99%
  • D. 0.10%
Correct Answer: A

Rationale: The relative error is calculated using the formula: (|Measured Value - True Value| / True Value) * 100%. Substituting the values given, we have (|36 - 75| / 75) * 100% = (39 / 75) * 100% ≈ 0.52 * 100% = 0.52%. Therefore, the relative error in measurement is approximately 0.52%. Choice A is correct because it reflects this calculation. Choice B is incorrect as it represents a lower relative error than the actual value obtained. Choice C is incorrect as it overestimates the relative error. Choice D is incorrect as it underestimates the relative error.

Juan wishes to compare the percentages of time he spends on different tasks during the workday. Which of the following representations is the most appropriate choice for displaying the data?

  • A. Line plot
  • B. Bar graph
  • C. Line graph
  • D. Pie chart
Correct Answer: D

Rationale: A pie chart is the most appropriate choice for displaying the percentages of time spent on different tasks during the workday because it visually represents parts of a whole. In this case, each task's percentage represents a part of the entire workday, making a pie chart an ideal way to compare these percentages. Line plots, bar graphs, and line graphs are not suitable for showing percentages of a whole; they are more commonly used for tracking trends, comparing values, or showing relationships between variables but do not efficiently represent parts of a whole like a pie chart does.

When rounding 2678 to the nearest thousandth, which place value would be used to decide whether to round up or round down?

  • A. Ten-thousandth
  • B. Thousandth
  • C. Hundredth
  • D. Thousand
Correct Answer: B

Rationale: When rounding 2678 to the nearest thousandth, you would look at the digit in the thousandth place, which is 7. To decide whether to round up or down, you consider the digit to the immediate right of the place you are rounding to. Since 7 is equal to or greater than 5, you round up. Choice A, ten-thousandth, is incorrect as we are rounding to the thousandth place. Choice C, hundredth, is not relevant as we are not rounding to that place value. Choice D, thousand, is incorrect as it is the original number being rounded, not the place value used for rounding.

Calculate the sum of the numbers from 1 to 6:

  • A. 30
  • B. 21
  • C. 15
  • D. 13
Correct Answer: B

Rationale: To find the sum of numbers from 1 to 6, we add them together: 1 + 2 + 3 + 4 + 5 + 6 = 21. Therefore, the correct answer is 21. Choice A (30) is incorrect because it is not the sum of the numbers 1 to 6. Choice C (15) is incorrect as it is the sum of numbers 1 to 5. Choice D (13) is incorrect as it is the sum of numbers 1 to 4, not 1 to 6.

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.

The value of 6 x 12 is the same as:

  • A. 2 x 4 x 4 x 2
  • B. 7 x 4 x 3
  • C. 6 x 6 x 3
  • D. 3 x 3 x 4 x 2
Correct Answer: A

Rationale: To find the value of 6 x 12, we multiply 6 by 12, which equals 72.
A: 2 x 4 x 4 x 2 = 32
B: 7 x 4 x 3 = 84
C: 6 x 6 x 3 = 108
D: 3 x 3 x 4 x 2 = 72
Therefore, the correct answer is A, as the product of 2 x 4 x 4 x 2 equals 32, which is the same as 6 x 12.
