What is the least common denominator of two fractions?

  • A. The smallest number that is a multiple of both denominators
  • B. The smallest number that both fractions can divide into evenly
  • C. The least common multiple of both denominators
  • D. The greatest common factor of both denominators
Correct Answer: C

Rationale: The least common denominator of two fractions is the least common multiple of both denominators. This is because the least common denominator is the smallest number that both denominators can divide into evenly, ensuring that both fractions can be expressed with a common denominator. Choice A is incorrect as the least common denominator is a multiple of both denominators, not a number that multiplies into both. Choice B is incorrect because the common denominator needs to be a multiple of both denominators, not just a number they can divide into evenly. Choice D is incorrect as the greatest common factor is not used to find the least common denominator, but rather the least common multiple.

How many quarts are in a gallon?

  • A. 1 quart
  • B. 2 quarts
  • C. 3 quarts
  • D. 4 quarts
Correct Answer: D

Rationale: The correct answer is D, which is 4 quarts in a gallon. In the US customary system, there are 4 quarts in a gallon. Choice A is incorrect as it represents the equivalent of a quart, not a gallon. Choice B and C are incorrect as they are smaller quantities than a gallon and do not match the conversion of quarts to a gallon.

Given a double bar graph, which statement is true about the distributions of Group A and Group B?

  • A. Group A is negatively skewed, Group B is normal.
  • B. Group A is positively skewed, Group B is normal.
  • C. Group A is positively skewed, Group B is neutral.
  • D. Group A is normal, Group B is negatively skewed.
Correct Answer: B

Rationale: The correct answer is B. In statistical terms, a positively skewed distribution means that the tail on the right side of the distribution is longer or fatter than the left side, indicating more high values. Therefore, Group A is positively skewed. Conversely, an approximately normal distribution, also known as a bell curve, is symmetrical with no skewness. Hence, Group B is normal. Choices A, C, and D are incorrect because they do not accurately describe the skewness of Group A and the normal distribution of Group B as depicted in a double bar graph.

Simplify the following expression:
6 + 7 3 - 4 2

  • A. -42
  • B. -20
  • C. 23
  • D. 20
Correct Answer: B

Rationale: ollow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)):

Multiply: 7 3 = 21, and 4 2 = 8
Perform addition and subtraction: 6 + 21 - 8 = 19
Thus, the simplified expression equals 19.

How can you visually differentiate between a histogram and a bar graph?

  • A. A bar graph has gaps between the bars; a histogram does not
  • B. A bar graph displays frequency; a histogram does not
  • C. A histogram illustrates comparison; a bar graph does not
  • D. A bar graph includes labels; a histogram does not
Correct Answer: A

Rationale: The key difference between a histogram and a bar graph is that a bar graph has gaps between the bars, while a histogram does not. This feature helps in visually distinguishing between the two. Choice B is incorrect because both types of graphs can show frequency. Choice C is incorrect as both graphs can be used for comparison. Choice D is incorrect as both types of graphs can have labels for better understanding.

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

  • A. 123 pounds
  • B. 110 pounds
  • C. 156 pounds
  • D. 137 pounds
Correct Answer: A

Rationale: To convert kilograms to pounds, you multiply the weight in kilograms by 2.2. So, 56 kilograms * 2.2 = 123.2 pounds, which can be approximated to 123 pounds. Therefore, Choice A is correct. Choices B, C, and D are incorrect as they do not match the correct conversion from kilograms to pounds for Stella's weight of 56 kilograms.
