Vocabulary: Categorize the subsets into the set(s) to which they belong. Some subsets may belong to multiple sets or not set at all.

Note that not all subsets for every set are included in this item.

  • {}
  • {3}
  • {1, 3}
  • {1, 3, 5}
  • {1, 3, 5, 7}
  • Set {1, 3, 5}
  • Set {1, 3}
  • Set {3}
Question 15

Reasoning: A nonempty set is a set that contains at least one element. Given nonempty sets A and B, suppose that A ⊆ B. Is B ⊆ A always, sometimes, or never true?

Question 17

Error Analysis: A student says sets A and B below are the same. What error did the student make?

A = {x| x is a whole number less than 5} B = {1, 2, 3, 4}

Review Lesson 3-1: Graph the pair of inequalities on the same number line.

Question 25
25.

Vocabulary Review: Identify the numbers in the left column that are NOT whole numbers.

  • NOT whole numbers
Question 26

Use Your Vocabulary: Complete each set on the right with the most appropriate element from the left.

  • sister
  • cat
  • mouth
  • I
  • {eyes, ears, nose, _?_}
  • {mother, father, brother, _?_}
  • {A, E, _?_, O, U}
Question 27
27.

Use Your Vocabulary: Suppose that the universal set of coins is {penny, nickel, dime, quarter}. Let D be the set {penny, quarter}. What is the complement of set D ?

Drag and drop elements from the left to create the complement of set D on the right.

  • penny
  • nickel
  • dime
  • quarter
  • Complement of D
