Multiple Choice

Equal sets have

• the exact same elements

• the same number of elements

• the opposite

• nothing

Multiple Choice

A= {letters in the word SEAT}

B= {letters in the word TASTE}

Determine if these two seats are equal or equivalent.

• Equivalent because they have the same letters

• Not equal because SEAT has 4 letters and TASTE has 5 letters

• Equal because each set has the same amount and the same letters.

Multiple Choice

Which of the following is true?

• If two sets are equivalent, then they are equal.

• The of elements in an empty set is 1.

• If two sets have exactly the same elements, then they are equal.

• if two sets are equal, then they are equivalent.

Multiple Choice

Given T= {m, 4, 7, 9} and

H= {4, 9, 3, n}

If set T and set H are equal sets,

then what is the value of m + n?

• 14

• 8

• 10

• 12

Multiple Choice

Determine the type of set.

{Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday} and {Days of the week}

• Equal

• Equivalent
