Example Question #7 :Theory Of Positive Integers

Which of the following is a property of a relation?

Possible Answers:

Non-symmetric Property

分区的ty

Symmetric Property

Equivalency Property

All are properties of a relation

Correct answer:

Symmetric Property

Explanation:

For a relation to exist there must be a non empty set present. If a non empty set is present then there are three relation properties.

These properties are:

I. Reflexive Property

II. Symmetric Property

III. Transitive Property

When all three properties represent a specific set, then that set is known to have an equivalence relation.

Example Question #8 :Theory Of Positive Integers

What is an equivalency class?

Possible Answers:

Correct answer:

Explanation:

An equivalency class is a definitional term.

Supposeis a non empty set andis an equivalency relation on. Thenbelonging tois a set that holds all the elements that live inthat are equivalent to.

In mathematical terms this looks as follows,

Example Question #9 :Theory Of Positive Integers

Which of the following is a property of a relation?

Possible Answers:

Equivalency Property

Non-symmetric Property

All are relation properties

Associative Property

Reflexive Property

Correct answer:

Reflexive Property

Explanation:

For a relation to exist there must be a non empty set present. If a non empty set is present then there are three relation properties.

These properties are:

I. Reflexive Property

II. Symmetric Property

III. Transitive Property

When all three properties represent a specific set, then that set is known to have an equivalence relation.
