Suppose we define the relation R on the set of all people by the rule "a R b if and only if a is Facebook friends with b."

Is this relation reflexive? Is is symmetric? Is it transitive? Is it an equivalence relation?

Briefly but clearly justify your answers.

Expert Solution

A relation R is called an equivalence relation if it is reflexive,asymmetric and transitive.

Suppose we define a relation ~ on the set of nonzero real numbers R* = R\{0} by for all a , b E R*, a ~ b if and only if ab>0. Prove that ~ is an equivalence relation. Find the equivalence class [8]. How many distinct equivalence classes are there?

Determine whether the relation R on the set of all people is reflexive, symmetric, antisymmetric, and/or transitive, where (a, b) ∈ R if and only if a) a is taller than b. b) a and b were born on the same day.

On the set S of all real numbers, define a relation R = {(a, b):a ≤ b}. Show that R is transitive.

Suppose we define a relation on the set of natural numbers as follows. Two numbers are related iff they leave the same remainder when divided by 5. Is it an equivalence relation? If yes, prove it and write the equivalence classes. If no, give formal justification.

1)Let S be the set of all students at a college. Define a relation on the set S by the rule that two people are related if they live less than 2 miles apart. Is this relation an equivalence relation on S? Justify your answer. 2) Define another relation on the set S from problem 5 by defining two people as related if they have the same classification (freshman, sophomore, junior, senior or graduate student). Is this an equivalence relation...

Question 1. Equivalence Relation 1 Define a relation R on by iff . Prove that R is an equivalence relation, that is, prove that it is reflexive, symmetric, and transitive. Determine the equivalence classes of this relation. What members are in the class [2]? How many members do the equivalence classes have? Do they all have the same number of members? How many equivalence classes are there? Question 2. Equivalence Relation 2 Consider the relation from last week defined as:...

Determine whether the relation R on the set of all real numbers is reflexive, symmetric, antisymmetric, and/or transitive, where (x,y) ∈ R if and only if: a) x = 1 OR y = 1 b) x = 1 I was curious about how those two compare. I have the solutions for part a) already.
