Explanation Given: { 1 , 2 , 3 , 4 } Formula Used: The given set forms group if the below four conditions are satisfied The set should be closed with respect to the operation The associative property of the operation should hold true for the elements of set The identity element should exists in the operation for all the elements of set For each element in the set has an inverse. Calculation: The set is given as { 1 , 2 , 3 , 4 } Condition 1: We have ( 1 × 1 ) mod 5 = 0 mod 5 = 0 , which belongs to { 1 , 2 , 3 , 4 } ( 1 × 2 ) mod 5 = 2 mod 5 = 2 , which belongs to { 1 , 2 , 3 , 4 } Thus, set { 1 , 2 , 3 , 4 } is closed with respect to multiplication modulo 5 Condition 2: [ [ ( 1 × 2 ) mod 5 ] × 3 ] mod 5 = [ [ 2 mod 5 ] × 3 ] mod 4 = [ 2 × 3 ] mod 5 = 6 mod 5 = 1 [ [ 1 × ( 2 × 3 ) mod 5 ] ] mod 5 = [ 1 × [ 6 mod 5 ] ] mod 5 = [ 1 × 1 ] mod 5 = 1 mod 5 = 1 Here, the associative property of multiplication modulo 5 holds true for the set { 1 , 2 , 3</

Set Theory

Every field in the present world involves a set. The theory of sets was developed by German mathematician Georg Cantor while working on the “problems of trigonometric series”.

Review a classmate's Main Post. 1. State if you agree or disagree with the choices made for additional analysis that can be done beyond the frequency table. 2. Choose a measure of central tendency (mean, median, mode) that you would like to compute with the data beyond the frequency table. Complete either a or b below. a. Explain how that analysis can help you understand the data better. b. If you are currently unable to do that analysis, what do you think you could do to make it possible? If you do not think you can do anything, explain why it is not possible.
