As we know, a set is just a collection of objects that are similar in some way, like a gaggle of geese, pride of lions, or an army of ants. To further classify our world, we can create subsets from a larger set. Let's consider the idea of a subset for our discussion. Give an example of a subset and a proper subset. Explai

1. As a business owner, there are many decisions that you need to make on a daily basis, such as ensuring you reach the highest production levels possible with your company's products. Your company produces two models of bicycles: Model A and Model B. * Model A takes 2 hours to assemble. * Model B takes 3 hours to assemble.

Set A will be a list of five items you personally NEED to buy the most (essential items). Set B will be a list of five items that you WANT to buy the most (fun stuff). List the items in Set A and Set B, and also list or state the items in the union and in the intersection of Set A and Set B. Now assume that the prices of th

What is the identity element of M(3,2,W) under addition? M(m,n,S) is the notation for the set of matrices with m rows and n columns, such that each element is a member of the set S. So M(3,2,W) is the set of 3 x 2 matrices with whole numbers for each element. Thanks.

1. Without writing them all out, what is the number of subsets of set A ={king, queen, knight, prince, princess, duke}? 2. Given these elements of sets A, B, and C list the elements of set D. Show your work step by step. A = {1, 2, 3, 4} B = {3, 4, 5, 6, 7} C = {3, 5, 7, 9} D = A intersected with (B U C)

For the first SLP I want you to put into practice what you have learned about sets and counting. I want you to create three sets, set A, set B, and set C by going through the items in your wallet or purse. Set A will be a list of all of these items. Create Set B, from the items in Set A that you think are essential.

Prove that there exists a subjection from P(N) onto omega_1, where N is the set of all natural numbers, P(N) is the power set of N, and omega_1 is the least uncountable ordinal. See attachments for fully formulated problem.

What are some similarities and differences between permutations and combinations? Give a real-life example of either a permutation or combination.

The input consists of two arrays each representing a set of integers (in each array, each value appears only once). The output is an array representing the union of the two sets - again, each value appears only once. Write a method to implement set union and analyze its running time.
