Question 513679: Also, for the first SLP I want you to put into practice what you have learned about sets and functions. I want you to create three sets, set A, set B, and set C by going through the items you use at work (or in your field).
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.
Create Set C, by taking the complement of Set B in Set A, i.e. all of the non-essential items.
Are sets B and C proper subsets of set A? Explain.

Question 530531: Determine whether A = B, A ⊆ B, B ⊆ A, A ⊂ B, B ⊂ A or if none of these answers applies.
A = {x | x is all elements of N and x < 6}
B = {x | x is all elements of N and 1 is less than or equal to x is less than or equal to 5}
I believe that the answer is A=B
Would A ⊆ B and A ⊂ B also be included in my answer as well?

Question 536859: Find all sets S , if any, such that S ⊆ { 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 } and S satisfies each and all of the following conditions:
i) S ∩ { 1 , 2 , 3 , 4 , 5 } = { 2 , 4 } ,
ii) S ∪ { 2 , 3 , 5 , 6 , 8 } = { 2 , 3 , 4 , 5 , 6 , 7 , 8 } , and
iii) S – { 3 , 4 , 7 , 8 , 9 } = { 1 , 5 , 6 }
I know how to do i, ii, but iii seems to be little tricky and how to S that satisfies ALL of the following? Thanks!
