1. B and C has well defined elements while A has broad scope
2. C = { }
3. The set of multiples of 4 less than 40.
4. A = {x|x is a set of the types of angles}
5. Possible subsets are 4,8,12
6. 9
7. {0}
8. {1,3,5,7,9}
9. A-B = {2,4,6,8,10,12,14,16,18}
10. U={1,2,3,4,5,6,7,8,9}
Step-by-step explanation:
1. B and C has well defined elements while A has broad scope
2. C is a null set since multiples of 5 starts from 5,10,15,... so forth
3. The set of multiples of 4 less than 40. Look closely at the common ratio.
4. A = {x|x is a set of the types of angles}
5. Possible subsets are 4,8,12
6. Count all elements
7. Find the common element among all sets. Hence, {0}
8. Combine the elements of A and B then cross out all elements in the union AuB that are present in C. The remaining elements in AuB will be the difference.
9. positive number less than 20 are A={2,4,6,8,10,12,14,16,18}. The odd numbers are B = {1,3,5,7,9,11,13,15,17,19,...}
Cross out all elements in A that are present in B. The remaining elements in A is the difference.
A-B = {2,4,6,8,10,12,14,16,18}
10. Combine all elements so U={1,2,3,4,5,6,7,8,9}
