Question

1. Choose the correct solution in roster form.

N is the set of real numbers that are factors of 12

2. Write the solution to the inequality in set-builder notation.

5r + 8 < 63

3. Suppose U = {1, 2, 3, 4, 5, 6, 7, 8} is the universal set and P = {2, 4, 6, 8}. What is P'?

For questions 4 and 5, suppose U={0, 1, 2, 3, 4, 5, 6}, A={2, 4, 6}, and B={1, 2, 3}. Tell whether each statement is true or false.
4. A (big c with line under it) U (1 point)

5. B (big c with line under it) A

Answer 1

1= {1,2,3,4,6,12}

2= 5r + 8 < 63
5r -8
5r < 55= r < 11

{0,1,2,3,4,5,6,7,8,9,10}

3= P' {1,3,5,7}

Im stuck on 4,5..actually i came to this site to look for some help on it
