Question

1. Choose the correct solution in roster form.
N is the set of natural numbers that are factors of 12.
{1, 2, 3, 4, 6}
{1, 2, 3, 4, 6, 12}
{1, 2, 3, 4, 5, 6, 8, 12} *this is my answer
{1, 2, 3, 4, 5, 6, 7, 8, 10, 11, 12}
2. Write the solution to the inequality in set-builder notation.
5r + 8 < 63
{r|r<11}
{r|r<15}
{r|r<71}
{r|r<8}
3. Suppose U = {1, 2, 3, 4, 5, 6, 7, 8} is the universal set and P={2, 4, 6, 8}. What is P?
{2, 4, 6, 8}
{1, 2, 3, 4, 5, 6, 7, 8}
{1, 3, 5, 7}
{1, 3, 5, 7, 8}
For problems 4-5, use the following information.
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 U
true
false
5. B A
true
false
Thank you so much in advance!!!

Answer 1

1. 8 is a factor of 12??
12/8 = 3/2 = 1.5

2 55/5 = 11

3. You said what P was

4 and 5 are incomplete problem statements
both A and B are subsets of U
2 is the intersection of A and B

Answer 2

Hmmmmmm mmmm
