Please Help!!!! thanks :)
1. Suppose U= {1,2,3,4,5,6,7,8,9,10} is the universal set, and P= {2,4,6,8,10}. What is P'?
a: {1,2,3,4,5,6,7,8,9,10}
b: {3,5,7,9}
c: {1,3,5,7,9}***
d: {2,4,8}
2. If D is the set of natural numbers that are whole numbers less than 3, choose the selection below that correctly shows this set in roaster and setbuilder notation.
a: D= { 0,1,2,3,4,5} ; D= {x is a whole number, x<3}
b: D= {0,1} ; D= {x  x <3}
c: D= {0,1,2} ; D= {x  x os a whole number, x < 3}
d: D= {0,1,2,3,4,5,6,7} ; D {x < 3}**
3. Which compound inequality and graph represent the following phrase?
All real numbers that are less than 5 or greater than 10
a: y<5 or y > 10
b: y<5 or y < 10
c: y>5 or y < 10**
d: y>5 or y > 10
The stars next to the answer is what i have picked.
