Answer's to the Unit 1 Practice Quiz:

2a) This number is irrational because it is a non-repeating, non-terminating decimal and therefore can not be written as a fraction.

2b) This number is an irrational number because 150 is not a perfect square, therefore when it is simplified it is a non-repeating, non-terminating decimal.

2c) This number is rational since it can be written as a fraction.  Rational numbers are either terminating or repeating decimals. (Can be written as 7/9)

2d) This number is rational since it can be written in "a" divided by "b" form.  -33/7

3)  Given Expression
      Distributive Property
     Commutative Property of Addition
     Associative Property of Addition
     Additive Inverse
     Additive Identity

4a) -4.6

4b) pi

4c) impossible

4d) -7

5a) The set of natural numbers is closed under addition because whenever you add two natural numbers together the sum will always be another natural number.  (EX: 6 + 56 = 62)

5b) The set of natural numbers is NOT closed under addition because when you divide 6 by 12 (both of which are natural numbers) the quotient is 0.5 which is not a natural number.

6b) E' =  { 1, 3, 5, 7, 9}
      E u P = {2, 3, 4, 5, 6, 7, 8, 10}
      F n P = { 2, 3, 5}
      (E u P) n F = {2, 3, 5, 8}
     (E u F)' = {7, 9}

Good Luck Studying!  Feel free to post questions if you have them!
