 Express each set in Roster Form

 The set of Months that do not end in “r”
 E = {x  x ∈ N and 22 < x ≤ 38 }

 Express each set in SetBuilder Notation
 C = {21, 28, 35, 42, 49, 56}
 A is the set of months that have >30 days.
 Refer to Figure T14 on the “Test No 1 Information and FactConcept Sheet”. Use the graph to represent the set of years in which the cost of a Super Bowl commercial was less than or equal to $2.75 M.
 Answer true or false. If false give the reason.
 {baseball, football, soccer} ⊂ {football, baseball, soccer}

 If X⊆Z and Z⊆X, what other relationships exist between X and Z?
 Doogie is ordering a pizza at a restaurant. He can purchase a pizza consisting of just crust/sauce/cheese or he can add any of the following items: peppers, olives, onions, mushrooms, sausage, meatballs. How many different variations of a pizza are possible.
 For the sets U, A and B, construct a Venn diagram and place the elements in the proper regions.
U = {1^{st} Base, 2^{nd} Base, 3^{rd} Base, Shortstop, catcher, pitcher, left field,
right field, center field}
A = {right field, center field, left field}
B = {1^{st} Base, 2^{nd} Base, 3^{rd} Base}
 Refer to Figure T110 on the “Test No 1 Information and FactConcept Sheet”. That table shows the annual sales revenue and net income, in millions of dollars, for a major us manufacturing company for the years 20092013. Let those years represent the Universal Set.
Let A = the set of years in which sales revenue was at least $1.5 Billion
Let B = the set of years in which net income was greater than $500 Million.
Construct a Venn diagram illustrating the sets.
 The results of a survey of customers at a hair salon showed that 26 got their hair cut, 38 got a manicure and 14 got a manicure and their hair cut. How many got either a manicure or their hair cut?
 Refer to Figure T113 on the “Test No 1 Information and FactConcept Sheet”.
Use the Venn Diagram on the figure to list the sets in roster form
 A ∩ (C ∪ B )
 C’
13. Refer to Figure T114 on the “Test No 1 Information and FactConcept Sheet”.
Write a description of the shaded area. Use union, intersection and compliment as necessary.
14. Use a Venn Diagram or DeMorgan’s Laws to determine whether the following
statements are equal — B’ ∪A’ and (A ∪ B)’
