Part A: 
Tara is incorrect because she has softball practice 4 days in a week and each practice is at least 1 hour. Therefore, she practices at least 4 hours a week.

Part B:
4 days with 1 1/3 hour per day, a total of 5 1/3 hours a week.

1 1/3 convert to fraction : (3*1 + 1)/3 = 4/3
4 * 4/3 = 16/3 
16/3 = 5 1/3

Consider the universal set U and the sets X, Y, Z. U={1,2,3,4,5,6} X={1,4,5} Y={1,2} Z={2,3,5} What is (Z⋃X′)⋂Y?
beks73 [17]

X' = U - X

= {1,2,3,4,5,6} - {1,4,5}

= {2,3,6}

(ZUX') = {2,3,5} U {2,3,6}

= {2,3,5,6}

(Z⋃X′)⋂Y = {2,3,5,6} ⋂ {1,2}

= {2}
