Answer:
a) A n (B' n C') = {3, 9}.
b) (AUB) n (BUC) = {2,4,5,6,7,8}
Step-by-step explanation:
a) Rewriting C ; C = {4,5,6,7,8}
B' = {3,5,7,9} and C' = {2, 3, 9}
so (B' n C') = {3, 9}
and A n (B' n C') = {3, 9}.
b) {A U B} = { 2,3,4,5,6,7,8,9} and {B U C} = {2,4,5,6,7,8}
so (AUB) n (BUC) = {2,4,5,6,7,8}
the answer to this expression is -175
B.It takes more than 12 loads to wash 9 bins of towels.
The function f(x) gives the number of loads required when there are x bins of towels to be washed.
f(x)=Number of loads
x=Bins of towels
Therefore in the inequality f(9)>12
If f(9)>12, it means Number of loads is more than 12.
f(9)>12 therefore tells us that it takes more than 12 loads to wash 9 bins of towels.
The correct option is B
