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}
y = x + 7
x = number of weeks
y = the total number of quizzes y.
<em>Cole has already taken 7 quizzes = </em>+ 7
<em>he expects to have 1 quiz during each week of this quarter = </em>1x
y = 1x + 7
