If the set X is a subset of given set Y then the complement of X is the set of elements in Y but not in X.
set A = {1, 2, 3, 4, 5}
set B = {3, 4, 5}
the complement of set B: B' = {1, 2}
Answer:
There are 2 items in the complement of b
Step-by-step explanation:
Complement of a set is all items not in the set
Complement of set b is all numbers less than and including 2
Since the sample space is 1,2,3,4,5
The only numbers in the complement of b is 1,2
2
w + 1/2 ➡ (2w + 1)/2
w/4 + 2➡ (w + 8)/4
(2w + 1)/2 = (w + 8)/4
8w + 4 = 2w + 16 ➡ 6w = 12
w = 2
You would multiply all of the numbers to get your answer so it would be 4*5*6*8 which would get you 960.
