Can someone explain how to solve this problem? I am very confused on what to do. A = {3, 4, 7}

B = {1, 2, 5, 8}

U = {0,1,2,3...10}

Find the set:
(A n B) U (A n B')
within the universal set

(A intersect B) union (A intersect compliment B)

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

Which graph represents the linear function below? y-3=1/2(x+2)

Which situation is an example of an observational study?
