The product of two consecutive integers is 72. The equation x(x + 1) = 72 represents the situation, where
represents the smaller integer. Which equation can be factored and solved for the smaller integer?
1 x2 + x-72=0
x2+x+72 = 0
2 + 2x - 72 = 0
2 + 2x + 72=0

Intro

An oil exploration company currently has two active projects, one in asia and the other in europe. let a be the event that the asian project is successful and b be the event that the european project is successful. suppose that a and b are independent events with p(a) = 0.2 and p(b) = 0.8. (a) if the asian project is not successful, what is the probability that the european project is also not successful? (b) what is the probability that at least one of the two projects will be successful? (c) given that at least one of the two projects is successful, what is the probability that only the asian project is successful? (round your answer to three decimal places.)
