The equations –a – 7b = 14 and –4a – 14b = 28 represent a system of linear equations. Which statement correctly explains how to eliminate the variable b when solving the system of equations? A. Multiply the first equation by –2 and add it to the second equation. Then solve the resulting equation, –2a = 0. B. Multiply the first equation by 2 and add it to the second equation. Then solve the resulting equation, –2a = 0. C. Divide the second equation by –4 and add it to the first equation. D. Divide the second equation by 4 and add it to the first equation.

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.)
