2. The graph shows the vertical displacement y, in centimeters, that a weight bouncing from a spring would achieve if there were no friction, for a given number of seconds, x.

a. What is the weight’s maximum displacement?

b. From its resting position, how long does it take the weight to bounce one direction, then the other, and then return to its resting position?

c. What is the graph’s frequency and what does it indicate in this situation?

d. How is the weight moving during the time period x=6 to x=7.5?

pls help, thank you! <3

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.)
