A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 47 ft/s. Its height in feet after t seconds is given by y = 477 - 12t2.
a.) Find the average velocity for the time period beginning when to= 2 second and lasting for the given time.
t=.01 sec:
t=.005 sec:
t = .002 sec :
t = .001 sec:
b.) Estimate the instanteneous velocity when t = 2.

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.)
