An airplane is flying on a bearing of 80o (recall bearing means an angle clockwise from polar north of a given number of degrees) at a speed of 540 mph. The airplane encounters a wind of 55 mph with a bearing of 100o. a. Find the velocity with respect to ground of the airplane. Then find the bearing.

In the following situation, determine whether you are asked to determine the number of permutations or combinations. then do the calculation how many ways are there to pick a starting five from a basketball team of twelve members? a. permutation; ps - 2520 b. combination; 1c, - 792 c. combination: 2cs - 2520 d. permutation; ps - 95040

If c(x) = 4x – 2 and d(x) = x2 + 5x, what is (cxd)(x)

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.
