Given that f(x) = x^2+ 2x and g(x) = x + 7, calculate (a) f o g(x)=
(b) go f(x)=
(c) fo f(x)=
(d) go g(x) =

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (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.
