The number of archaeological sites discovered in a country over time, x, can be represented by the function s(x) = 2(1.1)x. the approximate number of artifacts found in each site over time, x, can be represented by the function a(x) = (1.1)5x + 2. create the function, t(x), that best describes the total number of artifacts found in archaeological sites in the country after x years.

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.
