of the sequence: 4, 12, ... and the fact that 972 was some term of the sequence.

a. If the sequence is arithmetic, what is the equation of the nth term and what number term is 972?

What is the rate of change of a line that passes through (2,-5) and (6,-2)?

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.
