Alex goes on a river boat tour while on vacation. The maximum speed of the boat in still water is 13 miles per
hour. The boat travels 24 miles downstream in the same amount of time it takes the boat to travel 15 miles
against the current. What is the equation to solve for the rate of the current?

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.
