Rachel has $19.31 for a cab ride. There is an initial fee of $4.90 with a $1.25 charge for every mile traveled. This situation is modeled by the equation 1.25m + 4.90 = 19.31, where m represents the number of miles traveled. How many miles can Rachel travel? (round to the nearest tenth of miles traveled)

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.
