The formula d = 1.2ť? + t + 1 expresses a car's distance (in feet to the north of an intersection, d, in terms of the number of seconds t since the car started to move
a. As the time t since the car started to move increases from t = 2 tot = 5 seconds, what constant speed must a truck travel to cover the
same distance as the car over this 3-second interval?

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.
