Jamie can work no more than 20 hours a week this summer. She needs to earn at least $256 a week to save enough for a car before school starts. She makes $6 an hour babysitting and $16 an hour cleaning houses. Graph the system of inequalities that models the situation. Let x be equal to hours spent babysitting and y be equal to hours spent cleaning houses. Excluding the boundaries, place a point inside the region of the graph that satisfies the system.

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.
