Use the ray tool to graph g(x)=
3x, x < 2
1/2x + 5, x > 2

The equation x2 – 1x – 90 = 0 has solutions {a, b}. what is a + b?

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.
