Whdss the solutions to the graphs?

Give the equations of two different lines that are perpendicular to the line 3x + 4y = 7.

If a || b and b | y, then ? a) x || y. b) x | a. c) a | y. d) a || y.

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.
