Suppose you are determining the growth rate of two species of plants. species a is 12 cm tall and grows 2 cm per month. species b is 10 cm tall and grows 3 cm per month. which system of equations models the height of each species h(m) as a function of months m.

h(m ) = 12 + 2m
h(m ) = 3 + 10m
h(m ) = 2 + 12m
h(m ) = 3 + 10m
h(m ) = 12 + 2m
h(m ) = 10 + 3m
h(m ) = 2 + 12m
h(m ) = 10 + 3m

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.
