The sum of the ages of a wood plaque and a bronze plaque is 20 years. four years ago, the bronze plaque was one-half the age of the wood plaque. find the present age of each plaque.

Given the graphed function below which of the following orders pairs are found on the inverse function

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.

Complete the conditional statement. if a + 2 < b + 3, then a < b b < a a – b < 1 a < b + 1
