Atire company finds that the lifespan for one brand of its tires is normally distributed with a mean of 47,500 miles and a standard deviation of 3,000 miles. if the manufacturer does not want to replace more than 5% of the tires, what should be the approximate number of miles for the warranty? use a ti-83, ti-83 plus, or ti-84 calculator, and round your answer to the nearest integer.

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.

Plz hurry evaluate the expression a+b where a=8 and b=19
