Suppose that the cost of producing 2 tablets is defined by c(x) = 200 + 10x + 0.22where x represents the number of
tablets produced. The graph below represents the function.
b
(25,575)
(20,480)

15 20 25 30
Part A: Find the average rate of change over the interval [a, b].
Part B: Find the average rate of change over the interval [b, c).

What is the interquartile range of this data set? 2, 5, 9, 11, 18, 30, 42, 48, 55, 73, 81

Ineed with math stuff it involves graphs

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.
