The amount of money spent by a customer at a discount store has a mean of $100 and a standard deviation of $30. what is the probability that a randomly selected group of 50 shoppers will spend a total of more than $5700? (hint: the total will be more than $5700 when the sample average exceeds what value? ) (round the answer to four decimal places.)

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
