The cost function for a telephone manufacturing plant is C(x) = 5x + 24 and the revenue function is R(x) = - 2x + 27x, where x is the number of telephones sold, in thousands.
a) Determine the profit function for the number of phones sold.
b) Determine the number of telephones sold that maximizes profit.
c) Determine the maximum profit in thousands.

Read the situations in the table below. then drag a graph and equation to represent each situation. indicate whether each of the relationships is proportional or non-proportional. edit : i got the right answer its attached

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)
