Liz flips a coin 40 times. The coin lands heads up 12 times and tails up 28 times. Complete each statement. The theoretical probability of the coin landing heads up is nothing ​%. ​(Type an integer or a​ decimal.) Based on​ Liz's results, the experimental probability of the coin landing heads up is nothing ​%. ​(Type an integer or a​ decimal.) The theoretical probability is ▼ less greater than the experimental probability in this experiment.

Aschool typically sells 500 yearbooks each year for 50 dollars each. the economic calls does a project and discovers that they can sell 100 more yearbooks for every $5 decrease in price. the revenue for yearbook sales is equal to the number of yearbooks sold times the price of the yearbook. let x represent the number of $5 decrease in price. if the expression that represents the revenue is written in the form r(x)=(500+ax)(50-bx). to maximize profit, what price should the school charge for the yearbooks? what is the possible maximum revenue? if the school attains the maximum revenue, how many yearbooks will they sell?
