Mayer High School's austerity committee wants to estimate the proportion of students that are pleased with the cleanliness of the campus. They consider two methods of obtaining a sample of 400 students from the 2,500 students at the school. Part A: To make the process easier, the committee considers surveying the first 400 students who enter the gym during the school's first pep rally. Identify the type of sampling method proposed and discuss why this sampling method might be biased. Part B: The second method the committee is contemplating involves using a random number generator app to choose a simple random sample of 400 students from a list of 2,500 student names. How could they implement this method?

Someone answer asap for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
