A research group is on a college campus and is conducting a survey regarding the coffee consumption of college students in America. They randomly select three sample groups of 100 registered students to complete their survey,
which asks the students to identify the average number of 8-ounce cups of coffee they consume each day. The results
of the three sample groups are shown in the table below.
0 1 2 3 4+
Sample #1 38 19 26 16 1
Sample #2 32 14 37 15 2
Sample #3 41 22 31 6 0
One researcher looked at the results and made the following inference: "More college students don't drink coffee than
do." Is this a valid conclusion? Explain your reasoning using complete sentences.

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)) =
