A pharmaceutical company wants to study the effectiveness of a treatment in suppressing infection. The hypothesized rate is 3.75 infections per month. If we assume that the time until the next infection is exponentially distributed with a rate of 3.75 per month, (a) Calculate the probability that the next infection occurs within one month. (b) Calculate the probability that the next infection occurs between 0.3 and 1.7 months

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)) =
