Your company is developing a better means to eliminate cockroaches from buildings. in the process, your r& d team studies the absorption of sugar by these insects. they feed cockroaches a diet containing measured amounts of d-glucose. the cockroaches are killed at different times after eating, and the concentration of this sugar in various body parts is determined by a chemical analysis. five cockroaches dissected after 10 hours had the following amounts (in micrograms) of d-glucose in their hindguts. assume these amounts are normally distributed. 54.2, 68.3, 49.8, 21.7, 37.8 find a 95% confidence interval for the mean amount of d-glucose in cockroach hindguts under these conditions.

Someone answer this asap rn 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)) =
