For each of the following, state whether f = 0 for a main effect, the a × b interaction, or both.
(a) cell means are equal. f = 0 for a main effect. f = 0 for the a × b interaction. f = 0 for a main effect and the a × b interaction.
(b) row totals are equal. f = 0 for a main effect. f = 0 for the a × b interaction. f = 0 for a main effect and the a × b interaction.
(c) column totals are equal. f = 0 for a main effect. f = 0 for the a × b interaction. f = 0 for a main effect and the a × b interaction.

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)) =
