Use software to create a scatter plot of the data. Given the scatter plot, residuals plot, and the QQ plot, which of the five assumptions about linear regression are satisfied by this data. Check all that apply. Group of answer choices There is a linear relationship between X and Y. The variance of the error term is constant for all values of X. The residuals are Normally distributed. The X values are measured without error. The observations are independent.

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)) =
