A dietician gathered data about the amounts of flour, baking powder, and butter used for several different muffin recipes. She used tool to organize the data in different scatter plots and found the following lines of best fit:
• The relationship between the baking powder used, x, and the flour used, y, is modeled by the equation y = 0.13x+0.92, and
correlation coefficient for the data is 0.953,
• The relationship between the baking powder used, x, and the butter used, y, is modeled by the equation y=0.24x+0.76, and
correlation coefficient for the data is 0.802,
• The relationship between the flour used, x, and the butter used, y, is modeled by the equation y=0.86x + 0.52, and the correl
coefficient for the data is 0.693.
which line of best fit can the dietician expect to produce the most reliable predictions?
A
the line modeling the baking powder and the butter used
B. the line modeling the baking powder and the flour used
C.
the line modeling the flour and the butter used
D.
All three lines will give equally reliable predictions,

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)) =
