Need only handwritten solution only (not typed one). 5. Compute the least squares regression to fit a line to the data set{(1, 1), (1, 2), (2,5), (4,4)}.Set up the linear system Az = b. Show that it has no solution. Compute the best approximate solution x.You can use the formula x = (ATA)-¹ATb. Plot the data together with the least squares regression line (useDESMOS). Answer: y = x + .

10 boxes containing the same number of balls were in the store at the beginning of the day. During the day the number of balls sold from the second box was two times greater than the number of balls from the first box, the number of balls sold from the third box was three times greater than the number of balls sold from the first box, and so on. Finally, the number of balls sold from the tenth box was ten times greater than the number of balls sold from the first box, and in that last box, there was only one ball left. The total number of balls left in all boxes is 370 . How many balls were in each box at the beginning of the day?

A high school dietician is planning menus for the upcoming month. Anew item will be spaghetti with sauce. The dietician wants each serving tocontain at least 10 grams of protein and at least 40 grams of carbohydrates.Spaghetti contains 5 grams of protein and 32 grams of carbohydrates per cup,and the sauce contains 4 grams of protein and 5 grams of carbohydrates percup. For aesthetic reasons, the dietician wants a ratio of spaghetti to sauce to be4:1.Spaghetti costs $0.30 per cup to buy and prepare, and the sauce $0.40 per cupto buy and prepare. The dietician wants to minimize the cost per serving andkeep the calories per serving 330 or less. The sauce contains 100 calories percup, and spaghetti contains 160 calories per cup.Formulate a linear programming model for this problem.

Travis's carpet has an area of 180 square feet. He hires the CarpetPro carpet cleaning service, which is able to clean 9 square feet of his carpet every minute. Therefore, in the first minute, CarpetPro is able to clean 9 square feet of Travis's carpet (leaving 171 square feet remaining to be cleaned). In the second minute, the cleaner is again able to clean 9 square feet of carpet (leaving 162 square feet to be cleaned), etc. Which of the following functions expresses the number of square feet that still remain to be cleaned after t minutes from the time that the carpet cleaner began cleaning this carpet. A(t)=180−0.9t A(t)=180(0.1)t A(t)=180(0.9t) A(t)=180−9t A(t)=180−0.1t
