- Gloria Newburg operates three self-service gasoline stations in different parts of town. On a certain day, station A sold 600 gal of premium, 800 gal of super, 1000 gal of regular gasoline, and 700 gal of diesel fuel; station B sold 700 gal of premium, 600 gal of super, 1200 gal of regular gasoline, and 400 gal of diesel fuel; station C sold 900 gal of premium, 700 gal of super, 1400 gal of regular gasoline, and 800 gal of diesel fuel. Assume that the price of gasoline was $3.20/gal for premium, $2.96/gal for super, $2.60/gal for regular and that diesel fuel sold for $3.10/gal. Use matrix algebra to find the total revenue at each station.A manufacturer of a robotic system a particular microchip, XG45D from 3 suppliers: Xullion electronics (30%), Sygus Systems (20%), and NESW technologies (50%). Historically, 3% of the XG45D chips from Xullion electronics have been found to be defective, 5% of the XG45D chips from Sygus System have been found to be defective, and 2% of the XG45D chips from NESW technologies have been found to be defective. When the XG45D microchips arrive at the manufacturer, they are placed randomly in a bin. A worker randomly selects the first XG45D microchip from the bin for installation in a robot and finds it defective. 1.1 What is the probability that it was manufactured by Sygus Systems? 1.2 What is the probability that it was manufactured by Xullion electronics? 1.3 Given that another XG45D microchip randomly picked from the bin by the same worker was not defective, what is the probability that it was manufactured by NESW technologies? 1.4 Suppose that the third XG45D microchip randomly picked…Create a scatter chart with HwyMPG on the y-axis and displacement on the x-axis for which the points representing compact, midsize, and large automobiles are shown in different shapes and/or colors.
