Stocks The table presents the 2016 percentage change in the stock price
for six well-known companies. (Data from: finance.yahoo.com.)
Company | Percentage |
America Express | +10.6% |
Coca-Cola |
|
ExxonMobil | +14.9% |
Hewlett Packard | +63.1% |
Ford |
|
Red Robin Gourmet Burgers |

Suppose that we wish to determine the difference in percentage change between two of the companies in the table, and suppose that we are interested only in the magnitude, or absolute value, of this difference. Then we subtract the two entries and find the absolute value. For example, the difference in percentage change of stock price for American Express and Ford is
Find the absolute value of the difference between the two indicated changes in stock price.
Hewlett Packard and Red Robin

Show the coordinate axes (x and y). Choose the scale yourself and show it in the flowchart. Create a flowchart based on the algorithm. Write the program code in Python. Additional requirements: Each stage must be clearly shown in the flowchart. The program must plot the graph and save it in PNG format. Write the code in a modular way (functions and main section should be separate). Expected results: The graph of y=xsinx will be plotted in the interval [ 0 ; π ]. The algorithm and flowchart will be understandable and complete. When you test the code, a graph file in PNG format will be created.arrow_forwardA company specializing in lubrication products for vintage motors produce two blended oils, Smaza and Nefkov. They make a profit of K5,000.00 per litre of Smaza and K4,000.00 per litre of Nefkov. A litre of Smaza requires 0.4 litres of heavy oil and 0.6 litres of light oil. A litre of Nefkov requires 0.8 litres of heavy oil and 0.2 litres of light oil. The company has 100 litres of heavy oil and 80 litres of light oil. How many litres of each product should they make to maximize profits and what level of profit will they obtain? Show all your workings.arrow_forward
