- How to solve this Use the fastfood.csv file to complete the following assignment. Create a file, fastfood.py, that loads the .csv file and runs a regression predicting calories from total_fat, sat_fat, cholesterol, and sodium, in that order. Add a constant using sm.add_constant(data). Then, print the following to two decimals print(model.mse_total.round(2)) print(model.rsquared.round(2)) print(model.params.round(2)) print(model.pvalues.round(2))Q2: There are three buckets size X, Y, M (1<=X<=Y<=M). All three buckets are initially empty. Using these three buckets, we can perform any number of the following two types of operations. We can fill the smallest bucket (of size X) completely to the top with X units of water and pour it into the size-M bucket, as long as this will not cause the size-M bucket to overflow. We can fill the medium bucket (of size Y) completely to the top with Y units of water and pour it into the size-M bucket, as long as this will not cause the size-M bucket to overflow. Although we may not be able to completely fill the size-M bucket, but we can still determine the maximum amount of milk we can possibly add to largest bucket. Sample input: 17 25 77 Sample output: 76 In this example, we fill the bucket of size 17 three times and then bucket of size 25 once, accumulating a total of 76 units of water. You could use additional test case to test your program: Input: 52 791 877 Output: 843 Input: 26…Matlab: How do I plot semilogx() multiple times?

If you think the system is in an unsafe state, write "unsafe" in the answer box, otherwise, write the process sequence that satisfies the safe state. While answering the question write only the id of the Tasks separated with comma, (e.g., for sequence <T4,T2,T1,T0,T3> write only 4,2,1,0,3 ).Prove the validity of the following arguments: “Every laptop has an internal disk drive. Some laptops have a DVD drive.
