Assume four row
Write a single line of code to answer each of the following questions. You may use the results of any question to answer subsequent questions if desired. Note that your solutions should work regardless of the number of elements in the four vectors.
- a. Create a new vector AvgProd that contains the total number of each item produced during the four-year period. Note that TotalProd will have the same number of elements as the original four vectors.
- b. Create a new vector AvgProd that contains the average number produced per year of each item during the four-year period. Note that AvgProd will have the same number of elements as the original four vectors.
- c. Create a four-element column vector YearProd that contains the total number of all units produced during each year, 2010 production should be in the first (top) element.
- d. Determine the maximum number of any type of device produced during each year and place the results in a four-element column vector MaxProd.
- e. Determine the maximum number of any device produced during any year and place the result in the scalar OverallMax.
- f. If your company makes a profit of one-fifth of one cent on each device produced, regardless of type, determine the total profit made during this four-year period and place the result in Profit. Your result should be in dollars.

Row indexing: Snow fall records
stateSnowRecord contains the amount of snow fall (in cm) for various cities. Rows represent a city and columns represent the snow fall
for a given month. Assign citySnow Record with all elements of row rowNum.
Ex: If stateSnowRecord is [17.3, 20.3; 4.8, 6.2] and rowNum is 2, then citySnowRecord is [4.8, 6.2].

I would like it to be solved using scalar method. We dont use 3D in this course. We only use scalar analysis for the relative velocity equation (writing the x and y components of the equation and solving the equations for the unknowns). I have attached a sample question with solution in order to get an idea on how to use the scalar method to solve my question. I would like question 16-109 to be solved in a similar way.
