The youth from a local church are having a breakfast fund-raising event. They are planning on serving biscuits, pancakes, and waffles. The ingredients for one batch of each and their requirements are given by matrices A and B. a. Calculate matrix BA. b. Interpret the meaning of each entry of matrix BA. i Click the icon to view matrices A and B a. BA = (Type an integer or simplified fraction for each matrix element.) b. Select the correct choice below and fill in the answer boxes to complete your choice. O A. With the given ingredients, batches of biscuits, batches of pancakes, and batches of waffles can be made O B. To make the desired amount of food, cups of baking mix, eggs, cups of milk, and tablespoons of oil are needed.Find the size of matrix A. Determine whether A is a square matrix, row matrix, column matrix, or none of these. A = [- 2 0 ] The size of matrix A is Which of the following describes matrix A? Choose the correct answer below. O A. It is a column matrix. O B. It is a square matrix. O C. It is a row matrix. O D. None of these.On opening night of the play "The Music Man" at the Lewiston Civic Theater, 948 tickets were sold. The total receipts for the performance was $10,540. Children tickets cost $10 apiece, adult tickets cost $14 apiece, and senior citizen tickets cost $6 apiece. If the combined number of children and adult tickets exceeded twice the number of senior citizen tickets by 279, determine how many tickets of each type were sold. There were |children tickets, adult tickets, and |senior citizen tickets sold.The augmented matrix in row reduced form is equivalent to the augmented matrix of a system of linear equations in variables x, y, and z. Determine whether the system 206 2 is dependent or inconsistent. If the system is dependent, determine which variable is free and describe the solution as an ordered triple in terms of the free variable. 0 1 1 6 0 0 0 0 dependent O inconsistent Which variable is the free variable? OA. X OB. y O C. z O D. The system is inconsistent so there is no free variable Select the correct choice below and fill in any answer boxes within your choice O A. There are infinitely many solutions. The solutions are (x where x is the free variable. (Type an exact answer in simplified form.) O B. There are infinitely many solutions. The solutions are z) , where z is the free variable. (Type an exact answer in simplified form.) C. There is one solution. The solution is ( (Type an exact answer in simplified form.)
