The final grade in a particular course is determined by grades on the midterm and final. The grades for five students and the two grading systems are modeled by the following matrices. Call the first matrix A and the second B. Complete parts (a) and (b). Click to view the matrices. a. Describe the grading system that is represented by matrix B. Grading system 1 assigns 50% of the final grade to the midterm and 50% of the final grade to the final. Grading system 2 assigns 20% of the final grade to the midterm and 80% of the final grade to the final. b. Compute the matrix AB and assign each of the five students a final course grade first using system 1 and then using system 2. (89.5-100=A, 79.5-89.4 = B, 69.5-79.4 = C, 59.5-69.4D, below 59.5 = F) Grade System 1 System 2 ... Student 1 Student 2 Student 3 Student 4 Student 5 (Type A, B, C, D, or F.)

The numbers in the table stand for the number of employees working in a specific business unit and having specific performance level. An employee is selected at random. Find the CORRECT statements. Keep in mind that the mark will be reduced for incorrect answers - do not guess. All probabilities have been rounded to three decimal places. The probability that an employee is from business unit C, or that an employee has excellent performance is 0.816 The probability that an employee does not have excellent performance is 0.416 The probability that an employee has an excellent performance, given that the employee is from business unit A, is 0.404 The probability that an employee is from business unit B and has medium performance is 0.026
