The grades of 3 students in a test are 95, 92,80 respectively; in projects are 100, 80 and 90;homework 100, 100 and 90; and in the quiz are 75;80and 90. The tests are 40% of the grade, projects 15%, homework 25%, and quizzes 20%.. Organize the data in a matrix and perform necessary operation to find the final grades of the 3 students. Use MATLAB to verify the answer. An outbreak of a virus hit the local public schools. Approximately 15% of the male and female juniors and 25% of the male and female seniors are currently healthy, 35% of the male and female juniors and 30% of the male and female seniors are currently sick, and 50% of the male and female juniors and 45% of the male and female seniors are carriers of virus. There are 100 male juniors, 80 male seniors, 120 female juniors, and 100 female seniors. Using two matrices and one matrix equation, find out how many males and how many females (don't need to divide by class) are healthy, sick, and carriers.
