Please help with the following questions, I have attached the tables

Using the values in the Exam MLC Table and assuming uniform distribution of deaths, calculate the mean and variance of the following values: 1) A, 40:25 2) A 40:25 3) A 40:25 4) A 40 5) A 40:25 6) A 40:25 7) A (12) 40 8) A (12) 40:25 Show that the following equations are true by calculating the individual pieces from the Exam M Table and showing both sides of the equation are numerically equal: 1) A = v940 + VP404 40 41 2) A = - 1940 + VP 40-4 40 41
