The interval [0,4] is partitioned into n equal subintervals, and a number xi is arbitrarily chosen in the ith subinterval for each i. nlim n→[infinity] Σ (6xi-2)/n i=1

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
