Problem 55245. Calculating Student Grades

The matrix grades contains raw grades for 7 students who took your course. Each row represents a different student. The first 7 columns contain grades from 7 homework assignments, the next 3 columns contain grades from exams, and the last 5 columns contain grades from quizzes. If a student missed an assignment, their grade was recorded as 0.
The final grade for each student is calculated using the average of their raw scores weighted by how much each assignment type is worth. An example rubric would look something like:
r = [0.2 0.45 0.35]
which indicates that homework, exams, and quizzes are worth 20%, 45%, and 35% of each student's final grade, respectively.
Write a function that takes a rubric vector as an input and outputs the final grade for each student.
