question 32

Multiple Choice

Solve the problem.
-A math course has 4 exams weighted 15%, 10%, 20%, and 55%, respectively, toward the final grade. Suppose that a student earns grades of 75, 84, 92, and 86, respectively, on the four exams.
The weights are given in matrix W and the test grades are given in matrix G. Compute WG and Interpret the result.
$W=\left[\begin{array}{cccc}0.15 & 0.10 & 0.20 & 0.55\end{array}\right], \quad G=\left[\begin{array}{c}75 \\84 \\92 \\86\end{array}\right] \begin{array}{c}\text { Test 1 } \\\text { Test 2 } \\\text { Test 3 } \\\text { Test 4 }\end{array}$

• A) \([ 50.55 ]\); The value \(50.55\) is the student's overall course grade.
• B) \([ 85.35 ]\); The value \(85.35\) is the student's overall course grade.
• C) \([ 80.15 ]\); The value \(80.15\) is the student's overall course grade.
• D) \([ 84.25 ]\); The value \(84.25\) is the student's overall course grade.
