Question

In a weighted average, some values are worth more than others in computing an average value. A teacher gives a quiz, a test, and a final exam. The expression $\frac{q+3t+5f}{9}$ gives the weighted average of the scores where $q$ is the quiz score, $t$ is the test score, and $f$ is the final exam score. What is the weighted average for a student who scores 86 on the quiz, 75 on the test, and 80 on the final exam?

Answer 1

The weighted average score of the student is 79

Explanation:

Here, we want to calculate the weighted average score for the student.

To calculate this, we shall be using the given expression;

The expression to calculate the weighted average score is given as;

(q + 3t + 5f)/9

Thus using the scores of the student, we have;

(86 + 3(75) + 5(80))/9

= (86 + 225 + 400)/9 = 711/9 = 79
