Question

Imagine you are in the middle of the course and you want to estimate your current grade. Note that you have not yet taken the final exam, so you should not include this in your grade. Out of 50 possible Quiz points, you have received 10. Out of 30 possible Project Assignment points, you have received 26. What is your current estimated weighted percentage in the class? Give your answer as a percentage rounded to the nearest single decimal place, e.g., if you calculate 87.56%, your answer should be 87.6 project assignments: 60% quizzes: 10% final exam: 30%

Answer 1

To calculate the weighted grade, the first step is to calculate the grade for the quiz and the project assignment.

-Quiz (Q): out of 50 possible points the student scored 10

Divide the number of points obtained by the total number of points and multiply the result by 100

$\begin{gathered} Q=\frac{10}{50}\cdot100 \\ Q=\frac{1}{5}\cdot100 \\ Q=20 \end{gathered}$

-Project Assignment (P): out of 30 possible points, the student scored 26.

Calculate the grade:

$\begin{gathered} P=\frac{26}{30}\cdot100 \\ P=\frac{13}{15}\cdot100 \\ P=86.7 \end{gathered}$

- The next step is to multiply each grade by the corresponding percentage of the grade and add both results:

$20\cdot0.1+86.7\cdot0.6=2+52.02=54.02\cong54$

The estimated weighted grade is 54
