Answer:
The correct option is B) 71%.
Step-by-step explanation:
Consider the provided information.
Mark has the following averages in his AMDM math class:
Homework: 95
Quiz average: 80
Test average: 67
Final Exam: 60
The teachers weights Homework at 10%, Quizzes at 20%, Tests at 50%, and Final Exam at 20%,
First calculate the 10% of home work as shown:
[tex]95\times \frac{10}{100}[/tex]
[tex]95\times \frac{1}{10}[/tex]
[tex]9.5[/tex]
Calculate the 20% of Quizzes as shown:
[tex]80\times \frac{20}{100}[/tex]
[tex]8\times 2[/tex]
[tex]16[/tex]
Calculate the 50% of Tests as shown:
[tex]67\times \frac{50}{100}[/tex]
[tex]67\times 0.5[/tex]
[tex]33.5[/tex]
Calculate the 20% of Final Exam as shown:
[tex]60\times \frac{20}{100}[/tex]
[tex]6\times 2[/tex]
[tex]12[/tex]
The class average of Mark is:
9.5+16+33.5+12=71
Hence the correct option is B) 71%.
