Answer
Explanation:
Step1: Calculate the weighted - score for tests
Multiply test grade by its weight: $77%\times15% = 0.77\times0.15=0.1155$
Step2: Calculate the weighted - score for labs
Multiply lab grade by its weight: $56%\times7%=0.56\times0.07 = 0.0392$
Step3: Calculate the weighted - score for assignments
Multiply assignment grade by its weight: $42%\times7%=0.42\times0.07=0.0294$
Step4: Calculate the weighted - score for the final exam
Multiply final - exam grade by its weight: $84%\times71%=0.84\times0.71 = 0.5964$
Step5: Calculate the final grade
Sum up all weighted - scores: $0.1155 + 0.0392+0.0294 + 0.5964=0.7805$
Answer:
$78.05%$
