Final Exam Grade Calculations

The video tutorial explains how to calculate a weighted percentage for a course grade. It uses an example where a student has an 84 average before the final exam, which counts for 25% of the course grade. The tutorial demonstrates how to calculate the best possible course grade if the student scores 100 on the final, resulting in an 88% overall grade. It also shows how to determine the minimum score needed on the final to achieve a 75% course grade, which is 48%. The video provides a clear explanation of the weighted percentage calculation process.

What is the initial average score of the friend before the final exam?

• 84

• 100

• 75

• 88

What percentage of the course grade does the final exam account for?

• 75%

• 25%

• 50%

• 100%

If the friend scores 100 on the final, what is the best possible course grade?

• 100%

• 88%

• 84%

• 75%

How is the current average of 84% expressed as a decimal?

• 0.84

• 0.75

• 1.00

• 0.25

What is the decimal representation of the weight of the final exam?

• 0.84

• 0.75

• 0.25

• 1.00

What is the overall grade the friend wants to achieve?

• 88%

• 75%

• 100%

• 84%

What equation is set up to find the minimum score needed on the final?

• 0.88 = 0.75 * 0.84 + x * 0.25

• 1.00 = 0.84 * 0.25 + x * 0.75

• 0.84 = 0.75 * 0.25 + x * 0.75

• 0.75 = 0.84 * 0.75 + x * 0.25

What is the result of 0.84 multiplied by 0.75?

• 0.63

• 0.75

• 0.84

• 0.25

What is the minimum score needed on the final to achieve a 75% course grade?

• 48%

• 75%

• 63%

• 88%

What is the final step in solving for the minimum score needed on the final?

• Divide by 0.25

• Multiply by 100

• Add 0.25 to both sides

• Subtract 0.63 from both sides
