Some teachers use a weighted mean to calculate gradesEach score assigned a weight based on importanceTo find a weighted mean, each score by its weight and add Reports the For examplea student's chemistry grade is based on four sources 35% from 15% from , 25% from the midterm examand 25% from the final exam What the weighted mean given the scores shown in the table? Exam 79 Final Exam The student's score your Type an interger or a )
The weighted mean can be calculated as follows:
(0.35 x 85) + (0.15 x 90) + (0.25 x 79) + (0.25 x 85) = 29.75 + 13.5 + 19.75 + 21.25 = 84.25
Therefore, the weighted mean for the student's chemistry grade is 84.25.
To calculate the weighted mean for the given scores, we need to multiply each score by its corresponding weight and then add them up.
Let's calculate the weighted mean for the chemistry grade using the following information:
- 35% weight for the first source
- 15% weight for the second source
- 25% weight for the midterm exam
- 25% weight for the final exam
We are given that the score for the first source is 79. The score for the second source is not mentioned in the question, so we cannot calculate the weighted mean without that information. Could you please provide the score for the second source?
