If 85 percent of a grade is 80 and the other 15 percent is 91 what is the final grade?
You have what's known as a weighted average. The 80 score is weighted more heavily than the 91 score, so the weighted average will be closer to 80 than a non-weighted average. 0.85 x 80 = 68 0.15 x 91 = 13.65 68 + 13.65 = 81.65
How do you get weighted mean?
A weighted mean is when some values contribute more than others. In order to calculate weighted mean multiply each weight by its value, add those and then divide by the sum of the weights.
Is there any difference between expected value and arithmetic mean?
There is. Arithmetic mean is simple average of numbers not weighted by anything. However in EV, the numbers are weighted by their probability
If you have a 47 in your math class and you got a 85 on your math project what is your grade?
Depends upon how the project is weighted compared to the rest of the course.
What does Current Grade Period Weighted Average mean?
You have to multiply your score and then divide

If you get an A in my GCSE textiles coursework and an A in the exam what will it average out to?
If your textiles coursework is weighted as 60% of your final grade and the exam is weighted as 40%, an A in both would average out to an overall grade of A.
How can you find out your final grades?
Go on your schools website.ORgrade in class = (exam grade)(amount weighted i.e. 0.2) + (class grade)(amount weighted i.e. 0.8)To find out what you need to get on your exam to get a certain grade in a class:(desired grade in class - (class grade)(amount weighted i.e. 0.8)) / (amount exam in weighted i.e. 0.2) = needed exam gradeFor instance, if you want to make sure you get a 93% overall and you got a 95% so far, and you know that the exam will be 20% of your overall grade:(93 - (95)(0.8)) / 0.2 = 92.5So, to get a 93% in the class you must get an 85% on your exam.

The weighted mean is a special case of the?
Geometric mean
Is it the arithmetic mean or weighted mean that is more accurate Why?
The arithmetic mean and the weighted mean are used in different situations. The arithmetic mean is used in frequencies as a general average. The weighted mean is used when different factors contribute to some kind of total for example with weighted index numbers. It is not a matter of accuracy it involves using the right mean in the right situation. Almost always (if not always) a question will specify which mean to use.
What is the definition of 'weighted mean'?
"Weighted mean" is the average calculated by taking into account not only the frequencies of the variables but also some other factors such as their variance.
