What is weighted average atomic number
What is a time weighted average?
Time Weighted Average is an average using time as the weight. For example assume 3 gallons flows for 5 minutes then 10 gals for 5 mins then 7gals for 15 mins. The time-weighted average of flow over the total time is [(3x5)+(10x5)+(7x15)] all divided by (5+5+15) and equals 5 gallons per minute.
What is the weighted average of the following 2 2 2.5 3 3 4?
In addition to the observed values, a weighted average needs weights. No weights are given.
Definition of weighted average?
A weighted average is the average of a particular category and then weighted to whichever percentage it represents. Ex. Your course grade consists of 50% tests and 50% homework. You take two tests. You would take the average of the two tests and then weigh them against the total, which is 50%. (G1+G2)/2 x 50%
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
