This is par for the course for Comcast subscribers, who also haven't been able to watch HBO Go on the Playstation 3 since that app arrived a year ago. Comcast doesn't support HBO Go on Amazon's Fire TV devices either, and only started working with Roku last Decemberâmore than three years after the app became available.his is par for the course for Comcast subscribers, who also haven't been able to watch HBO Go on the Playstation 3 since that app arrived a year ago.

Weighted average calculation. The weighted average (x) is equal to the sum of the product of the weight (wi) times the data number (xi) divided by the sum of the weights: Example. Find the weighted average of class grades (with equal weight) 70,70,80,80,80,90: Since the weight of all grades are equal, we can calculate these grades with simple average or we can cound how many times each grade apear and use weighted average. 2Ã70,3Ã80,1Ã90.
The weighted-average method (also called the average cost method) provides that the average unit cost is included in the cost of goods sold. Weighted-average (average cost) inventory costing method assumes that the average cost of inventories is to be recognized as the cost of goods sold.In order to determine the weighted-average, you need to add all costs of items on hand and divide the result by the number of items.In our example, the calculation is as follows: ($5,000 + $5,500) Ã· 2 = $5,250. This amount will be charged to the cost of goods sold when an item is sold.n order to determine the weighted-average, you need to add all costs of items on hand and divide the result by the number of items.
