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.
Using the Weighted Average Method every unit sold would have the same Average Cost per Units Sold irrespective of the actual cost this unit is sold. For example, you sell books. The weighted average cost is $30.00 USD per book ($4500 USD/150 books according to the formula above used to calculate Average Cost per Unit).So the inventory price $30 USD will be the same for each book bought, the actual price of one book is $27 USD while another book was sold at $32 USD.or example, you sell books.
