A weighted average multiplies each data point by an arbitrary 'weight' and divides by the sum of the weights. Your everyday garden variety average, or arithmetic mean, is actu…ally a special case of a weighted average, except all the weights are equal to 1. Selection of weights are largely arbitrary but generally based on sound reasoning (e.g. relative population sizes). As another example, let's say you have 5 reviewers of a product giving their overall satisfaction rating. The scores are 9, 7, 6, 7, 3. However you have a very high regard for Reviewer 1 so you assign her a weight of 15 (and the others remain at weight=1). The average score is (9+7+6+7+3)/5=6.4 The weighted average score is (15*9+7+6+7+3)/(15+4)=8.3 The weighted average is much closer to Review 1's opinion due to your weighting decision. The weight is often NOT arbitrary as in the above example. If a bank wants to know the average interest rate for its portfolio, the weight is the principal balance of each loan. If there are only two loans, one for $999,990 at 6% and one for $10 at 12%, the AVERAGE RATE is 9% [(6 + 12)/2]. However, the weighted average rate is only 6.00006% [(((.06*999990)+(.12*10))/1000000)].
Answer Electronic computers in the sense that we know them today did not exist in the early 1940s. When the first digital machines were developed near the end …of WW2 they were either very specialized calculating machines and so did not have a "typical" configuration, or were enormous, room-sized devices weighing many thousands of pounds.
It varies from a few pounds to large, heavy units. You can fling around some laptops easily with one hand, and some computers can only be moved with lifting equipm…ent. You'd have to ask about the weight of a specific computer.
Indeterminate. Depending on cost and purpose modern computers weigh from grams to many tons.
The average weight of a laptop is bout 6 pounds. That's about 2.72Kg
Simply add up all of the data you have. Then find how many pieces of data you have and divide the first number by this number. Example: 5 bits of data: 1 5 6 9 4 Ave…rage is (1+5+6+9+4) divdided by 5 = 5
Number-average molecular weight of a polypropylene is 1000000 gmol Compute the number-average degree of polymerization?
i got 23765.4
Depends on whether you're referring to male or female! See the related link for average weight information, and other average body statistics.
the average atomic mass is computed by summing all isotopic weights of the isotopes of that element and then dividing this by the the total number of isotopes of that el…ement (note that isotopic mass is exactly the same as atomic weight, except for isotopes).
Explain how both a stock split and a stock dividend affect the computation of the weighted average number of shares outstanding?
Stock splits and stock dividends both affect the Weighted Average Number of Shares Outstanding in the same way. When it occurs, you act as if it happened at the beginning of …the year, and throughout previous periods.

Average cost for 'good' computers can be estimated at around 800 (to 1000) dollars...
What is defined as a computer is a rather gray area. In 2010 customers who bought a computer from Wal-mart were 90% first time PC purchasers. generically between desktop/lap…top availability $650 would be a safe average. There are also extreme outliers. Systems that go for $2,500 - $3,500 these few extreme units draw the average higher.
In 2010, the average price of a computer was $615.
