Hi,
I need to calculate the average velocity of vehicles on a road within a given time frame. In essence i need some statistics about roads within a road network( one of them is average velocity) for a tune frame.
I know road occupancy details (vehicles, individual speed etc) for each road at every time instance.
Any help would be highly appreciated.
Regards.|||This, to me, a bit more difficult.
Give me some time.|||If v(i) is velocity of ith Car and t(i)is the time it runs for then the average velocity of jth Car is
V(j)=sigmav(i)t(i)/sigma t(i) i=Car index. sigma(i)=T time frame
Now considering all the cars tpgether the Average velocity will be
V=sigmaV(j)/N N=total number of Cars in time T
Repeat the same for each Road and finally take the average.

What average does one need to get into Engineering Science?
Im planning to go to U of T, and even though they say they consider people in the 80s, most of the competition is way above that. Whats a competitive average to be consdiered for acceptance?|||4.0
How do i use Average Value to find the average squared distance?
Find the Average squared distance between the points of
R={(x,y): -2%26lt;=x%26lt;=2, 0%26lt;=y%26lt;=2 } and the origin.
I have no clue how. The answer is some how 8/3.|||f_ave = [ ∫ ∫ f(x,y) dA ] / [ ∫ ∫ dA ]
In this case f(x,y) is the square of the distance from the origin, i.e. (x² + y²).
Our limits/domain has already been given to us.
f_ave = [ ∫ ∫ (x² + y²) dx[-2,2] dy[0,2] ] / [ (2 - (-2)) * (2 - 0) ]
f_ave = [ ∫ ((1/3)x³ + xy²)]{x,-2,2} dy[0,2] ] / [ 8 ]
f_ave = [ 2 ∫ ((8/3) + 2y²) dy[0,2] ] / [ 8 ]
f_ave = [ ∫ ((4/3) + y²) dy[0,2] ] / [ 2 ]
f_ave = [ ((4/3)y + (1/3)y³)]{y,0,2} ] / [ 2 ]
f_ave = [ ((8/3) + (8/3)) ] / [ 2 ]
f_ave = 8/3
R={(x,y): -2%26lt;=x%26lt;=2, 0%26lt;=y%26lt;=2 } and the origin.

How much does an average singaporean earn?
How much does an average Singaporean earn? How much is the average living cost there, including the fees for renting a house of course.
Is 3000 SGD per month enough to make a living there?
Thanks.|||If you are single 600 to 700SGGD will go on rent single room. If family, then 1200 to 1400 on 1BHK which is difficult to get. 2BHK is around 1600 to 2000 SGD.
Apart from this, 10-28 $ on mobile, 58 $ on internet connection, 50 $ on cable tv. If u r not cooking then 10$ perday on two times food. 3000 is enough to stay, but not good to save.|||That's a good one if you're single.|||The definition for poverty in Singapore is %26lt;S$800 an individual.
$3000 is pretty good considering that you'll have some promotions.|||well, sure its enough if you are single, for house rental you can try view 88db, that depends on the house, if you prefer a private property like a condominium or an apartment then the rental price is much higher, you can get cheaper rates for HDB flats or rooms|||If you are single and earn about 3000 i think it's should be enough but of course you can't live in glamorous life and you can save a lot. Because the food is very cheap here and also they do not deduct lots of taxes on your salary.
so 3000 should be OK...and can save a bit........|||if you're single...

How to Calculate the average flux of sunlight at the equator?
Calculate the average flux of sunlight at the equator. Assume that the sun supplies 1368 joule/(meter2 second) and that 30 percent of the sunlight is reflected away. Assume it is night half the time, and the sun shines directly overhead at noon. The average value of the sine function over half a cycle is 2/蟺.|||The haze and dust at near-twilight reduces incident from pure function expectations, but let's assume it doesn't, and a solar collector is flat on the ground. Obviously it's the vernal equinox. Flux density is measured in joule/meter^2, a rate, not a quantity. The average value of SIN over a half cycle is not 2/pi. The integral of SIN zero to either pi/2 or pi because symmetry is involved, in this case where K=0 and peak value is unity, is 2^-2/2. So 1368 times 70% times 2^-2/2 = 677 joule/meter^2. Isn't Calculus fun? Regards, Larry.
How much should an average 17 year old boy be able to bench press?
One of my friends can bench 57Kg, i think thats way over average though. How much should an average 17 year old boy be able to bench?|||It depends on your body weight.|||Depends on your body weight - It really does|||depends on your physical condition and your height. If you are around 1.80 m
Then you must be able to bench about 35kg.
If you are less than 1.60 then 20- 25 is good|||well me and my best friend are 16 and we can both bench more than 130 but we lift weights like 3 times a week so i guess that isnt average but maybe like 90 - 100 not to sure|||I was happy to do 200 pounds at your age. I remember when I made that mark.|||i only know how to say it in lbs but prob 100 to 130lbs more if you lift a lot. i think i benched about 190 or something. not sure about my max|||Should be able to bench atleast your body weight but dont worrie about it too much..

On average how much should a conservatory cost to install?
What are the average total costs for a conservatory installation? Nothing too grand. I will need some building work for access.|||If you get a company that specialises in installing conservatories you should multiply material cost by at least a factor of 4.|||There are lots of degreasers, at Canadian Tire. Using something at home Dish Soap or Oven Cleaner.|||Depends who's supplying it and how big it is
We've had quotes from a few of the major suppliers for a 10x12 for around 12k, so it looks to be around 1k per square metre ( includes all the foundation work)
I expect there's cheaper, but watch the quality....|||Local specialist snooted that we should compare his product with B%26amp;Q's, so we compared and bought at B%26amp;Q and have been totally satisfied with the product and the installation. Look for the end of line deals, which seem to be running on different styles at different times in the year; you will be amazed how much you can save.
