Math Wizard Wanted Inside...

According to Netcraft there almost 650,000,000 registered domains as of April 2013. Alexa has a particular site ranked at around 78,000 in traffic. So...

Dividing 78,000 by 650,000,000 is 0.00012, and subtracting that from 100 is 99.99988 ... doesn't that mean this site in question is more popular (according to traffic) than 99.99% of all the websites in the world?

Or is my formula or math incorrect? :confused:

  • I think you have it backwards, and it means less than .001%. Still, I don't know HOW netcraft gets their info, Alexa is TAINTED! COME ON! The verisign incident should have made that clear to the planet.

      No.

      It means only that it's alleged to be more popular than 99.99(8)% of websites as measured only by visitors who have the so-called Alexa Toolbar installed and running in their browsers at the time of their visits. (Those people are all internet marketers or very closely allied, I think? I don't know anyone else who uses the Alexa Toolbar).

      I have to sit here and listen to this ...

      Anyway, call me a skepchick, but I don't believe a word of it. 'Taint this, and 'taint that.

    • Steve, here's where I got the data...

      April 2013 Web Server Survey | Netcraft
  • Your Maths (<------English ) is missing a bit.

    78,000 divide by 650,000 = 0.00012 then multiply by 100 = 0.012 and subtract that figure from 100 = 99.998

    So the answer is not 99.99988 but 99.998

    Pretty much the same in the scheme of things though when the denominator (bottom bit) is this large.

    PS: My Maths teacher told me that this stuff was important and I would need it one day. I must write to my old school to inform them he was right. Once in twenty years!

  • Thanks folks.

    I'm well aware that Alexa (the service) is only an approximation based on data collected from toolbar installs. I'm also aware that the system can be gamed by website owners, but in this case I know it's not gamed.
  • If a Website ranked at around 78,000 is traveling from Phoenix at warped speed and passes a Website ranked at around 56,000 heading north just outside Albuquerque, N.M, does the draft in the wake of the Albuquerque site blow a girl's dress up or crossways?

    Seriously, this is how my brain has translated mathematical word problems since I heard the first one soooo long ago. I bow to math wizards.

    • Not my strong suit either, travlinguy, that's why I wanted to check my calculations with someone better at it than me. Looks like I had it mostly right. Forgot to multiply by 100, but as Dan (jimbo13) said, it's pretty much the same result when the denominator is that large.
    • Perhaps this will help:
      d= r X t (distance = rate X time). Now that would have helped, if you hadn't of mentioned Phoenix. This time of year, even in the late evening, air factor will, factor into it. It's damned hot there, even at 10 pm, and one can still burn their little bare feeties on the pavement.
      This is EXACTLY why this town doesn't get the rain it used to. The heat from the city pushes the clouds out! So, pavement being (depending on who poured it) having a huge factor in your "r" (rate), one would have to consider the air pressure and tread on your tires. But wait, we're talking websites: ----> Read on!

      Ok, so because Phoenix no longer gets the rain fall that they used to, some things to consider when analyzing a web ranking. (This can apply to any city, but you'll have to look up their current whether conditions and reverse engineer when needed).
      Ok.. In Phoenix the cables are not very deep, therefore, during certain months, they get super hot! Now, they cannot come inside to the cool air conditioning (c'mon, they're cables), and most are covered with rocks! .. ERGO, they cannot cool off. Dirt is a cooling agent, rocks retain heat. (You never see a horse or pig wondering around with rocks on em' .. do ya?)
      No, I'm not familiar with New Mexico, other than the famous left turn at Albuquerque, I would say this is where the "d" gets into the equation. Are the cables for internet above ground, or all below? Good grief, it can get cold-ish there!

      Ok, I'm getting frustrated, I really need more information before I can solve this math problem for you Dennis. So many variables!

      Good luck with your answer! You can also try 6.02 X 10 -23, it's the universal constant, and it may shed some light here..

  • Theresa, that's makes me...

  • Sorry Dennis! My scientific calculator's battery died. And, as we all know down here, you're only as smart as your battery! :rolleyes:

    Now don't be discouraged, I did come up with an affirmative answer it was:
    Banana

    However, I did (long ago) come up with that same answer to Miss Terra's post. I was using the same calculator.

    I wish I could've been more help!
