ok so i have a fish bowl and people have been telling me get a better tank with a filter so it keeps the tank clean and my goldfish will live longer. so if anyone has this tank can you please explain everything e.g filter, light, bubbles?
and could i turn the bubbles shooting up off at night so i can get to sleep lol
Answer
Well biorbs technically come with an undergravel filter, however to be honest they are overpriced novelty crap. Also they are too small for goldfish.
Fancy goldfish would need a 20 gallons tank (and 10 gallons for each additional) with filtration rated for twice the tank size.
Common/comet/shubunkin goldfish need 50 gallons each with filtration rated for twice the tank size.
Good luck finding a biorb that size....
Light - With goldfish is more for your viewing pleasure (they will kill most plants so thats out of the question).
Bubbles - Useless, forget it. (exception: if a filter is run by an airpump ex. sponge filter then the airpump has to be on 24/7).
Filtration - goldfish are heavy waste producers and need heavy filtration (one that is rated for twice the tank size, like 40 gallon-rated filter or 2x 20 gallon-rated on a 20 gallon tank). The purpose of filtration is to establish a host of beneficial bacteria which turn toxic fish waste (ammonia) into relatively harmless nitrate. Since you already have the fish you would have to do a fish in tank cycle:
1) Fill the tank, check if the filter work.
2) Add dechlorinator (i recommend seachem prime)
3) Give the tank 12 hours for the water to settle.
4) Put the fish in
5) Monitor the water for ammonia, nitrite and nitrate daily.
6) Do a 50% water change should ammonia or nitrite start approaching 1.0 ppm (or even less)
7) After few weeks the bacteria will develop, first culture which turns ammonia into nitrite (which is also toxic) and then another which turns nitrite into nitrate (which is relatively harmless unless at high concentration). Once you get a reading of 0 ammonia, 0 nitrite and some nitrate the tank is finally "cycled" and 25% water change once a week should be enough. (Aim for nitrate below 20 ppm)

Finding Mean in Stats:?

How do I find a mean like this?
THe probability of a baby boy being born is .513. Mass Gen plans to monitor the genders of the next 1000 babies that are boen:
Find the mean number born in the randomly selected group of 1000 babies
Next, find Stand. Dev.
Please help!
Answer
As the baby can only be one thing or the other
(boy or girl), it represents a binomial distribution.
X~B(n,p)
*Mean=np
Mean= 1000 x 0.513
Mean=513 boys
*Variance= np(1-p)
Var=513x(1-0.513)
Var=513x0.487
Var=249.831
*Standard Deviation=square root of var
S.D= 15.8 (1dp)
