75/120 a band 5???????imprsiv said:96-99/120 shuld give u a band 6
75/120 will be around a low band 5 aligned

Question isn't really that bad...it ust requires a bit of intuitive thinking that isn't usually honed in 2unit maths....MX1 people will find it easier because we're used to having to think outside the box to answer a question. Question 10 is just a lock that, once you find the key, falls apart quite easilyforevaunited said:Isn't it all relative to how the state goes? If its a really easy test and a high percentage of people get above 95 or 100, wont that mean they have to scale/align/(i dont know the correct terminology) down? hmm im not really sure on that.
and whoever said that question 10 is a bitch - i second your statement. i very rarely get them. but the thing is most of em just require incredibly long calculations and differentiating something that takes up a whole page. extremely boring and time-consuming maths - makes me angry.
Totally irrelevant as the system changed in 2000. Before that the mean and SD was kept the same each year in each subject.Forbidden. said:Source (Primary): Board of Studies - Examination Statistics 1988-2000

I bet the constants are the case of this.samuel slack said:mkay. the volume of a cone is 1/3 pi r^2h right?
Well. This is what I ended up with, its definitely gone wrong somewhere.
pi [(2rh)^3)/3h]... where'd I go wrong?
How we think alike !morganforrest said:Yep easy....square top and bottom...take r^2/h^2 out the front of the integral, since these are constants, as well as the pi u multiply by since its a volume of revolution....integrate x^2 expand, you get 1/3pi^3....then multiply it by the pi.r^2/h^2 and simplify to get 1/3.pi.r^2.h( formula for volume of a cone)
mmkthxbai :wave:
But I <3 integral calculus...sequences and series is my bitch :burn:
They don't HAVE to as such, but it makes it a whole lot easier to see what you're meant to integrate and what you just leave....some people would make the mistake of integrating the r and h so bringing it out the front just keeps the algebra/calculus simplersamuel slack said:Okay. So before I do any integrating constant have to be brought outside the integral? Very nice... I get it.
