Thanks !!! :)

Another q: log(B7)2= 0.36 log(B7)5= 0.83 find log(B7)14 :)

Aweskim, Thanks for these! :)

Thanks :). What about Find the derivative of log(little3)(2x+5) ----> I don't know if the 3 is a base or just 3 but its small and looks like a base.

hii, thanks for this!!! but what do i open it witth?

Next Q. Find the stationary point on the curve y= lnx/x and determine its nature. How do i dy/dx this? AND Find the derivative of log(little3)(2x+5) ----> I don't know if the 3 is a base or just 3 but its small and looks like a base.

Thanks, i figured my mistake :)

Ok. So i will get, well i got y= 1oge(101/19). True?

1. find the equation of the tangent to the curve y=loge(5x+4) at the point where x=3. How do i do this? Show working out too please :) First i y' it so i got...>> 5 ---------- 5x+4 Do i sub x=3 in now? So i will get...

I have working out for myself and onlookers :) I got external aid and I shall post it. This Q. is under tree diagrams but i really fail at them. For B) P( 1 gov. or none)= P(GN) + P(NG) = (0.42*0.12) x 2 <--cos two situations and answer is 11% C) P(GG) =...

I figured out A) Its P(OO)= 0.42^2 = 17.64% :)

I did, it looked weird and wrong...

In a certain poll, 46% of people surveyed liked the current government, 42% liked the opposition, and 12% had no preference. if two people from the survey are selected at random, find the probability that A) both will prefer the opposition B) one will prefer the government and the other will...

Thank you, your a life saver!

:santa: YOUR RIGHT ! How'd you do it, can you explain it to me? first and 2nd and whats the C?

:( Sorry but its not. Answers are a) 84681/1000000 b) 912673/1000000 c) 27/1000000>>>>>> I figured this one out but the not rest- a and b

So, I can e-mail you if i need help on any of my HSC modules? Im doing the A now. Can i have your e-mail please :)

In a batch of 100 cars, past experience would suggest that 3 could be faulty. If 3 cars are selected at random, find the probability that: (a) 1 is Faulty (b) None are Faulty (c) All 3 cars are faulty Can you show working out too? Its under tree diagrams but you can just use fractions :)...

Oh ok, sure i get ya :)

But what do you mean by the 2^x >0 for all x? Why?
