I just... I cant... I don't even know what to say

 

[kawaiipotato]

it was easier than what I expexted zzzzz anyone can explain the last probability?

Which part?

 

[Drsoccerball]

Hey be careful bro, it was 2^(2n) so you had to multiply by 2^(2n +1)

Sorry I didnt remember the question that well yes that was right.

Did you screw up?

 

[TQuadded]

Finally someone who can make me feel better

The people who thought it was easy probably did 4-unit. The people who just did 2-unit and 3-unit would've found it hard - exhibit A and B.

FML.

found it alright hoping for 80% - probability fucked me up the bum and the v^2 graph was a bit of a mindfuck with part iii) trying to find it all - if someone knew the answer to that it would be really cool! thank you!

Agreed... Alot of non extension 2 students couldn't obtain the result required.

inb4 100%

 

[Mathsisfun15]

inb4 100%

Yeah he was probably referring to it being too easy

 

[diggery]

Gg its root11/2

why is it root11/2 ? Wasnt the graph v^2 against x?

 

[thomasdo1]

I'm starting 4u nextweek, would I have done better in the exam knowing 4u?

 

[Kaido]

Hmm, I just let v=0 and solved it that way

 

[Thjv]

I'm starting 4u nextweek, would I have done better in the exam knowing 4u?

Not really.

 

[TQuadded]

I'm starting 4u nextweek, would I have done better in the exam knowing 4u?

Not necessarily, but some things in 4-unit can be used to make 3-unit more efficient.

 

[Drsoccerball]

Hmm, I just let v=0 and solved it that way

Since c=5

 

[atargainz]

I'm starting 4u nextweek, would I have done better in the exam knowing 4u?

nah, they're referring to the candidature. 4u kids are often more mathematically capable and will do better

 

[diladial]

thank you to those who answered the probability- lost all 4 but hope no where else ))

 

[authenticity]

I'm starting 4u nextweek, would I have done better in the exam knowing 4u?

Maybe. If you're capable of doing 4u (particularly the harder 3u area), then you should be able to tackle those corresponding topics in 3u.

 

[TQuadded]

Whatever, it was only one unit anyway. Now I just need to get at least an 80 raw mark for Physics...

The probability A wins was 1/2 so you find an equation for probability up to n and then multiply both sidens by 2^(n+1) to obtain the answer.

Actually I think you multiplied by 2^(2n+1) in the end
