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

what hsc mark would 58/70 be?

 

[Dellrune]

stoked easy exam! might lose 1 mark on the final question since my wording was kind of poor. Hopefully zero sillies since i checked twice

 

[kawaiipotato]

Was c = 5, a = 2, n = sqrt11 /2?

I believe that's a definite E4 - probably low to mid-90's.

yes

 

[thecondimentman]

pretty sure that's what I had. Can't remember exactly what "a" was

 

[apurba]

what will 66/70 align to?

 

[SNT k]

what did people get for question 8?

 

[jakewist]

Was c = 5, a = 2, n = sqrt11 /2?

Wow E4 def guaranteed

 

[SNT k]

the limit question with sin(x-3) on top?

 

[thecondimentman]

I did 1/5, bit of a guess

 

[Mathsisfun15]

Out of curiosity would 70/70 always align to 100 since they separate state ranks by your working do they separate 100 on working

What is the height of the mountain or whatever in the 3d trig quesiton?

 

[Thjv]

what did people get for question 8?

its known that sinx/x = 1

so lim x-> 3 1/(x+2) = 1/5

100

There's probably a low 100 and a high 100

 

[SNT k]

i got 910

 

[Drsoccerball]

its known that sinx/x = 1

so lim x-> 3 1/(x+2) = 1/5

lel or you can sub it in your calculator 2 seconds...

 

[kawaiipotato]

Wow E4 def guaranteed

How did you go m8?

 

[Thjv]

lel or you can sub it in your calculator 2 seconds...

took me 1 second to do it in my head..
