You had to put time as the variable in the GDP equation.

Also A1=14.7 not An.

Yep I got $246 too. Pretty sure that is correct.

[10weid]

if i said mean and median are both reliable as there are no outliers present will I get the mark? or dd I have to say symmetric?

I also did that.
Phew thought I lost another two marks . A little more happy now that I got 13/15 for that section.
They must have done the sum of 15 and not each one individulally im assuming?

Was this out of two?
If it was, you might get penalised for not mentioning both since my maths teacher said that both need to be mentioned for two marks. If one mark your fine

Oh my bad haha. Either way I got 246. Dunno how they got their answer then :S

[rubiks]

yeah i got 246 aswell.

what was q1biii in number patterns? itute has the answer as $30 but I don't remember writing something like that down

[Blakhitman]

I think it was maximum toll you could be charged with Toll B.

I put 30 as well.

[rubiks]

Oh yeah that's right. I put that too

[rubiks]

Also, if you put the median as 28%, range as 57% and IQR as 17% would they still give marks for that?
