I said the median for the men's results was higher, which means men have generally scored higher; and IQR for women's results was smaller, so women generally have more consistent results.
For the congruent triangles I used the fact that two sides and the angle between them are equal in both triangles (10 cm and 135 degrees). Anyone done that?

How is the final mark estimated? Do they sum the score on the non-calc and the calc paper, or they are accessed individually? The fact that I have to wait until August makes me a saaad panda :frown:

yeah I got 135 degrees to!
Think they add both papers?

Pretty sure the semi circle was 25.5cm
Circumference = 2nr
= 10n
= 31cm
31/2= 15.5
Base= 5+5=10
15.5+10= 25.5cm2

Crapp I put 12&14 just realised nowww

Don't worry, I think we've all made silly mistakes!
anyways What do you thing grade boundaries will be like?

It's the sum of the 2 papers but the calc is worth 60% :smile:

I did what you did for the congruency.

Thoughts? I did okay except for a couple of mistakes I made, and I couldn't do 18b) the very last question. The frustum was 875 wasn't it?

18b was the hardest, did you relate your workings to the midpoint of the xaxis involved in the graph? also i got h=1 for part a; anyone else get that ?

That paper was horrible! What did everyone put for what T was in the journey question.. I put 3.5 OR something like that....

yh 3.5 was right anyone get the surd triangle question, i think i did, but im not sure

I managed to reach 5 using the Area formula and them randomly divided it by 2 to make it 2.5cm :colondollar:

(some marks for working hopefully)

I am also sure about the semicircle's perimeter - 25,5 cm.
For 18b I got highest point at 64/15, or 4(4/15) by setting the x variable at middle of horizontal distance (3,5). How many marks was the first part of the question worth? I got that wrong.

guys what do we with the grade boundaries will be like?
I made loads and loads of stupid marks!
how did people calculate the surd question it was so hard!
how was it 3.5 for 18b? it said that it was 7.5?
Also im pretty embarrased but i got the cd and dvd q wrong?
I got one of them £10 but i got the other one wrong
How many marks do you think i will get for this q?

Did anybody else get 40cm2 for the area of the parallelogram??

I am not sure anymore (tend to forget really fast). Wasn't the maximum distance for 18b 7 meters? The question was to prove that the maximum point is at 4(4/15)m. The equation for the height was -1/15(2x+1)(2x-15) as far as I remember.
