Yeah I did.

Thought the paper was pretty standard, nothing horrible. Though there were some tricky questions where it required logic more than anything (like the swimming pool with the 2 circles).

How did you find it?

Binomial - 61236 is the term independent of x

Area under graph = triangle + area under curve between 0 and 4.

= 10 2/3 sq units! :smile: (or was it 10 1/3? It was one of those :biggrin:!)

I just left it as 61,236
I don't see how they can penalize for not writing to 3.s.f when 61,200 is NOT the term independent of x! haha
My teacher went through the binomial expansion and all the answers we're saying are the agreed answers between me and the people in my maths class. We should do well! :biggrin:

I feel that the test was a bit easy, had problems with 7 (Binomial Distribution), and was just curious what every one got for the height of the strip for the trapezium rule. I got 2, but not entirely sure if it's correct or not.

Yeah I got 114 as well! An A will probably be 80%! The test wasn't very hard nor very easy so it should stay around 80%

Yes the height of a strip was 2 so when you subbed it into the formula the 'h/2' turned into '1'.
I also got 114 metres for that question :smile:
