I got lambda as 3/4, and the length as 221m. The angle one I flopped completely, and the marbles one was just awful

Anyone else get lambda as 57/77 in the vectors mountain question or have I gone seriously wrong?

Also, I got 4.44 radians for the angle and have no idea about that weird summation question

Does anyone remember the marks for each question? so i can work out what i got

I got lambda as 3/4 also, can't remember the length I got but I would think I got the same.

Also, for the next part of that question, it seemed a bit ambiguous as to what a "significantly shorter" distance was?

What did people get for a in the last question?

I got a=0.6, although I only recognised that last minute and wasn't able to change all my other answers in time using the incorrect value of 'a' I had previously :frown:

Does anyone remember the exact question for the volume of rev. one?

I just worked out the distance of OP and OQ, showed that they were both greater than 221m, and then stated that they should build the new tunnel

Question 9 was 8 marks, question 4 was 5 marks, question 5 was 8 marks. No idea about the rest.

Original post by Ejaz_U

Question 1 - around 6/7 marks
Question 2 - around 5/6 marks
Question 3 - 6 marks?
Question 4 - 7 marks?
Question 5 - 5 marks
Question 6 - I forgot :confused:

Question 7 - 8 marks?
Question 8 - 8 marks?
Question 9 - 10 marks?
Question 10 - 9 marks?

I'm probably really inaccurate with the marks :tongue:

Yeah that’s correct, I got my distance being in the 220s as well. My λ was 1/4

That was pretty much the only question I was alright in, everything else was shambolic :frown:

Can’t believe I didn’t get the vector question because I didn’t find k..

I almost lost my marbles with that standard deviation q, until I realised it was given in the formula book.

That was way harder than I expected. Glad it's not just me.

My highlight was when I found a standard deviation of sqrt(-6800). The other questions I think I did decent on, apart from chimpanzee.

not really, only the last one and a couple of the others - it tested your understanding not just whether you could apply some equations to various things
