Would I get a mark for calculating the midpoint for the last one, and putting the y bit equal to 0 and getting p?

I didnt see the simplification for finding the x value in 9)b) and just made my equation equal to the value given. I then used the x value given to find the y value. Would this still give me a mark?

Here are my solutions to the FP1 paper.

Reasonable paper I thought, a few tricky bits

how do I know your solutions are correct?

It is fairly easy for someone with experience to be sure of 100% or near 100% accuracy on papers of this level...also if something were incorrect someone would have noticed by now

would you be able to predict grade boundaries for this paper? :tongue:

Is Arsey a math's teacher??

Arsy Is a very smart mathematician and therefore has a very high probability of getting all the answer correct. I tested this with a 1% Hypothesis testing.

My Predictions:

74- 100 UMS
68 - 90 UMS (A* equiv)
60 - 80 Ums (A)
54 - 70 UMS (B)

nah

100 UMS - 75
90 UMS - 70
80 UMS - 62
70 UMS - 56

The 90 UMS boundary must be equidistant from the 80 and 100 UMS boundaries

if you insist:

100 UMS = 75
90 UMS = 70
80 UMS = 65

I have posted solutions to the F1 paper, I thought it was a fair bit easier than UK FP1

75 = 100ums
69 = 91ums
68 = 89ums
62 for 80ums
54 for 70ums

would be my guess

For the first Proof question. I did the n=1 step and I worked out what need to be added (2k+3/(k+1)^2(k+2)^2 but I couldnt simplify it to the actual answer. How many marks would that be?

Usually 1 mark for proving true for n=1, 1 mark for assuming n=k. Sometimes they give a mark for an attempt to prove, sometimes they only give 3rd mark for successful n=k+1 proof. Other 2 marks are available for successful proof for n=k+1 AND conclusion, you will (most definitely) not get conclusion marks without proving for n=k+1.

I'd say you probably have 2 or 3 marks out of 5.
