    Also, you know S1 interpolation? When you're finding the median when do you use the .5 value and when do you not

    Hai, I'm doing S1 on Friday and need some last minute help!

    It's edexcel June 2010 and I'm stuck on 3e, 4e and 6f.
    Any help greatly appreciated
    3(e)

    P(X \geq Y) \Rightarrow P(X \geq 6-2X)

    Can you solve it from here?


    4(e)

    If P(C | B) = P(C) , then they are statistically independent.


    6(f)

    d is measured in 100 km, while t is distance in km, so it can be said that:

    d = 100t

    In part (d), you found the equation of the regression line of the first fare rate (I'll call it f_1 here), in the form of f_1 = a+bd

    So the first fare rate f_1 in pounds sterling would be:

    a+bd = a+100bt

    The second fare rate f_2 in pounds sterling would be:

    f_2 = 0.05t

    So we have:

    f_1 = a + 100bt (using whatever a and b values you found)

    f_2 = 0.05t

    And you want the range of values for  f_1 > f_2

    Can you solve this inequality?

    If I have the two matrices M1 and M2 to represent the transformations T1 and T2, and I want to find the matrix representing the combined transformation of T2 then T1, do I do M1M2 or M2M1?

    Can someone tell me if I'm going insane on this question (6c) or if the book has it wrong? (CGP C4 AQA) (incl. working out, mark scheme, and graph)

    S1 edexcel

    the events A and B are independent
    Find P(A|B')
    In the mark scheme it says A and B' are independent so the answer is just P(A)
    Can someone explain why?

    The C1 paper is really bugging me, was a really decent paper and made some unbelievable stupid mistakes and only got around 60/75 maximum so most likely won't get an A for maths now

    Yes yes thank you so much!!!

    Provided you attain 240/300 you will still get an A, so 60/75 isn't the end of the world.
    If you do well on your applied module and C2 you should comfortably pass through the A boundary

    not as bad but I dropped 12 and pretty disappointed due to progress on past/solomon papers. np bro keep at it

    Ah have a good time, just try to get back into the swing of things soon

    Indeed it does, I didn't revise lifts or confusing suvat and they both came up bam in my face

    Yeah need to ace stats and C2, feeling confident about C2 but I think S1 will let me down. I am just hoping for a nice stats paper and hopefully I can get 70% minimum cause I like C2 the most so should hopefully get 90%+ thanks for replying

    I got a really nasty lifts question too bro!

    As I have already said, everything happens for a reason. And as my hero, J.K Rowling said"

    It is impossible to live without failing at something, unless you live so cautiously that you might has well not have lived at all, in which case you have failed by default."
