2. 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)

Can you solve it from here?

4(e)

If , 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:

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

So the first fare rate in pounds sterling would be:

The second fare rate in pounds sterling would be:

So we have:

(using whatever a and b values you found)

And you want the range of values for

Can you solve this inequality?
6. 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?

7. 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)

8. 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?

You'll be fine then!
Yeah on Friday
are you doing the ocr mei board? can you help me with question 6 may 2005 C2
12. 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

Don't worry man I felt like that at first, I only just got back to revising today, I need to anyway got S1 coming up, M1 will be my lowest module I suppose but hopefully we can drag our scores up with other modules bro!.

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

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."
