Hey, I dont really get the 3. step of the inverse calculations. Which numbers do you have to muliply and how to you get the results not connected to you "arrows"?
actually the 15 should swap with the -2 and then it would be correct
you first multiply the first and second column where 1*4 is the positive diagonal and 2*0 the negative one, then you add them up and this forms the 4 in the first entry
where do u find pe ?

You made a mistake calculating the SE(μ), its actually 21,7 so the answer is c
Yep, you're right. I did correct that already though in the document. Thanks anyways.

Hi Nomad! Just had a look and downloaded your documents (good stuff!), would appreciate if you could have a look and download mine too :)
This become [478.13;549.98} Which makes it answer C
I made an error calculating the terms. The answer is 21.66 of course.
of exercise 3 after the first r3 minus r2 in the RHS I
You simply subtract 1 (r2) from 2 (r3) and you get 1
where did you get the 1 in position 3,3

Is exercise 7 reasoning correct?
can you do that? Aren't we supposed to do an operation on 1 (here you do an operation on 2)
with 2 and 3 it is not, it is problematic. for the sake of the exercise, ignore
((50-55.022)^2 / 55.022) + ((57-45.628)^2/ 45.628)+ ((15-21.35)^2/21.35) = 5.181
p2 = 0.374. p3 = 0.175
p1= 0.451

Could you explain what youve done for q8
Each operation in green next to the row in question changes that row and is added or subtracted or multiplied or divided (whatever the sign is) to the row that the green arrow leads to

12) b) Should be v3 = M^2 * v1 ?
I got the same answer
Here you are obtaining a column. Ex 10(a) asks for the 1st row resulting from AB
Noticed that in the tut today haha my mistake
Isnt F correct? After brackets E times AC results, obtaning 5,4 * 4,2 Your case the result is AC*E not same as E*AC
Yes you are correct, thank you for pointing it out :)
I find 7.223 using the same calculation as in the answer sheet. Can someone explain why the correct answer is C ?
Any complaints?
Can anyone provide a full explanation/calculation? I seem to make a mistake at taking the derivative of each lagrange. I get for derivate of g: p^2 - 50/sqr root g * lambda and the answer say something different but basically the same....
On the success formula slides for Maths, Page 23. How did the last row become 0 10 12
i get we used gaussian elimination but why?
