And please tell me one more think confirmed that if the examiners mark if the previous part is wrong but in second part formula and everything is right but answer is wrong due to first part?
like for eg. In the cone and circular base question where we had to find l... if our l is wrong but the next part in which they asked curved surface area , if our Woking using l is correct but final answer wrong due to l then will the examiners give mark?

Probability first one was 19/28. Second one asked that she then picks a third sweet, calculate the probability that she does not pick lemon in any of the 3 times. I did O,O,S and S,O,O and O,S,O and got 3/28. I didn't use cos anywhere except first question of trigonometry, the 4 mark one, calculating the length thingy..

Was probability of picking a lemon 5/8?
Because then i did 1-5/8 which is 3/8 for not getting lemon. Then 3/8 * 3/7 * 3/6

Yes probably since it's equal to 3:4

WHATT I WROTE 3:1

Yes, i think they use ft or ecf in math, although maybe mark for the answer will be wrong but method will gain

:""""""( Guys pleaseee let me know the grades threshold as soon as they are out

 

[masterex567]

Nope there were 3 Lemon, so probability of not picking lemon was 5/8. But that's wrong too I guess, because they said she "THEN" picked 3rd one which means first 2 times she picked different colors only. So we had to do combinations OSO SOO and OOS.

Oh yes then i did 5/8 * 4/7 * 3/6.
This is correct i think, because when not picking lemon is 5/8 it accounts for probabilities of other qualities.

feb bro

 

[chum1234]

i got 3:4!
im sure it's correct

But did u try using the ratio to work out AN coz when u use 3:4 u do not get the correct vector :S

 

[NOneed2speedd]

And in that light house closest distance. ... did we had to calculate x or y?

 

[masterex567]

But did u try using the ratio to work out AN coz when u use 3:4 u do not get the correct vector :S

it was AL : AN and work out the vectors then divide by them you get 3/4 : 1
which multiply by 4 both sides

 

[chum1234]

it was AL : AN and work out the vectors then divide by them you get 3/4 : 1
which multiply by 4 both sides

Oh ok thanks IM FAILING

Did u like get everything right !!!??!?!?! please say no .. I HOPE THIS TIME A* RANGE IS REALLY LOW

 

[maxwell391]

bloody ***k ppr it was

 

[masterex567]

Hahahah i probably failed bearing, ratio and the histogram explanations. The rest was good enough
Curve will surely lower compared to last year.

 

[maxwell391]

me is gonna fail......fr sure no doubts

 

[chum1234]

me is gonna fail......fr sure no doubts

Hehehe with you bro D: I Dont understand how people managed to do it ... im damn sure losing 26 marks and many more

 

[Abdurrahmanmuhammed]

what was that fuel question? 600/x question
what were the answers?

easy shit

Omg hi-5 i usually love ratio !! but this time it was yuck ... really i found the histogram the only easy question

 

[maxwell391]

noooo..

Are this year's thresholds out yet?

 

[Abdurrahmanmuhammed]

M

Ans was 7.5..... 600/80

they asked complete journey yeah ?
so both the 600/80 you need to consider the 600/80+20 also
