Challenging math questions paper 42

[Dooouuu]

guys, do you think there will be a range of answers for probability since values quoted from the graph may vary???

yeah i hope so

 

[Ramosk95]

ok then you had a different qsn although i set for paper 42 i dont know but remember well what was ur varient
in 42 the sequences were about dots that forms triangles

yes indeed 42 ... btw it was about lines not dots

 

[Ramosk95]

ok same i mean it consists of dots but your telling me that in the first sequence there was 12 lines but the qsn states that they were 9 :%)

 

[Dooouuu]

the first diagram is 3 and the second is 9 .. the question was for THE TOTAL OF THE FIRST N DIAGRAMS

 

[Ramosk95]

the total number of one cm line not the total of diagrams

 

[Dooouuu]

the total number of one cm line not the total of diagrams

yeah yeah i mean thatt

SEQUNCE QUESTION WAS : a=-0.25 and b=2.25
I have also substitued my values with n=3, and my answer was correct (same as what they drew)!

 

[Adahshan]

Kokeeto, Yes but your still wrong. If you start wrong, you will end wrong but when checking the equation it will show right.

It was 0.5 and 1.5, I had couple of teachers show me how to do it after the exam, it is 0.5 and 1.5 ;/

 

[Kokeeto]

Wait, what variant are you talking about?

 

[molluscs]

It's funny how you ask what variant we're talkig about when the topic subject clearly states paper 42
LCM(lowest common MULTIPLE)- 240
HCF(highest common FACTOR)- 12

That answer's correct.

I wrote -0.25 and 2.25 and I know its wrong but I would still get 4 or 5 marks out of 6 for sure as I havent read the question properly only
