L was 75, it was to be found using similar shape method. What was the answer for the ratio of the vectors? 3:4 or 3:1?

3:4

What do you guys think will be the threshold for this paper for A or A*??

i dont know but was it like dis

15/8=35/x
so x=8*35/15= ans+35 right??

3:4

aagaya pundit!!

What about the k value in the graph? And the a,b,c values in the following question?

 

[Saad the Paki]

value of l, the slant height?
and value of k for the graph... and den value of a,b and c?
Last page probability?
1st question total number in the club?

3:4

i did 1:0.5 :'( :'(

Nope, it was L/L-35 = 15 / 8, solve it to give L as 75.

 

[Saad the Paki]

My value for l was 75.2

 

[Saad the Paki]

I used sine rule

I feel so dumb now...

Probability first part was 19/28 and second part was 3/28 I think.

slant height i got around 54
value of k i got=a=-5 b=-1 c=12 i am nt sure of the values
probabilty last one was find all three LLL=3/8*2/7*1/6=55/56
total number i got 124!! i dont know!!

why what happened punditji?

heyy first part is right!! second part is 55/56

probabilty last one was find all three LLL=3/8*2/7*1/6=55/56
total number i got 124!! i dont know!!

the values for a b and c were supposed to be found by drawing a line... but the answer was very weird

heyy first part is right!! second part is 55/56

nope.. u r wrong on this one

 

[AnonymousX9]

How is it 55/56? They said she then picked a third sweet, find probability that she does not pick Lemon in any of the three so it could be either O,S,O or S,O,O or O,O,S. That gives 3/28.

Yup thats ryt

 

[iThink LARGE]

My value for l was 75.2

yeah i got 75.2 too
is that right?

 

[Saad the Paki]

yeah i got 75.2 too
is that right?

I think so... u used similarity or what?
