i messed up the probability q tho :frown:

what about the bihra guy the propotion i got 51.6 will they give me full mark ?

Did you get (in cumulative frequency)
18 for over 85kg and 18 for interquartile range?

Which graph question? Not the line equation prediction? Are you talking about the interquartile range?

yes the interqul one what did you get for part a n b

and the first graph did you make it straight line ?

If I do really well on paper2 will it help? as I've got none of these answers

i think i got 20 for first one and 18 for second one and i did the graph in segmat line is it ok ?

What was the equation prediction for the line L? I got the gradient as 3/4 but couldn't do the rest of the question. :s-smilie:

I found that paper good until like question 13 onward. lmao.

Straight line for first graph (curve for weight graph), i think i got 16.5 for interquartile range or something like that. Don't remember the other answer

yes i got the same m then i used this formula (y-9)=m(x-6) i used these coordinates
is tha right ???? @iah1700 did you do the same ?

for that gradient one i got 3/4x-4.75 or something like that but it wanted it in ax+by=c so i just made it -3/4x +1y=-4.75... it wanted a b and c as integers as well

As it wanted it in integers, you just had to times it by four
-3x+4y=19

For the line question i got:3x - 4y = 19

For the cube/sphere one, I think I got something like 1637

I can't remember the probability one fully, but it was something over 80 something :biggrin:

I got 188 for the area of the pentaagon

and make T the subject did you get T= m+1/3m-1?
