calculate the mean and standard deviation of a set of data (including
grouped data) either from the data itself or from given totals such as
Σx and Σx2
, or Σ(x – a) and Σ(x – a)
For P1 maths Nov 2013,we had the the last question to find values of k for which fg(x) have equal roots for K, i was in a hurry and instead of doing fg(x) i equated f and g.(as in put F(x)=G(x)). that was such an easy question carrying FOUR MARKS and i messed up. But i did mention, for equal roots, b^2- 4ac=0 and solved it. Can i get some marks? Maybe even 1 mark?
Can you please help me??
June 2003 paper 3 question 9 (ii). I can't obtain the answer in the mark scheme. I've done it in cartesian form and i've got (12-6t/7 1+10t/7 t). But when i am replacing parameter, i can't seem to get the same answer as in the ms!
please help. thank you.
