It depends....sometimes it givn sometimes its not.....so better learn as a precautioni think vol. of sphere and cone formula would be given.
You know some formulas are derivable if you know the basic ones.yeah i guess ur right , i'll just revise all of them
wow!.... who told u the question is about plotting points? if it was that simple than i wouldnt be asking... anyways its okay i know the answer of that question.... but im still in doubt of question 8b and 8cHow can someone explain hw to plot points???
what do u wanna kno bout probability pls send ur doubts to [email protected]Hey will u please help me in Probability and vectors
my exams are tomorrow
and i dont know anything about that
Divide 18(the frequency shown in table) by 7(the no.of square boxes is 3.5*2)How do we do question 8c (iii) in paper 4 October 2009? Help please.
2.5 studentsDivide 18(the frequency shown in table) by 7(the no.of square boxes is 3.5*2)
Yup....as the mark scheme says!!!!!2.5 students
hmmm totally rite!!!Yup....as the mark scheme says!!!!!
who knows?Salaam.
Hey.
That's a tough question. Is that an IGCSE question?
I got this answer.
kq-q=q
q(k-1)=q
k-1 = q/q
k-1 = 1
k = 1+1
k = 2
How did you get 3.5 and why did you multiply it by 2? :SDivide 18(the frequency shown in table) by 7(the no.of square boxes is 3.5*2)
Count half part of each block as one.How didnu get 3.5 and why did you multiply it by 2? :S
see 1 cm2 is 5 squares
frequency 18 is 36 squares
hw much frequency is 5 squares?
Ans- (5*18)/36= 2.5
1 cm on y axis is 5 squaresHow did you know 1 cm2 is 5 squares though ?
to find the inverse of that function you have to use one of the laws of logsanswer is x√3
ps : that is "x root 3"
