Check it out on the link Math_Angel gave you please and then let us know if you still have doubts. Do read throughly! :wink:

Re: Maths made easy =) stuck sumwhere?Ask ur doubts here!!
yes here we go
if the mean is 10 and there are six numbers then the total is 60
then the smallest number is more than 6 and the lagest is 16
the median is 9 and you have only six numbers so 9=the average of the third and fourth integer
so now arrange x x 8 10 x 16 then the qsn says that the mode is 8 so you have more than one 8 and it should be replaced by the first two x's
x 8 8 10 x 16 then it says that the first number is greater than 6 so it would be 7 or 8 so try the 7 and you'll have 7 8 8 10 11 16 or 8 8 8 10 10 16
hope this helped

Re: Maths made easy =) stuck sumwhere?Ask ur doubts here!!
Q2)(b) In the previous part you must have got this expression for the mean : 190/40
For the other n set of students, the total number of people will be 3n (mean = sum of all people in all families/no of families)
So the expression will be (190 + 3n)/(40 + n).
Q3) (d) For a 90* clockwise rotation about the origin, the transformation matrix is always (0 1)
(-1 0)
Q7) (c)(iii)The perimeter consists of three straight lines and three arcs. Each arc is the same as arc DE (found in previous part to be 0.6492625 m).
Each straight line actually is made of 6 radii of the circles. So perimeter = 3(0.6492625) + 6(3)(0.31) = 7.53 m (correct to 3 sig. fig.)
(iv) simply multiply the perimeter with the length = 7. 5277875 x 15 = 113 m^2 (correct to 3 sig. fig.)
Q11) (d) (i) Just consider the first diagram. n = 1 and the number of lines is 6.
=> k (1^2 + 1 + 1) = 6
=> 3k = 6
so k = 2
(ii) Insert 100 into the formula.
2 (100^2 + 100 + 1 ) = 2 (10 000 + 100 + 1 ) = 2 x 10, 101 = 20, 202.
Hope this cleared your confusion!

Re: Maths made easy =) stuck sumwhere?Ask ur doubts here!!
Q1(b) (i) Interest = Amount - principal = 99 - 90 = $9.
Using the formula, I = PRT /100
=> 9 = (90 x r x 2)/100
=> r = 5.
Q2) (b) (ii) OM = OC + CM
Q3) (d) Probabilty that the spinner stops on 2 = 2/6 = 1/3
probability that it does not stop on 2 is = 4/6 = 2/3
(2/3)^(n-1) x 1/3 = 16/243 = 2^4/3^5.
Now you do the simple arithmetic! Hope this helped a lot!

Shearing is parallel to the invariant line. The image was to the right of the original. So inv. line was x-axis.henry407 said:

Re: Maths made easy =) stuck sumwhere?Ask ur doubts here!!
Well its quite simple !!
As the triangle inside the circle is equilateral, all 3 sides are 60 degrees
so the angles of the half triangle is 30 degrees
Therefore : 90-30=60 degrees
so both sides are 60*
umm well dats how it is I guess !!
Correct me if I am wrong

AoA!
Can you kindly look at Q22(c) of this paper: http://www.xtremepapers.me/CIE/Cambridg ... 4_qp_2.pdf
It's a one mark question but please tell me how you figure it out.
JazakAllah!
and also
Can you kindly help me with question 9 part (f) of this paper: http://www.xtremepapers.me/CIE/Cambridg ... 4_qp_4.pdf
Here's the mark scheme: http://www.xtremepapers.me/CIE/Cambridg ... s04_ms.pdf
Your help will be very much appreciated. Thank you!
