the last answer is wrong.
and the answer for sphere is wrong too.
Thanks, what about the one with vase volume?
guys, if I made the cumulative frequency graph looking like a bar chart, will i get marks for interquartile range and the graph itself?

Also there was one which was to rearrange to find t....
I have forgotten though
And sorry for disturbance again, does anyone remember about how many marks was the vase question and the graph question?

I thought they were - and have previously posted mathematical evidence supporting these answers. But if you have mathematical evidence to the contrary, go for it :biggrin:

Vase was 3 marks.
The graph itself was probably 3 or 4 marks, and the IQ range and measurement of number of people over 85 kg were probably 2 marks each. If you did a bar chart you will most likely lose 4 or 5 out of the seven available.

Yeah, I posted the question, working and answer for that a bit further up.

I believe that they are not and have previously posted mathematical evidence supporting these answers. If you wish to prove me wrong, go ahead, but please show some mathematical evidence.


i am not sure about the sphere question, but i am pretty sure about the pentagon question.
the pentagon was to be divided in a triangle and trapezium. and then we can find out the area.

Here is my working supporting the 188 answer.

. was there marks for ploting the graph because i did it in line segmet not smoth curve but i still got the range 20 and the 85 g 18 will i get full mark ? ?

By line segment do you mean "join the dots"? If so, then that is correct - they accept smooth curve and join the dots. I got 20 as the IQ range and 18 too, so i believe you will get full marks for that question.

yes i joint the point with ruler way not straight line X..

how many marks was that q ?
