54.
5 I think. Right?
y=<0.5x+1
x>=1

The aswer to estimation was 4 (40/10)

Well,how much do u expect in P1..
.wht abt tht question of polygon shud we have indicated htt whether this is boys and htt is girls polygon or anything?..I don't think we had to?

75-77 inshaallah what about you?We didnt but i did label both of them

7 probably.

1 mark gone in that order (wrote 6). Got the BODMAS wrong, got that bus wrong, 2 marks deducted on that simplification and 1 mark gone in that n-polygon (wrote 20 instead of 24). Most of the other is correct but there is always the odd 1-2 mark mistakes ka chance (maybe that I only connected midpoints in that freq polygon question)

We have to use midpoints of class width and join them,where do you think you are wrong?

What? Was it 10 x 1 ? Wasn't it 10 x 0.8?

It was 5 40/8=5

 

[asadalam]

What? Was it 10 x 1 ? Wasn't it 10 x 0.8?

It was 5,and yes 0.8 was involved i think.We had to use 0.8 instead of 1,since 0.8 is also correct to 1 sig fig

 

[muhammadali233]

it was 5

bhai 1 sig fig parha hai?

 

[Abdul Hanan]

median was -2.5 guys?

 

[asadalam]

Midpoints hi na? Nothing else. Just connect them. Nothing on axis (origin/end)?

No i read in the ms that they ignore it s08ms and it was only of 3 marks, 2 for each polygons and 1 for correct plotting and joining,so dont worry.

 

[Abdul Hanan]

bhai 1 sig fig parha hai?

ji bhai 0.8 is 1 sig figure..
final answer was 5

 

[asadalam]

0.878whatever to ONE significant figure is 1

Firstly it was 0.787 something and 0.8 is correct to 1 sig fig

 

[asadalam]

median was -2.5 guys?

Yes.

Don't join on axis in Er they forbid u so it,s much better not to.In previous MS they stated tht further diagrams will be ignored though I doubt tht wht they said in ER they might penalize for extras

They IGNORE so no penalisation no nothing it doesnt matter at all.

Dayummmm

 

[M.Omar]

max temp diff and also wht was v in v/t graph

 

[asadalam]

Any other questions?

 

[asadalam]

max temp diff and also wht was v in v/t graph

v was 10 and max temp diff was 9.Speed in kmph was 108 but i screwed up and wrote 54 :/ expression was v/25

 

[M.Omar]

They IGNORE so no penalisation no nothing it doesnt matter at all.

Like I said frm ER .............
They wud ignore in this case but it wud be much better not commit such things at all..Just get the body right and there is nothing to worry abt

 

[Abdul Hanan]

guys i joined the polygons to axis...... is there any problem?
e.g i started boys from origin and extended ends of both to end corner
