We had to put down the numbers for frequency

Oh yeah that

 

[asadalam]

It was written 'f'

Well that isnt exactly labelling is it?We had to put in the values...

Have you guys started to prepare for P2 now?I've done half a paper then took a break....

2010 tak saray P2's done hain. Dont know what to do now. I guess 2011 kay karun aur phir IGCSE's kay thoray say karun ga.

Yup, no marks for that!

 

[asadalam]

Yup, no marks for that!

There are,we had to write the values

 

[Fate0]

?

Let X be the investment.

X + Interest = 2781
X + 3 x X x 1 / 100 = 2781
100X + 3X = 278100
103X = 278100
X = 2700

Of course everyone wrote the values. :S

Yup, no marks for that!

Srsly, how can u make a frequency polygon without having values on the y-axis

 

[asadalam]

Of course everyone wrote the values. :S

Just because everyone did it doesnt mean there arent marks for it.There are marks for each procedure and working.

Was it 180 euros and 500 dollars (that we had to convert - I am asking the question here - not teh answer)

VALUES or LABEL, there is Deviation of Earth and sky!

 

[sid2333]

Wht abt the timetable question and inequalities wht did u get as inequalities

wasn't the gradient o.5?

wht abt is equal to sign?
x=>1 same for y ?

 

[sid2333]

You just multiplied the whole second equation by 2. Is that ok?

the gradient was i guess, 0.5 and y-intercept was 2. so the eq was this : y=0.5x+2. so when multiplied by 2, it is: 2y= x+4 so the inequality was 2y<= x+4 I'm not quite sure it is correct. But I did the same!

 

[Kamihus]

A simple one for Chemistry. How did you know?
A Levels starts in September In Sh Allah, so yeah just this knowledge

An A-Level student here, so that's how I know.
Do those simple questions yourself, but don't always try to answer them, as they can be misleading 'sometimes'.

 

[exploded diper]

Which question?

the pics u said i were bout to post........dude the vertices one.....

wasnt y intercept 1
