No he made a site olevel.sourceforge and uploaded them there.

the height wasn't 18.9 as we didn'

The height was 18.9. Surface area was 622..

And i wrote that their are equilateral triangles, and there were 60 degrees alternate angles, so that only happens in parallel lines. Others wrote about their being a rectangle. :/

t need to take cube as diameter was same...

 

[Dark Destination]

Right par bhi to hosakta hai

They said WEST. And had a North sign on top.

Ohkay.

 

[Dark Destination]

PQ Vector ka magnitude kya tha?

6.40

 

[Dark Destination]

Wasn't it 4, -5? ._.

P(4,2) Q(8,-3)

Calculate yourself.

 

[Dark Destination]

R was 12, -8 right?

Yes.

Nabeel's memory is the bomb. You would probably be the World's No.1 witness.

Two days ago, at 23 hours, 52 minutes and 28 seconds, I first laid sight at the robbery.

Hahah.

Are you guys sure kay frequency density ka graph banna tha because they didnt mention it.
Most of my friends and I made for frequency.
And for the one saying, histogram is only made by frequency density, no sir. You can make a histogram of frequencies aswell.

Well the ER in MJ 2013 P21 says tht few candidates made the correct version by taking frequency density......

There were unequal intervals i,e class widths.Thus we had to make f.d.And by most i assume you mean some,because 'most' people would normally make by f.d without thinking twice,like me and others.From the er:
Very few candidates knew that they had to use the frequency densities when drawing this
histogram because of the different class widths. The majority who attempted this part drew a
histogram just using the frequencies
