Maths, Addmaths and Statistics: Post your doubts here!

Technically, that question was stupid. Or either i'm stupid.
I mean, why give such a figure? They've always given an even number. But this time they gave 33.

So the answer was 40.5.. And they asked us to ESTIMATE? Now on what grounds should we estimate? Mathematically? Realistically? Biologically, assuming that 0.5 can't be a person?

People say it should be either 40 or 41. Okay, i get it now. It should be a whole number.

But I wrote 40.5/40 in the working space. That proves i understood the concept of rounding it, as number of children can not be 0.5.

But again. is this biology or is this maths? This isn't the science of nature; Biology. This is maths.
Number of children can't be 0.5 in biology, okay. But they can be in maths. Maths is about numbers. It's about calculations.
So if i give an ESTIMATE, which is exact.. (As compared to those people who give 40/41 and just rule out the 0.5 part, and just ignore it.. i'm giving a more accurate answer)..

But even though 40.5 is wrong, i still wrote ''40.5/40'' in the working space.. But wrote ''40.5'' on the answer line!

Well,going towards the height question wht did u get for height of cone and the mass..U did draw a frequency density axis right?
And also what did u write in proving tht two lines are paralle in circles question?

Correct.

Shukar ha....

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. :/

But which question?

622 or 664/662 or like tht

 

[asadalam]

Well overall the paper was easy,surprisingly no transformation.I left the graph q.I was also relieved to find that my last 2 parts in mensuration are right,i first wrote them wrong and rechecked and corrected them,by only silly mistake i think was that in the locus q i made D on the right side instead of left.But that would be at most of 2 marks,so am hoping for an A* in maths in sha allah

622 or 664/662 or like tht

Yes.. And.. other questions?

What was the answer to nth term Question.Last part that was of [4] marks
My answer was n= 24 , 3
I think i'll get 2/4 marks bcz 24 is correct and i'm not sure about 3
What was the answer actually???

Wasn't it supposed to be made on the right side???

I meant the paralle lines wala part...Btw they were not equilateral triangles at leats we cud not prove them...
Again am talking abt tht question in which two lines for our answer was given

 

[asadalam]

622 or 664/662 or like tht

It was like 665 i think or 66 somethin(there was definitely 66 in first 2 digits.

Both are correct

So u r free.
Hakuna Matata!

Pata nai,some of my friends were saying that it was on left side....of AB... i dont remember exactly.And the bearing in last part was 120 right.

Yes, their were equilateral. Their were two triangles being formed, each with 3 radii.. which were equal..

Was D on right or left of AB?And the bearing in last part was 120?

NO, 249.
