How was your Mathematics syllabus D paper 1?

[Fallen316]

it was g(a-2) nd the ans to that i got was quiet wierd cz it was x^2+7x-11

wasn't it a^2+7a-11 ?
we had to give the answer in a terms , right ?

well, im not sure. That's jsut my answer. I could be wrong xD

i believe 8/15 is the correct answer.

that's what i got.

Yar girl n boy ki probability thi Girl both CLass A n B = 1/3 n for boys both class it was 2/3 ! Theny Said one boy n one girl !

8/15 aarahi thi ..

Kitney marks ka tha woh sawal ?

hey.. what about the circle in a square? They have asked to put in form of a and b pie. What is the answer for that question?

 

[syed1995]

2/5 3/5 2/3 1/3

Total - Boy/Boy + Girl/Girl
1- (2/5*2/3 + 3/5*1/3)

(4/15 + 3/15)

1- (7/15)

1-7/15
=8/15 Answer.

64-9Pi ?

 

[syed1995]

Kitney marks ka tha woh sawal ?

2 i think

 

[Shehan Livera]

64-10Pi ?

what was the radius of the circle?

 

[Rimi]

64-10Pi ?

it was 64- 9pi :3

 

[syed1995]

it was 64- 9pi :3

yeah that's right ... 8^2 - 3^2Pi

 

[Shehan Livera]

it was 64- 9pi :3

Thats what i got 64-9pi

yes ryt. in terms of a. but i wrote in x!!! wat do u think...how many marks may b deducted?

not sure, maybe 1 .

 

[pakiboy]

oh shoot. I messed up that question. I didn't even take the midpont values -.- I'll lose some good 3 marks there.

me 2 didnt take mdpoint values how much marks will it cost me........

 

[haha101]

2 i think

N wht about the whole probability Q ? tree kitney marks ka tha ?

The one in which we had to make a Frequency Polygon :
I made a histogram and then joined the mid-values of each bar to make the polygon ( this is the only way to draw a frequency polygon) , but i wanted to ask that do we have to erase the histogram afterwards or let it be .

The question had two marks , i think 1 was for the histogram and 1 was for the polygon . So we had to show both .
Anyone agree?

@ Fallen316 meinay agar freq. polygon mein midpoints nae liye tou meray ktne marks kateingax any idea................
