Paper 1. Question 10. You mean that u can't help bcz u don't know?

 

[scarificeurlaav]

either you linked the wrong paper, or you seriously need to open the maths book

Time and Limits of Accuracy will be the chapters.

for the time question you have to multiply that number by sixty.

for the other.. you have to first find the upper bound .. which is 1.55kg then multiply it with 1000 to get the answer.

I still don't get the time question

I don't know whether i can help or not .. but that diagram is the reason why I am not able to .. and the weird thing is .. in June 1998 Paper 1 Question 0 .. its a Pie chart involving statistics .. lol you got the paper and question right?

 

[syed1995]

I still don't get the time question

there are 60 minutes in an hour.

2.15 hours would mean 2.15 hours ..

2.15*60=129 minutes ..

2*60=120 ..

so 2 hours 9 minutes will be the answer.

you gotta be kidding me .. apply BODMAS (Brackets Open Division Multiply Add Subtract)
Apply that to it .. starting from the left side.

 

[Talhakhan]

First i multiply then add and then subtract right....

Yes

 

[Talhakhan]

Yes

By this i get answer = 1 but in markig scheme it is 3 why???

=17 − 5 × 3 + 1
=17 - 15 + 1
=2 + 1
=3

Need Help in Question 9 a(ii) http://www.xtremepapers.com/papers/CIE/Cambridge International O Level/Mathematics D (Calculator Version) (4024)/4024_s11_qp_21.pdf

and should the areas of rectangles in the historgram equal?

But first you said add first than subtract ...... Keep your word man!!!!

WE HAVE TO FIRST MULTIPLY ... alright?

it becomes

17 -15 +1

-15 +1 IS NOT 16 dude .. its -14 ..

17 - 14 = 3.

LoL dude....this is Add. Maths, not simple maths!

No....you'll have to calculate frequency density.
