Maths, Addmaths and Statistics: Post your doubts here!

[ashiqbal]

Can we use fx-911ES for add maths...I'm used to it I heard people say u cant

actually they dont usually check for the calculator models and pupils have been known to take these calculators. The invigilators at most just erase your programming if it is a programmable calculator.

After all, more than 50% of the pupils have the most recent calculator. They cant take away everyone's calculator, can they?

you remind me of my english teacher..he always says
English is for Life...then why are we studying it.......BANANA DANCE!!

LOL YEAH also if u look at M/J 11 er of some paper 1 there u will see CIE say themselves that with technology increasing and ............... therefore candidates should show more working to get the marks so indirectly they themselves allow it

exactly! they now give method marks also, and usually only 1 or 2 marks are for correct answer at end!

umm i guess that a good thing...

umm
4 x 4!..
cuz you have 4 numbers to start with and it could be either of them
could not understand the 2nd part myself...
will look to it tomorrow!!

for b, look into it this way:
if for first number we take 4 or 2, the last number could be any one of only 2 of either , 0,2,4(one of these is already used in the beginning). the numbers in middle will be arranged as 3!(factorial). so your first possibility becomes : 2C1 * 3! * 2C1
If we take first number 3 or 1, the last number could be any one of either , 0,2,4. the numbers in middle will be arranged as 3!(factorial). so your first possibility becomes : 2C1 * 3! * 3C1

add these two to get the answer
the answer will be 60!

8 (b)(iii), (c)(ii)
with method pls..

8 (b)(iii), (c)(ii)
with method pls..

my guesss
8 b(iii)
would be the 20th term as you can see from the other terms which they have given so its pretty simple try solving it and then letme know and then il solve it

c (ii) let me think..

You will have to take the long route in place of n in the general equation write the term given and u will see its equal so show that its quite tiresome ill tell u that

Part 8b(iii) simply equate 20 to the nth term of the sequence. the one given on the above part .and the answer will be 1540 !
