Mathematics: Post your doubts here!

[kitkat <3 :P]

il see wat i can do. need two three days to prepare for it and my net is doomed.
lets see how lucky u ppl get
circular measure definitely
trignometry probably
functions if u get reaaly really lucky

Thank u

well i am going for medical so i don't think so

we know
P((1.9-b)<x<(1.9+b))=o.8 and mean=1.9 and SD=o.15
P((1.9-b-1.9)/0.15)<((1.9+b-1.9)/0.15) = o.8
ph of (b)/0.15)+ ph of (+b)/0.1 - 1= o.8
2ph of (b)/0.15=1.8
ph of (b)/0.15=0.9
from the normal distribution graph find the z value for o.9 p if you see the small ttable giveen below it would be easier z= 1.282

(b)/0.15=1.282
b=0.1923
limits 1.9-b and 1.9+b
that is 1.7077 and 2.0923
round of to 3 decimal places

THANKS FOR THE HELP

please try to solve this too http://papers.xtremepapers.com/CIE/...AS Level/Mathematics (9709)/9709_w05_qp_6.pdf

the

m not sure if i am right
but take an eg
when t=2
n=633

t=100
n=1800
so increasing, is it correct?

the answer is "the value of N approaches 1800" Thanks anyways for giving it a try.
