recheck ur 11th n 12th answers..
i think 11th is c n
12th is 30-u get quad eq w^2+15w-1350=0 -

1.C as !x!=-x if x<0
2.B 125*75=5^3*5^2*3=5^5*3 =>m=1,n=5
3.21 231=33*7=11*3*7 x+y+z=21
4.0.06 1-(p(a)+p(b)-p(a)*p(b))=.06
5.6 z=-1,=>x+y=4+1=5 x+y-z=5+1=6
6.D as for all x<=-4 A is greater
-4<=x<0 B is greater
7.D m+2k=3,an equation with 2 unkwns k can be any real value.
8.16 x+y=12,x+y+z=4z => 3z=12 => z=4,
perimetr=12+4=16
9.C the ratio proportion formula!!!
10.-60/7 x=0,15/7,-4,-3 ans:15/7*-4=-60/7
11.B 12=10+2
taking power 12 on both sides. 12^12=(10+2)^12>10^12+2^12
12.150 1350=45*30, l n b difr by 15, perimtr=2(75)=150 -

Napster, i tink some data is missing in the question.I remember same question which appeared in one of the previous databases where the question is given like : If x<0, then (-x)*(-x)/(-x) =

The answer of the question 4 can be derived like :
(1-0.8)*(1-0.7) = 0.06
what u ppl think? -

HI.
For the probability ques:
It can be done in two ways.
First:
1-[p(a)+p(b)-p(a)*p(b)] =
1- (0.8+0.7-0.56) = 1-0.94=0.06
Second:
You have rightly pointed
(1-0.8)(1-0.7) = 0.2*0.3 = 0.06 -

ans of 1st q: D
bcoz u cant determine wether x is +ve or -ve.... ans can be -x or +x -

ans of 1st is D
as u cnt say X is + or - if its positive thn its C otherwise its A
so duality in ans ....
thr4 ans is D
in 2nd one its 5^5 and 3^1 so obsly ans is B -

HI dude..plz check the 7th que, if the point lie on the line means, we can find slope (m)=2/1=2.
so substitute m values and (1,2) u will get k as 0 so ans is C.. -

In que 7 ans should be A.
As y intercept is 3 hence cordinate is (0,3)
and another pt on a line is (1,2),if we pass this line through this you will get slope -1 and k value 1. -

Shoot On Sight is an entertaining drama that addresses racism, politics, .. and terrorism.. It isn�t preachy � just fascinating.. But in the end it pays off as a good, old fashioned police thriller
