EXERCISE 13. 5 Q.NO. 1, 2 AND 3

Set Q ={10, 2, 3, 5, 1, 7, 5, 2} If smallest and largest numbers in Set Q are removed, what is the median of Set Q?

If variance of 1, 3, 5, 7, …….. 215 is A^(2) then standard deviation of 1, 5, 9, 13, …..429 in terms of A is :

if (1+3+5+7+....(2p-1))+(1+3+5+...+(2q-1)) =1+3+5+...+(2r -1), then least possible value of p+q+r (Given p>5 ) is:

if (1+3+5+7+....(2p-1))+(1+3+5+...+(2q-1)) = 1+3+5+...+(2r -1), then least possible value of p+q+r (Given p>5 ) is:

The adjoint of the matrix [(2,5),(3,1)] is (A) [(2,5),(3,1)] (B) [(1,-5),(-3,2)] (C) [(1,-3),(-5,2)] (D) [(-1,3),(5,-2)]

If [(2+x,3,4),(1,-1,2),(x,1,-5)] is a singular matrix then x is (A) 13/25 (B) -25/13 (C) 5/13 (D) 25/13

Exercise 2. Let R (1, 3), (2, 5), (3, 7), (4, 9), (5, 11) be a relation in the set A ={1, 2, 3, 4 ,5 }Find the domain and range of R

The point on the line 3x-2y=1 which is closest to the origin is (A) (3/13, - 2/13) (B) (5/11, 2/11) (C) (3/5, 2/5) (D) none of these

Find the Q_(1)andQ_(3) for the following distribution : 5, 3, 6, 3, 13, 9, 8, 24, 19, 20, 18.

Let X = {1, 2, 3,.......... 10} and P = {1, 2, 3, 4, 5} . The number of subsets Q of X such that P Delta Q = {3) is __________
