If `|[1,k,3],[3,k,-2],[2,3,-1]|`=0, then the value of k is

If [[1,2],[3,4]] [[3,1],[2,5]]=[[7,11],[k,23]], then write the value of k.

If the system of equations, x+2y-3z=1,(k+3)z=3,(2k+1)x+z=0 is inconsistent, then the value of k is (A) -3 (B) 1/2 (C) 0 (D) 2

If A= [{:(,1,0,2),(,0,2,1),(,2,0,3):}] is a root of polynomial x^(3)-6x^(2)+7x+k=0 then the value of k is

If A=[{:(0,2),(3,-4):}] and k A =[{:(0,3a),(2b,24):}], then find the value of b-a-k.

If the pair of linear equations (3k+1)x+3y-2 =0 and (k^2+1)x+(k-2)y-5=0 inconsistent, The value of k is

If int_0^1(3x^2+2x+k)dx=0, find the value of k

A random variable has the following distribution. {:(x=x_(i),,-3,,-2,,-1,,0,,1,,2),(P(x=x_(i)),,0.1,,2K,,3K,,7K,,0.2,,0.1):} Then for the values, A = K, B = Mean, C = Variance, the ascending order is

If k+3, 5k-1 and 3k+2 are in A.P., find the value of k.

Given (1-x^(3))^(n)=sum_(k=0)^(n)a_(k)x^(k)(1-x)^(3n-2k) then the value of 3*a_(k-1)+a_(k) is (a) "^(n)C_(k)*3^(k) (b) "^(n+1)C_(k)*3^(k) (c) "^(n+1)C_(k)*3^(k-1) (d) "^(n)C_(k-1)*3^(k)

(i) If the points (1,4),(3,-2)and (k,1) are collinear, fine the value of k. (ii) If the points A(k+1,2k),B(3k,2k+3)andC(5k-1,5k) are collinear, then find k
