Few questions from CBSE Class 12 Maths Sample Paper 2019 are given below:
Find the order of matrix (5A - 2B) if A and B are two matrices of the order 3 × m and 3 × n, respectively and m = n,
We are given that, the order of the matrices A and B are 3 × m and 3 × n respectively. Now, If m = n, then A and B have same orders as 3 × n each, so the order of (5A – 2B) should be same.
Find the differential equation of system of concentric circles with centre (1, 2).
The family of concentric circle with centre (1, 2) and radius a is given by
(x -1)2 + (y - 2)2 = a2
⇒ x2 + 1 - 2x + y2 + 4 - 4y = a2
⇒ x2 + y2 - 2x - 4y + 5 = a2 …(i)
On differentiating Eq. (i) w.r.t. x, we get
An urn contains 5 red and 2 black balls. Two balls are randomly drawn. Let X represents the number of black balls. What are the possible values of X? Is X a random variable?
B = black ball
R = red ball
Sample space of two balls selected = BB, BR, RB, RR
X = number of black balls
X (BB) = 2
X (BR) = 1
X (RB) = 1
X (RR) = 0
Hence, the possible values of X = 0, 1, and 2. We can say that X is a random variable.
Find the equation of the plane through the intersection of the planes 3x – y + 2z – 4 = 0 and x + y + z − 2 = 0 and the point (2, 2, 1).
Equations of planes are:
3x − y + 2z - 4 = 0 and x + y + z − 2 = 0
The equation of plane through the intersection of the above planes is:
