Answer:
2
Step-by-step explanation:
Answer:
Option C
Step-by-step explanation:
- For the matrix A of order
to be invertible, its determinant must not be equal to zero, |A|
0,
exists if- AC = CA = I, where I is identity matrix.
- The homogeneous equation with coefficient matrix A has a unique solution:
AB = 0, B = 
Thus, B = (0, 0, 0......., 0) is a unique solution
2. The non - homogeneous equation system with coefficient matrix A has a unique solution:
For an equation- AY = D
Y =
is a unique solution
3. Every non homogeneous equation with coefficient matrix A is not consistent as:
For an equation- AY = D, has a solution.l Thus coefficient matrix is inconsistent whereas augmented matrix is.
4. Rank of matrix A = n, Thus the column space of A is 
5. Since, column space of A =
, thus x→xA is one-to-one
Answer: P(5A) = 0
Step-by-step explanation:
There are four aces in total in a 52 card deck. Therefore the probability of getting 5 aces can be expressed as;
P(5A) = 4/52 × 3/51 × 2/50 × 1/49 × 0/48 = 0
Therefore, it is impossible to get 5 aces from a standard 52 cards deck
2 feet to 3 yards
i divided both sides by 7
