How many matrices of the order 3×3 can be formed by using the elements either A or B is?

So, the correct answer is “512”.

What is the total number of 3 3 matrices whose elements belong to the set {- 1 1 having its determinant equal to 0?

#({−1,1} matrices with zero determinant)=29−8×6×4=320. (Answer)

How do you call a matrix whose entries are all nonnegative and all the column sums equals one?

stochastic matrix
In a stochastic matrix, all entries are nonnegative, and each column sums to 1. The product of stochastic matrices is stochastic.

How many matrices of 3×3 can be written with each entry either 0 or 1?

A matrix of order 3 x 3 has 9 elements. Now each element can be 0 or 1. =512 , ∴ (D) is correct answer.

How do you find the number of possible matrices of order 3×3?

The given matrix of the order 3×3 ha 9 elements and each of these elements can be either 0 or 1. Now, each of the 9 elements can be chosen in two possible ways. Therefore, by the multiplication principle, the required number of possible matrices is 29=512.

How many 3 3 matrices M with entries from 0 1 2 are there for which the sum of the diagonal entries of Mt M is 5?

Hence, the total number of combinations ( i.e. total number of matrices with entries from {0, 1 and 2} for which the sum of diagonal entries of \[{{M}^{T}}M\]is 5) is 126+72 = 198.

What is the number of all possible 2/3 matrices with entries 0 or 1?

In this question, we are given a matrix of order 2 $\times $ 3. Using formula (1), we can say that the number of elements in this matrix is equal to (2)(3) = 6. Also, in the question, it is given that at every place, the matrix can have either 0 or 1.

What is a matrix of 1 and 0 called?

A -matrix is an integer matrix in which each element is a 0 or 1. It is also called a logical matrix, binary matrix, relation matrix, or Boolean matrix. The number of binary matrices is , so the number of square binary matrices is which, for.

What are math matrices?

matrix, a set of numbers arranged in rows and columns so as to form a rectangular array. The numbers are called the elements, or entries, of the matrix. Matrices have wide applications in engineering, physics, economics, and statistics as well as in various branches of mathematics.
