Solution: The determinant that results from removing the row and column that contain a given element is known as the minor of that element in a matrix.

Why the other choices are wrong

The formula A = (–1)i+j M, where M is a minor of aij, defines the cofactor of an element aij, represented by Aij.

c) The matrix’s modulus is not referred to as its determinant. Since a matrix is simply a collection of numbers, its modulus has no significance.

THE RIGHT ANSWER (A)

Answer:

There are six vowels.

There are nine non-vowels.

6! or 6P6 = 720 is the number of ways to arrange vowels.

9! or 9P9 is the number of ways to arrange non-vowels.

362880

There are two possible arrangements for vowels and non-vowels.

Two times two times two times two is the number of letter repetitions, as O, N, A, and

Each of them is repeating twice.

The sum of the ways is 6!x9!x2/2x2x2x2.

3.27 x 107

A is the right response. This is a test question.

permutation.

The right response is a

The given equation can be rewritten as follows:

2(x + y + 1) = 0.

Consequently, x + y + 1 = 0. Since the intersection of the x and y terms at zero is the center of a hyperbola, the center of this hyperbola is (-1, -1).

The response is (a) (-1,-1).

THE RIGHT ANSWER (B)

Tossing a single coin has a 1221 chance of producing no heads, or all tails. The likelihood of getting all tails when tossing five coins at once is as follows because each coin toss is independent:

P(all tails)=(1/2)^5=1/32

The likelihood of receiving at least one head, as determined by the complement rule, is now:

P(at least one head)=1−P(all tails)= 1−1/32 = 31/32

Therefore, when five unbiased coins are tossed at once, the odds of getting at least one head are 31/32.

A line is vertical if it is parallel to the y-axis, and its equation will have the form x = constant. This is due to the fact that the x-coordinate is constant for every point on the line.

Since the line is parallel, it is 3 units to the right of the y-axis, given that the distance from the y-axis is 3.Therefore, b) x = 3 is the right response.
