Which of the following is a consequence of increasing variability?​ Group of answer choices ​A.The distance from one score to an
Irina-Kira [14]

Answer:

Step-by-step explanation:

The distance from one score to another tends to increase, and a single score tends to provide a less accurate representation of the entire distribution.

Consider normal distribution it has increasing trend from -Inf to the mean. But has no probability at any point. But if you consider binomial distribution then you will get the information at any integer of its range, but not all values of real line. That is you will not have information on (0,1) so there you cannot comment for increment of that distribution.

If the following system of equations was written as a matrix equation in the form AX = C,? and matrix A was expressed in the for
Tomtit [17]

The value of the expression a - b + c + d will be 7.

<h3>What is the matrix?</h3>

A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The a_{ij} element in a matrix, such as M, refers to the i-th row and j-th column element.

The system of equations are given below.

5x + 7y = 7

3x - 2y = 9​

Then the equations can be written in the form of matrix. Then we have

\begin{bmatrix}5 & 7 \\3 & -2 \\\end{bmatrix} \begin{bmatrix}x \\y \\\end{bmatrix} = \begin{bmatrix}7 \\9 \\\end{bmatrix}

Then the value of a, b, c, and d will be

a = 5, b = 3, c = 7, and d = -2

Then  the value of the expression will be

a - b + c + d = 5 - 3 + 7 - 2

a - b + c + d = 12 - 5

a - b + c + d = 7

More about the matrix link is given below.
