<h3>What is the frequency about?</h3>

The relative cumulative frequency of students in the question is seen as those who earned a score of 20 to be 0.68 or 68 %.

From the question, The cumulative frequency of students who earned a score of 20 or lower on the quiz is:

= 4+8+15+7

=34.

Total frequency is:

= 4+8+15+7+7+3+4+2

=50.

Therefore, the relative cumulative frequency is:

= 34/50

= 0.68

= 68%

Hence, The cumulative frequency of students who earned a score of 20 or lower on the quiz is option d) 68.

Which property is shown in the matrix addition below?<br> [-6 15 -2 ] + [6 -15 2 ] = [0 0 0

aksik [14]

Answer:

The property shown in matrix addition given is "Additive Inverse Property"

Step-by-step explanation:

First of all lets define what a matrix is.

A matrix is an array of rows and columns that consists of numbers. There are several types of matrices. The one in our question is a row matrix which consists of only one row.

There are several addition properties for matrices.

One of them is additive inverse property. The additive inverse of a matrix consists of the same elements but their signs are changed.

Additive inverse property states that the sum of a matrix and its additive inverse is a zero matrix.

$\left[\begin{array}{ccc}-6&15&-2\end{array}\right] + \left[\begin{array}{ccc}6&-15&2\end{array}\right] = \left[\begin{array}{ccc}0&0&0\end{array}\right]$

Hence,

The property shown in matrix addition given is "Additive Inverse Property"
