For this case we have that by definition, the dimension of a matrix is given by:

<em>The number of rows by the number of columns </em>

It is observed that we have a column that consists of three rows.

\left[\begin{array}{c}6&\\2&\\8&\end{array}\right]

Thus, the dimension of the matrix is 3 * 1

Answer:

3 * 1

Option A

Answer: 3 x 1

There are 3 rows and 1 column. We write the number of rows first. The rows are laid out horizontally while the columns are vertical. We say this is a "3 by 1 matrix".

A bag contains 25 balls 20 of which are blue what percentage of balls are not blue
Artist 52 [7]

Answer:

20%

Step-by-step explanation:

20/25 = blue

This means 5/25 of the balls in the bag are NOT blue

(25-20 = 5)

We need to convert 5/25 to a percentage

\dfrac{5}{25} = \dfrac{5\times4}{25\times4}=\dfrac{20}{100}

% = per cent

"per" means "out of"

"cent" means "one hundred"

so

20/100 = 20%

If c is a positive integer, how does the graph of y=x+c compare to the graph of y=x?
Len [333]

Answer:

It is shifted c units to the left  .

Step-by-step explanation:

In general, adding a constant c to the value of x shifts a graph c units to the left.

The graph of y = x + c is parallel to y = x,  the y-intercept becomes (0, c) and the x-intercept becomes (-c, 0).

In the diagram below, the red line is the graph of y = x, and the blue line is the graph of y = x + 1.
