Step-by-step explanation:

16 data points.

the mean value is the sum of all data points divided by the number of data points :

13896/16 = 868.5

the median is the data point with half of the other data points being smaller and the other half being bigger.

as we have an even number of data points, we need to apply the extra rule :

the median is the mean value between the 2 middle points (where one half of the other data points is smaller than these 2, and the other half is bigger than these 2).

in our case we have 138 and 240.

the mean value between these 2 and therefore the median of the list is

(138 + 240)/2 = 378/2 = 189

Which equation can pair with x-y=-2 to create a consistent and dependent system?

MrRissso [65]

See the explanation

<h2>Explanation:</h2>

A system that has one or infinitely many solutions is called <em>consistent. </em>If an equation in a system tells us no new information then the equations of the system are <em>dependent. </em>In other words, to find an equation that creates a consistent and dependent system with the given equation we have to get the same line:

The given line is:

$x-y=-2$

If we multiply both sides of the equation by a constant we will have the same line when plotting, therefore let's multiply by 3:

$3(x-y)=3(-2) \\ \\ 3x-3y=-6$

So a system of two linear equation that is consistent and dependent is:

$\left \{ {{x-y=-2} \atop {3x-3y=-6}} \right.$

What is the value of this expression? 100 - [(5 x 3 + 4)]

shepuryov [24]

Answer:

Step-by-step explanation:

Order of operations rules require that we do the work inside parentheses first. Multiplication must be done before addition. Thus, the quantity inside parentheses becomes 15 + 4 = 19.

Next, we evaluate 100 - [19], obtaining 81 (answer)
