Marat540 [252]
<h2>Answer:</h2>

This relation is a function because a function, in fact this is a linear function. We have that:

\left[\begin{array}{cc}x & y\\2 & 3\\4 & 4\\6 & 5\\8 & 6\end{array}\right]

As you can see below, all the points have been plotted an this is a linear function. Therefore, with two points we can get the equation, so:

The \ equation \ of \ the \ line \ with \ slope \ m \\ passing \ through \ the \ point \ (x_{1},y_{1}) \ is:\\ \\ y-y_{1}=m(x-x_{1}) \\ \\ \\ y-3=\frac{4-3}{4-2}(x-2) \\ \\ \\ y-3=\frac{1}{2}(x-2) \\ \\ y=\frac{1}{2}x-1+3 \\ \\ y=\frac{1}{2}x+2 \\ \\ \\ Where: \\ \\ (x_{1},y_{1})=(2,3) \\ \\ (x_{2},y_{2})=(4,4)

Finally, the equation is:

\boxed{y=\frac{1}{2}x+2}

Which one of these data sets has a mean that is different from the others?
Kamila [148]

Answer:

The top right graph.

Step-by-step explanation:

If you find the mean for all the graphs you get:

Graph 1: 7                                         Graph 2: 2

Graph 2: 7                                        Graph 4: 7

To find the mean you all all the numbers up and divide it by the number of data points for example heres the first graph:

8 + 8 +8 +8 +8 +8 +1 = 49    Add the data points

49 / 7 = 7                              Divide by the total amount of points which is seven
