Answer:

The system of equations has no solution

Step-by-step explanation:

The method of substitution consists in solving one equation for a variable and replacing it in the other equation.

In this case one of the equations is already solved for one of the variables (y):

y = -2x + 1

So the next step is to plug this in the other equation wich is:

4x + 2y = -3

So we will have

4x + 2(-2x + 1) = -3

solving the parenthesis:

4x-4x -2= -3

-2= -3

wich is not a valid answer, so the system of equations has no solution.

Which statement below is incorrect?
Gre4nikov [31]

Answer: -The mean is not affected by the existence of an outlier.


Step-by-step explanation:

An outlier is an ultimate value in a set of data that is very much higher or lower than the other numbers. Mean is the only central tendency which is affected by the outlier. (It also affect the standard deviation)

It can affect the mean of a data set by skewing the results so that the mean is no longer representative of the data set.

The median and the interquartile range is unaffected by the existence of an outlier.
