Which of the following will be the solution for a two-order inequality?
2 answers:
In solving a two-order linear inequality, say
and 
We graph the corresponding linear equations;
Each of the two equations divides the cartesian plane into half-planes.
By testing for points, we identify the half-plane that satisfies each inequality.
The intersection of the two half-planes gives us a set of points that satisfies the two inequalities simultaneously.
Therefore the solution to the two-order inequality is the intersection of two half-planes.
The correct answer is option C

Answer:
c) skewed to the right.
Step-by-step explanation:
We need to remember that is a distribution is skewed to the right then we have the following condition satisfied:
And if is skewed to the left then we have:
If the distribution is symmetric we need to satisfy:
For this case since we have most of the values between 200000 and 500000 when we put atypical values like 15000000 that would affect the sample mean and on this case the sample mean would larger than the sample median because the median is a robust measure of central tendency not affected by outliers.
So for this special case we can say that the . And probably the median would be higher than the mode so then we can conclude that the best answer for this case would be:
c) skewed to the right.
