Sort the numbers in ascending or descending order, then eliminate the greatest and least numbers until you're left with the middle two. The median is the average of the last two numbers.
For example, the median for the set

is 3 because the middle two numbers are 2 and 4, and their average is

.
Turn the feet into meters 1 meter = 100cm and if there is 12cms in a foot than divide 100cm by 12cm and you get 8.3ft
Length(width + 30)=15,000 square meters, so the equation is l(w+30)=15,000, either 15,000 or 1,500 i cannot tell which number you were meaning to say because of where your comma is placed.
The slope is 2.
Equation if needed: y= 2x + 1
In statistics, an outlier is an observation point that is distant from other observations. These extreme values need not necessarily impact the model performance or accuracy, but when they do they are called “Influential” points. Note: An outlier is a data point that diverges from an overall pattern in a sample.
