I’m not sure on this at all. Anybody who can help?

The mean of the data set with outlier = 16

The mean of the data set without outlier = 13

Step-by-step explanation:

The mean is also sometimes called the average, to find the mean, you add up every number in the data set, and you divide that sum by the total number of data points within the set.

Given: The data set 12 , 14 , 15 , 28 , 11

Arranging the data in order from the least to the greatest

11 , 12 , 14 , 15 , 28

The number of data set = 5

The sum of the data set = 11 + 12 + 14 + 15 + 28 = 80

So, the mean = 80/5 = 16

The outlier of the data set is 28 because most of the date between 11 , 15

The data without outlier are: 11 , 12 , 14 , 15

The number of data set = 4

The sum of the data set = 11 + 12 + 14 + 15 = 52

So, the mean = 52/4 = 13

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
