What is the mean of the data set? 125, 141, 213, 155, 281 126.80 158.00 183.00 228.75

The mean of data set = 183

Step-by-step explanation:

Formula:

Mean of a data set is given by,

Mean = (sum of all data set)/(total number of data set)

To find total sum of data set

Here data set is,

125, 141, 213, 155, 281

Sum = (125 + 141 + 213 + 155 + 281) = 915

To find the mean of data set

Total sum = 915 and total number = 5

Mean = (sum of all data set)/(total number of data set)

Mean = 915/5 = 183

Therefore mean of data set = 183

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
