For the data set table 65, 75, 64, 20, 80, 125. what is the mean of this data set table?

71.5

Step-by-step explanation:

Mean = Sum of data values/How many data values

65+75+64+20+80+125= 429

There are 6 data values in this data set.

429/6 = 71.5

Mean=71.5

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
