What is the median of this set of data?
NA
66,51, 77, 68, 60, 75, 54, 80

The mean/average is 66.375

Step-by-step explanation:

To find the median, add all of the numbers together.  Then, divide the total amount of numbers from that.

Step 1:  Add all of the numbers together

66 + 51 + 77 + 68 + 60 + 75 + 54 + 80

531

Step 2:  Find out the total amount of numbers

66, 51, 77, 68, 60, 75, 54, 80

 1    2    3    4    5    6    7    8

There are 8 numbers

Step 3:  Find the mean/average

Total sum of numbers / Total amount of numbers

531 / 8

66.375

 The mean/average is 66.375

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
