Answer:
78
Step-by-step explanation:
The mean is the sum of the 5 numbers, divided by 5:
µ = (9 + 18 + 27 + 30 + x)/5 = (84 +x)/5 = 16.8 +x/5
The median of a 5-number set will be the middle number. Depending on the value of x, the mean/median may be 18, x, or 27, so we have three possible equations for x.
16.8 +x/5 = 18
x/5 = 1.2 . . . . . subtract 16.8
x = 6 . . . . . . . . multiply by 5
___
16.8 +x/5 = x
16.8 = 4/5x . . . . subtract x/5
21 = x . . . . . . . . . multiply by 5/4
___
16.8 +x/5 = 27
x/5 = 10.2 . . . . . . subtract 16.8
x = 51 . . . . . . . . . . multiply by 5
___
The sum of the possible values of x is ...
sum = 6 + 21 + 51 = 78

Answer:
Slope: 0
Step-by-step explanation:
We have to find the slope of the line with the given points.
To find the slope, we would use the slope formula: m = y2-y1/x2-x1, where as "m" is the slope.
Plug in your coordinates and solve.
Solve:
m = -7 - (-7)/-2 - 4
m = -7 + 7/-2 - 4
m = 0/-6
Divide -6 from 0.
m = 0
You would notice that we have a "0" in our slope. There is no "rise" in the slope.
This means that the slope of our line would be 0.
