Answer:
The slope of a horizontal line is zero
Step-by-step explanation:
All horizontal lines are parallel to the x-axis.
The x-axis has a zero slope.
All parallel lines have the same slope.
Therefore the slope of a horizontal line is zero.
This means there is no rise in y.
So rise over run will become:
0/run=0
The missing number is 16
<em><u>Solution:</u></em>
Given that mean of data is 18
Let "x" be the missing number
The data set is:
21, 11, x , 27, 22, 13, 16
Sum of data set = 21 + 11 + x + 27 + 22 + 13 + 16
Sum of data set = 110 + x
<em><u>The mean is given by formula:</u></em>

Substituting the values we get,

Thus the missing number is 16
Angle DFB = (1/2)*[(arc CE)+(arc BD)]
Angle DFB = (1/2)*(84+38)
Angle DFB = (1/2)*122
Angle DFB = 61
(Angle DFB) + (angle DFE) = 180
angle DFE = 180 - (Angle DFB)
angle DFE = 180 - 61
angle DFE = 119 degrees

Final Answer is choice D) 119 degrees
