Answer:
-9/11
Step-by-step explanation:
slope is change in y/change in x
change in y is 9 (12-3)
change in x is -11 (-17--8)
slope is -9/11
Answer:
Mean=

Variance=

Step-by-step explanation:
Given is the uniform distribution
x=0.15,y=0.19
where x and y are lower and upper values.
mean=(x+y)/2
mean=(0.19+0.15)/2
Mean=0.17 mm
Now using equation
variance =
For variance take a=15,b=19
Variance=
Variance=2

Answer:
103
Step-by-step explanation:
The answer is 103 since it is the middle number when the data is arranged in ascending or descending order.
Answer:
sum of angles at a point is equal to 360
so, 360= 163+ x°+ y°+z°
y°=360-163 -x° - z°
y°=197- x° -z°
