Answer: Collinear, equidistance, and noncoplanar
Step-by-step explanation:
Angle 56 is vertical to the blank angle so that means they are equal.
So now 56, 41 and x create a straight line, so they are equal to 180.
180 = 56 + 41 + x
180 = 97 + x
83 = x
Hope this helps :)
Answer:
Step-by-step explanation:
First, find the mean ; (32+45+33+22+50+48) / 6 = 230/6
Mean = 38.33
Variance =
n = sample size
Variance = 
Variance = 
= 
= 121.8667
Therefore, variance = 121.87
