Answer:
The bottom 3 is separated by weight 7.8896 g and the top 3 is separated by weight 8.1904 g.
Step-by-step explanation:
We are given that
Mean, 
Standard deviation, 
We have to find the two weights that separate the top 3% and the bottom 3%.
Let x be the weight of machine components


=0.03
From z- table we get

Therefore, we get







Hence, the bottom 3 is separated by weight 7.8896 g and the top 3 is separated by weight 8.1904 g.
Step 1) Find the total circumference
C = pi x d
d = r x 2
d = 5 x 2 = 10
C = pi x 10 = 10pi
Step 2) Find 1/4 of the circumference
10pi / 4 = 2.5pi = 7.85
Step 3) Add the two radii sides to the 1/4 circumference
7.85 + 5 + 5 = 17.85
C = 17.85 feet
Hope this helps! :)

Answer:
Angle1:12
Angle2:168
Step-by-step explanation:
Angle 1+angle 2=180
X-9+8x=180
9x=189
x=21
angle1=21-9=12
Angle2=180-12=168
