Answer:
- the sample mean is 44
- the sample standard deviation is 12.35
Step-by-step explanation:
given information:
data, 
= 36.45, 67.90, 38.77, 42.18, 26.72, 50.77, 39.0, 50.23
the number of data, n = 8
the sample mean, xbar
xbar = ∑/n
= (36.45+67.90+38.77+42.18+26.72+50.77+39.0+50.23)/8
= 352.08/8
= 44
standard deviation, s
s = 
= 
= 
= 12.35
Answer:
V = 402.12385mm
Step-by-step explanation:
When the diameter is 8mm, the radius is 4mm.
V = (π(4^2))8
V = (16π)8
V = (50.2654)8
V = 402.12385
V ≈ 402, 402.1, 402.12, 402.124
Answer:
-3x-8=16
-3x = 16+8
-3x = 24
x = 24/-3
x = -8
= -2(x-7)
= -2(-8-7)
= 30
Hope this helps you. Do mark me as brainliest.
