Answer:
i8765
Step-by-step explanation:
X=32
Explanation: X/9-1=4
X/8=4
8x4=32
Answer: 2.28%
Step-by-step explanation:
μ = 71.8
σ = 3.4
X < 65
P(X < 65) = P (Z < 65 - 71.8/3.4) = P (Z < -2)
According to the table for the normal distribution attached, it will give us
P (z < Z < 0), this way, to find the P(Z < z), we need to do 0.5 - P:
0.5 - P(-2 < Z < 0) = 0.5 - 0.4772 = 0.0228
In percentage: 0.0228*100 = 2.28%
Answer: 708017151.707 m^3
Step-by-step explanation:
Volume of a sphere has the equation of
V=4/3(pi)r*r*r=4/3(pi)r^3
r=553 m
4/3(pi)553*553*553=4/3(pi)553^3=4/3(pi)169112377
=676449508/3(pi)=225483169.333(pi)=708017151.707 m^3
Where pi=3.14
