Well the increase is 132/120. Simplify by dividing 12 from the numerator and the denominator, you should get 11/10.
11/10 is also 110%
Answer:
a. mean = 820; standard deviation = 57.74
b.0.75 or 75%
Step-by-step explanation:
Lower limit (L) = 720
Upper limit (U) =920
a.The mean of an uniform distribution is given by:
![\mu = \frac{L+U}{2}=\frac{720+920}{2}\\ \mu = 820](https://tex.z-dn.net/?f=%5Cmu%20%3D%20%5Cfrac%7BL%2BU%7D%7B2%7D%3D%5Cfrac%7B720%2B920%7D%7B2%7D%5C%5C%20%5Cmu%20%3D%20820)
The standard deviation of an uniform distribution is given by:
![\sigma = \frac{U-L}{\sqrt{12}} = \frac{920-720}{\sqrt{12}}\\\sigma=57.74](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Cfrac%7BU-L%7D%7B%5Csqrt%7B12%7D%7D%20%3D%20%5Cfrac%7B920-720%7D%7B%5Csqrt%7B12%7D%7D%5C%5C%5Csigma%3D57.74)
b. The probaility that X is less 870 is:
![P(X](https://tex.z-dn.net/?f=P%28X%3C870%29%20%3D%20%5Cfrac%7B870-L%7D%7BU-L%7D%3D%20%5Cfrac%7B870-720%7D%7B920-720%7D%20%5C%5CP%28X%3C870%29%20%3D%200.75%5C%20or%5C%2075%5C%25)
Answer: 1306.5 m^3
Step-by-step explanation:
1. The formula for the volume of a cylinder is: V=
r^2h
2. If you substitute the values into the equation, you get
V = pi * 5.7^2 * 12.8 = 1306.5
3. 1306.5 is already to the nearest tenth, so that is the answer.
