Answer:
<h2>The probability is 58 %.</h2>Step-by-step explanation:
This problem belong to a normal distribution probability.
Mean = 63.6
Standard Deviation = 2.5.
We have to find the probability of a height greater than 63.0.
Due to the normal probability, we need to find the Z score first:
; where x is the height, u is the mean, and o is the standard deviation.
Once we have our Z score, we find the probability with the z-table (attached). So, for a z score of -0.24 we have a probability of 0.42.
But, the problem is asking for height greater than 63.0, this mean that we have to subtract 0.42 from 1, giving as result 0.58, which means a 58% of probability,
Answer:
5430.85 square feet
Step-by-step explanation:
Height of the cylindrical part of the cilo = 25 feet
radius of the base cylindrical part of cilo = 8 feet
Now volume of cylindrical part of cilo =
Volume of cylindrical part of cilo = =
Now,
Height of the conical part of cilo = 6 feet
Radius of the conical part of cilo = 8 feet
Volume of the conical part of cilo = =
Volume of the entire cilo =
since
volume of entire cilo = = 5430.85
