The probability that demand is greater than 1800 gallons over a 2 hour period is : 0.5
<u>Given data :</u>
Mean value of gasoline per hour = 875 gallons
Standard deviation = 55 gallons
<h3>Determine the probability of demand being greater than 1800 gallons over 2 hours </h3>
Demand for gas in 1 hour = X₁
Demand for gas in 2 hours = X₁ + X₂
Therefore ; ( X₁ + X₂) ~ N ( u₁+u₂, sd₁² + sd₂² )
In order to calculate probabilities for normals apply the equation below
Z = ( X- u ) / sd
where : u = 1800, sd = √ ( 55² + 55² ) = 77.78
using the z-table
P( Y > 1800) = P( Z > ( 1800 - 1800 ) / 77.78)
= P( Z>0 ) = 0.5
Hence we can conclude that The probability that demand is greater than 1800 gallons over a 2 hour period is : 0.5.

Answer:
It is called A PERMANENT FUND.
Explanation: A PERMANENT FUND is a type of governmental fund that is used to record and account for endowments such as gifts for government or non governmental organisations.
This fund often times is used in financing civic projects, facilities owned by the city concerned and the likes.
The process is a multiplicative inverse of which people seem to check
Explanation:
The global environment affects all of the other environmental influences such as the economic, legal, and social environments because: the increase in free trade among nations and technological changes have created globalization and increased competition.
