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.

P(x)=-30x^2+9000x-567000
Explanation:
First, we need to remember the parts of a Profit function. A profit a business makes equals revenue (R(x)) minus its costs (C(x)). So
There are two parts
1. Revenue: which is equal to the number of units sold times the price:
where x is the price you charge and Q(x) is the number of shirts that can be sold. Then
2. Cost. The cost function is directly given by the question
Putting this together we have
