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: Option C
Explanation: In a monopolistic competition market structure, there are many producers selling their products and each product is not a perfect substitute of the other.
The number of producers are large but each operate at a relatively smaller level. The products offered in the market are similar but not identical.
Hence, from the above explanation we can conclude that option C is correct.
The answer is data backup and collaboration.
Answer: C - Crowdfunding
Explanation: Investors, loans, and selling products and services would not gain them enough financial support, whereas crowdfunding will in an efficient way.
To obtain $225,000 in 18 years it is necessary to save or invest at least 1,041.66 every month and 12,500 every year.
We know the total money that needs to be saved to cover college education is $225,000 and the time to save up this money is 18 years. Based on these two details, let's find out how much you need to save every month and every year.
Total of months:
- 12 months x 18 years = 216 months.
The total you need to save per month:
- $225,000 / 216 = 1,041.66.
The total you need to save per year:
- 1,041.66 x 12 = 12,499.99 that can be rounded as 12,500.
