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:
Stocks and Bonds
Yes. It is a rational behavior for individuals with a long-term investment horizon to choose to invest in bonds rather than investing in stocks despite the overwhelming "evidence that suggests that over long periods of time stocks still outperform bonds."
Rational behavior involves making rational choices that provide optimal levels of benefit or utility for the individual. People who make rational choices would rather choose bonds with lower risks and returns than stocks with higher risks and returns.
Explanation:
Every rational investor would prefer to reduce her risk exposure instead of increasing it. Every investor is also aware that investments with higher risks attract higher returns. However, determining the certainty of the returns is difficult.

The correct answers are letters: "A", "B", "C", and "D".
Explanation:
As a monopoly, Nature's Crunch will be benefited in profit terms if any chemical involved non-organic vegetables growing process is affected somehow. Then, <em>a tomato blight affecting chemically treated plants, an increase in the cost of chemical pesticides, and a new report about the environmental dangers of chemically treated plants</em> would automatically generate more sales for Nature's Crunch. Besides, it does not matter under what scenario, <em>income tax cuts</em> <em>for all consumers</em> will generate more revenue both for organic and non-organic industries.
