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:
The correct answer is A. Test.
Explanation:
A test is different from an experiment: Before performing a test, there is an expected result. The test is performed to show this result. In an experiment, the result is open. Very often, tests are performed as part of an experiment.

In order for an individual to be considered unemployed, the individual must be over 18 years old, be currently out of job, but actively seeking a new job.
The current unemployment rate in the US is 3.7% (as of August 2019) while the unemployment rate in the EU is 6.2%.
In order for an individual to collect unemployment benefits, usually he or she must meet the following requisites:
- They must be out of work through no fault of their own.
- They must meet minimum earnings or job tenure requirements.
- They must be able, available, and actively seeking work.
Answer:
13.7%
Explanation:
The weight to be placed on preferred while computing the company's weighted average cost of capital (WACC) is the market value of the preferred stock divided by the market value of the company as a whole.
market of preferred stock=5,000*$26=$130,000
Market value of the company=market value of common stock+market value of preferred stock+market value of bond
common stock market value=12,000*$39=$468,000
market value of bond=$400,000*87%=$348,000
Weight of preferred stock=$130,000
/($130,000
+$468,000+$348,000)=0.137420719
=13.7%
