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.

<span>To properly target potential customers, it is necessary to know not only what the needs are of the people they're advertising, they also need to know how the item will be used. There are multiple reasons that a customer would buy an item or service, so I assume media planners would need to use psychographic classifications to know who their target audience is and what they would like. How heavily planners rely on these classsifications probably effects the response they received from the audience.</span>
Answer:
8,000= fixed overhead
Explanation:
Giving the following information:
Bell’s Shop can make 1000 units of a necessary component with the following costs:
Direct Materials $24000
Direct Labor 6000
Variable Overhead 3000
Fixed Overhead ?
The company can purchase the 1000 units externally for $39000. The unavoidable fixed costs are $2000 if the units are purchased externally.
Buy= 41,000/1,000= $41
Total Unitary cost= 24,000 + 6,000 + 3,000 + fixed overhead
41,000= 33,000 + fixed overhead
8,000= fixed overhead
Option D
Employers can't fire an entire union because of the difficulty of replacing every worker best explains reason for unions give workers more power in contract negotiations
<h3><u>
Explanation:</u></h3>
One of the numerous significant advantages of getting collectively with your co-workers to create a union is obtaining the accuracy and protection of a union contract. A union contract is a printed contract among the employer and the employees that describes the phases and advantages in a sinless and legally-binding way.
The ability to be capable to recommend policy reforms or raise problems with a company as a whole preferably of just practicing them alone to a manager. A contract is not deemed to be in force till the membership has voted to approve it.
In most cases for this type of questions you would have to use a calculator, since this is not a value that can be approximated. Do you have an inverse normal function on your graphical calculator?
