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:
Three levels of information systems at university include:
1. The students ICT unit (workgroup)
2. The departmental ICT units (enterprise)
3. The examination and records unit (inter enterprise)
Explanation:
The students ICT units and lab works together by communicating with one another in terms of file transfer, content chat systems and temporal record I keeping and processing.
The departmental information system operates at the higher level as an enterprise because at this stage the users at the work stations can no longer have full access to the platform because it is redefined to accommodate academic and non academic staff who are very useful in managing the data content, as well as keeping the security of these content intact against any form of security threats.
The examination and records unit on the final and higher level is the home server for all information systems security, backup and archive and the communication level regarded as the inter enterprise units. It is the final resort point when every other means of information and record keeping becomes threatened. Hence it is seen as the collation, record keeping and transfer point between one enterprise or department to the other.
Answer:
The answer is C.
Explanation:
It will not be proper to just choose the balance in the cash ledger or the one in the bank because the balance as per the cash ledger in the book might be different from the balance in the bank statement in the bank.
So to eliminate this differentiation, bank reconciliation needs to be done. After this reconciliation has been carefully done, the adjusted cash balance in the reconciliation will be used.
Answer:
35 times
Explanation:
The price-earnings ratio is the financial ratio that compares the market price of a share with its earnings in order to determine whether the share gives earnings that makes it a good buy.
Price-earnings ratio=market price per share/earnings per share
market price per share for 2017 is $42
earnings per share=net income-dividends/average common stock outstanding
net income is $108,000
dividends is nil
average number of common stock is 90,000
earnings per share=$108,000-$0/90,000=$1.2
price earnings ratio=$42/$1.2=35 times
The characteristic that the manager needs to assess of the subordinate prior to delegating responsibilities is:
The type of leadership training that is being provided by the human resource director is:
<h3>What is Situational Leadership?</h3>
