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:
a. reserve requirements, the discount rate, and open-market operations.
Explanation:
Monetary policy can be defined as the actions (macroeconomic policies) adopted and undertaken by the central bank of a particular country to control the money supply and interest rates so as to boost or enhance economic growth. The central bank uses monetary policies to manage inflation, economic growth through long-term interest rates and level of unemployment in a country. In order to boost economic growth, monetary policy is used to increase money supply (liquidity) while it is also used to prevent inflation by reducing money supply.
Additionally, money supply comprises of checks, cash, money market mutual funds (MMF) and credit (mortgage, bonds and loans).
The three (3) primary policy tools available to the governmental officials in charge of our country's monetary policy are reserve requirements, the discount rate, and open-market operations.

Answer:
Variable manufacturing overhead rate variance= $664 favorable
Explanation:
Giving the following information:
Variable overhead 0.2 hours $ 5.10 per hour
The company used 1,660 direct labor-hours to produce this output. The actual variable overhead cost was $7,802.
<u>To calculate the variable overhead rate variance, we need to use the following formula:</u>
Variable manufacturing overhead rate variance= (standard rate - actual rate)* actual quantity
Actual rate= 7,802/1,660= $4.7
Variable manufacturing overhead rate variance= (5.1 - 4.7)*1,660
Variable manufacturing overhead rate variance= $664 favorable
