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: Wages are flexible if the economy is self-regulating.
Explanation:
Classical economists believe that the economy is self-regulating. This means that if the economy is not at equilibrium, it will return to equilibrium if it is left without interference.
For this to happen, inputs such as wages have to flexible to enable them to adjust to market conditions and thus take the Economy back to equilibrium.
For instance, if there is a recession, wages will reduce so that the prices that the producers can charge will reduce as well which will enable supply to match demand and bring the economy back to equilibrium.
Personally, I would choose to save that money. The reason why is you never know - maybe something bad is going to happen and you will need that extra cash. So instead of splurging it on material things, it's better to save it for a rainy day, in my opinion. Investing is not safe, given that you may lose a lot more than you invest.

Explanation:
The Production possibilities frontiers is a curve that shows the various combination of two goods a company can produce when all its resources are fully utilised.
The PPF is concave to the origin. This means that as more quantities of a product is produced, the fewer resources it has available to produce another good. As a result, less of the other product would be produced. So, the opportunity cost of producing a good increase as more and more of that good is produced.
So, the PPF exhibits diminishing return. The slope of the PPF is different at different points. this makes the PPF a curve
the budget constraint is a straight line that shows the various combinations of goods a consumer can consume given her income. the budget constraint is a straight line because the slope is constant at each point on the curve
Also, the slope of the budget constraint is the relative prices of the two goods
Answer:
Capital Expenditure during the year 40,706
Explanation:
opening assets = 218470
less: Depriciation for the year = (42822)
less: Disposal of assets = (6943)
less: Closin Assets = (209411)
Balancing figure additions = 40706
