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:
Cash provided by operating activities =$28,700.
Explanation:
Look at attachment for step by step guide.
Answer:
False
Explanation:
Whenever, there will be reduced production costs, due to any reason in the economy, then the goods will be cheaper and accordingly the sale will be in abundance assuming other factors remain constant.
Thus, due to subsidies the cost to producers will be less and then exporters will not be able to get more share as domestic goods will cost cheaper.
Thus, there will not be any gain to foreign competitors in our domestic markets, as they will not get any share extra rather they will loose as a foreign competitor. In fact goods which are exported will also cost low, and therefore, will gain new customers.
Therefore, above stated statement is false.
Answer:
(a) GDP is a dependent variable and aggregate net investment is a independent variable. There is a positive relationship between the variables which means that an increase in the net investment will lead to increase GDP.
(b) There is a negative relationship between the variables which means that as the supply of wheat increases, as a result price of wheat falls. So, as the number of acres of wheat planted in a season increases as a result price of wheat decline.
(c) There is a negative relationship between the variables which means that an increase in the interest rate in an economy will lead to increase the cost of borrowings and hence, net investment falls.
(d) There is a negative relationship between the variables because of the law of demand. It states that an increase in the price of a commodity will lead to reduce the quantity demanded for that commodity.
(e) There is no relationship between these variables. Both the variables are totally uncorrelated.
None of those answers are suitable to me.
Government bonds are generally regarded as low-risk and they typically have modest (low) interest rates for return on investment, and these are advantages really. So we can discount answer A, C, and D.
I guess you could say that bonds can be hard to find (Answer B) but this not really true. There is always a bond market to trade bonds on. It requires setting up a trading account or speaking to a broker so this can be more difficult than putting money in a bank account, but to be honest I don't think any of those answers are appropriate for the question.
