Answer:
All : 1st, 2nd, 3rd are False
Explanation:
1. Average total cost is always greater than average variable cost by a constant amount : False.
Average Total Cost (ATC) is the total cost per unit of output. ATC = Average Variable cost (AVC) + Average fixed cost (AFC). Total fixed cost (TFC) is the cost which stays same at all levels, AFC = TFC / Q falls with increasing output. So, ATC is greater by AVC, by AFC (decreasing) amount.
2. In the short run, a perfectly competitive firm always maximises profit when average total cost is at minimum : False
A perfectly competitive firm maximises profit in short run when difference between its Total Revenue & Total cost is maximum, Marginal Revenue = Marginal Cost & MC > MR after the point.
3. If a firm shuts down in the short run, its profits will equal zero : False
A firm shuts down in short run, when its price < average variable cost, or firm's average revenue < average variable cost. This implies that firm must be incurring losses, if it shuts down.
Answer:
DIVISION OF LABOUR
Explanation:
Division of labour is : allocating different subparts of a task process to different people, to attain better efficiency. Better efficiency is attained by - labourers being specifically specialised in that subsection task, which increases their individual & hence organisation efficiency.
Elisa: opening her new business & assigning tasks to employees - is an example of the same.
All other options are inapt because: Management departmentalisation is dividing organisation into specialised niche departments. Mass production economies is cost reduction due to bulk quantity production. Specialisation of priorities is developing competitive advantage by research & innovation.
Answer:
$80,704
Explanation:
Data provided in the question:
Budgeted Price = $20,176 per pool
Budgeted quantity = 12 pools
Actual quantity = 16 pools
Actual price = $20,992 per pool
Now,
Sales Volume Variance
= ( Actual Quantity - Budgeted Quantity) × Budgeted price
Thus,
Sales Volume Variance for April = ( 16 - 12 ) × $20,176
or
Sales Volume Variance for April = $80,704
Answer:
Option D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $151 and $216.
Explanation:
A confidence interval is a range of values, derived from the sample statistics, which may include the value of an unknown population parameter.
A 95% confidence interval indicates that between 152 of 160 samples (95%) of the same population will produce confidence intervals that will contain the population parameter.
It also means that we have a 95% confidence that the average (average amount) is among the resulting amounts obtained.
Logically, option "D" is missing the final part. This would be: D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $ 15.
This is the only true option, since the test is based on a sample of only 160 households, the entire population of households cannot be included.
Hence, the correct option is:
Option D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $151 and $216.
Answer:
The Global Economic Crisis
Factors that led to the Mortgage Crisis include all:
A) Mortgages were accessible for borrowers who did not meet income and minimum down payment requirements. Moreover, the Fed kept interest rates really low to prevent a recession. This led to a decrease in the demand for homes and a further decline in housing prices.
B) The total amount of risk embedded in the securities created by bundling mortgages did not change. The securitization and resecuritization processes led to a distribution of total risk among different types of collateralized securities.
C) Mortgage payments based on short-term interest rates-called adjustable-rate mortgages (ARMs)—were preferred by subprime borrowers.
D) Rating agencies, such as Moody's and Standard & Poor's, earned fees from securitizing agencies for providing ratings for CDOs. The securitizing agencies were looking for higher ratings for their CDOs, and the rating agencies were earning fees. This led to a conflict of interest; thus, ratings did not reflect the true risk involved in the CDOs, which were backed by mortgages.
Explanation:
Hedge funds, banks, and insurance companies helped to cause the subprime mortgage meltdown while regulators looked the other way. They were given free rein to construct so many complex securities which somehow contributed to the mortgage defaults with financial institutions skimming fees during the securitization processes, and mortgages were made accessible for borrowers who did not meet the income and minimum down payment requirements.
