A data sample is a set of data collected and/or selected from a statistical population by a defined procedure, in statistics and quantitative research methodology. the elements of a sample are known as sample points, sampling units or observations. Cluster sample is a simple random sample of groups, or clusters, of the population often based on geography. In this case, this is a type of cluster sample.
Answer:
$9 billion
Explanation:
Calculation to determine what The commercial banking system has excess reserves of
Using this formula
Excess Reserve= Net Worth Reserves -Required reserve
Let plug in the formula
Excess Reserve=$51 billion - (.30*$140 billion)
Excess Reserve=$51 billion-$42 billion
Excess Reserve=$9 billion
Therefore The commercial banking system has excess reserves of $9 billion
Answer:
$10.67
Explanation:
Data provided in the question:
Initial cost = $3
Initial selling cost = $5
Initial sales = 4000
with $1 increase in price she loses 300 sales per month
Now,
Let the increase in price which maximizes the profit be '$x'
Therefore,
Final selling price = $5 + x
Final sales = 4000 - 300x
Thus,
Revenue = Final selling price × Final sales
= ( 5 + x)( 4000 - 300x)
= 20,000 - 1500x + 4000x - 300x²
= 20,000 + 2500x - 300x²
Total Cost = Initial cost × Final sales
= 3(4000 - 300x )
= 12,000 - 900x
Now,
Profit = Total revenue - Total cost
or
P = [ 20,000 + 2500x - 300x² ] - [ 12,000 - 900x ]
or
P = 8,000 + 3400x - 300x²
for point of maxima 
Thus,
0 = 0 + 3400 - 300(2x)
or
0 = 3400 - 600x
or
600x = 3400
or
x = 
Hence,
The price will be = $5 + x = 
= $10.67
Answer:
Line production system
Scale of production
Development of Factories
Development of Capital Machinery
Development of Capital Goods Industry.
Explanation:
Line production system: This system was adopted in manufacturing companies to divide the tasks between the workers so a product can be manufactured in the fastest way possible
Scale of production: The manufacturing industry develop high levels of production that allow surpluses of production of goods in the economy.
Development of Factories: The manufacturing industry was the first in organize the Plant for production purposes. Therefore, the creation of what is nowadays known as factories was a consequence of this organization.
Development of Capital Machinery: Manufacturers Researched and developed new machines to improve the times of production. With time this technology was used for more industries to achieve fast performances.
Development of Capital Goods Industry: As machines were developed the industry of Capital goods arose and became an important source of technology for companies.
