Answer:
(a) (i) Define the term "Green Revolution" as used during the period 1945 to 1985.
- The use of modern agricultural techniques became widespread around many regions in the world. This led to higher yields through the use of fertilizers, pesticides, genetically modified seeds and mechanical machinery.
(ii) Explain the principal agricultural practices/technologies associated with the green revolution.
- extensive use of fertilizers, pesticides, genetically modified seeds and mechanical machinery.
(iii) Name TWO regions, in different parts of the world, where the green revolution has had a significant impact on crop yields.
- In North America, Mexican food production increased and they stopped importing food. Although currently that has reversed, and it is importing even more food than before.
- In Brazil, agricultural production increased dramatically. Both total farmed area and yields have continued to increase in the past years becoming a threat to the amazon basin.
(b) Identify and discuss TWO social, political, or cultural conditions necessary for the success of the agricultural practices/technologies of the green revolution.
- Emigration from rural areas to urban areas which resulted in a rapid expansion of urban centers. Since less labor was needed in farms, many people left rural areas due to lack of jobs.
- People started accepting genetically modified crops, which were not well accepted at first. A lot of money was invested in research and development of new seeds, fertilizers and pesticides.
(c) Identify and discuss TWO significant economic or ecological factors that may limit the long-term success of the agricultural practices/technologies of the green revolution.
- Many new agricultural techniques have resulted in a decrease of soil fertility. In many places crops cannot grow unless a lot of fertilizer is used.
- Countries were the green revolution was originally successful, like Mexico (where it started), have reduced the total area dedicated to crops. As the yields increased, the price of food started to decrease and many small farms could not keep operating.
Answer: 20 women
Explanation:
Making the total number of women in the club 'x', we can then do the following,
Total Number of Names in Hat, N
N = x + 10 ( total number of men)
therefore total number of names in the hat N=x+10
We need to select 3 people so sample size = 3
Using the Hypergeometric Distribution then we can then use the formula,
Expected number of women on the Committee = k * n / N
Where k is the total number
2 = x * 3 / (x + 10)
2 = 3x/(x +10)
3x = 2x +20
x = 20
There are 20 women in the club.
I think the answer is <span>unit-elastic over this price range. This happens when a company earns the same revenue even with some slight changes on the prices. It means that slight increase or even decrease in price does not affect the revenue of the company.</span>
Answer:
The average inventory which HG should carry during the year is 5,000 units.
Explanation:
Economic Order Quantity is the ideal inventory procurement which minimizes holding and ordering cost. The EOQ is used by businesses in order to determine the best possible inventory holding.
EOQ = 
EOQ = 
EOQ = 5,000 units
Answer:
Standard deviation = 47.69% (Approx)
Explanation:
Given:
Portfolio of Apple stock w1 = 25% = 0.25
Portfolio of Tesla stock w2 = 75% = 0.75
Standard deviation return Apple σ1 = 35% = 0.35
Standard deviation return Tesla σ2 = 60% = 0.60
Correlation coefficient ρ12 = 0.22
Find:
Standard deviation
Computation:
Standard deviation = √w1²σ1² + w2²σ2² + 2w1σ1w2σ2ρ12
Standard deviation = 0.4769
Standard deviation = 47.69% (Approx)
