1) A modification problem takes places when creating a database two different type of information is entered in the same chart row generating inaccuracy. The only form to solve this issue is creating a new row so each piece of information will be stored in one row particularly.
2) There are three (3) types of modification problems: the deletion problem (<em>the single row containing information from different themes can be deleted losing data</em>), the update problem (<em>new information entered could lead to more inconsistency</em>), and the insertion problem (<em>similar to deletion, a new row can be inserted instead of the row causing problem but information will be missing</em>).
Answer and Explanation:
a. The crabs are a Common Good. They means can run out of supply if their use gets too much by society. Therefore, the decline of the Alaska king crab fishery can be explained by stating that the plenty types of boats such as those from California and Japan, has caused people to overfish, excessive fishing has brought about a decline in the supply of crabs.
b. There are 2 ways to avoid this
1. fishing permits have to be sold to the fishermen coming to fish for the crabs. Then the persons with the highest willingness to pay will come and buy the permits to fish.
2. Issuing just a particular amount of permits this would cause the fishermen to trade these permits. These open-market strategies have proved to be effective in organizing economic activity and are good stimulators in an economy.
c. They have been successful because regulations have been placed on fishing by the government. Also, if there are restrictions on other countries using up their spots and Canadians are the only ones fishing salmon, then there will be reduction in the decay rate of the population of the salmon, the salmon can easily repopulate, then Canadians would be able to come back the next year to fish again..
Answer:
Decrease in the interest rate
Explanation:
Present value is the sum of discounted cash flows
let me use an example to illustrate
the present value of $100 in year 0 discounted at 6% = $100
the present value of $100 one year from now discounted at 6% = $94.33
the present value of $100 two years from now discounted at 6% = $89
We can see that present value decreases with an increase in time
2. the present value of $100 one year from now discounted at 6% = $94.33
the present value of $90 one year from now discounted at 6% = $84.91
We can see that present value decreases with a decrease in the future value.
3. the present value of $100 one year from now discounted at 6% = $94.33
the present value of $100 one year from now discounted at 5% = $95.24
We can see that the lower the discount rate, the higher the present value
