In planning the database it is important to consider- what each table is 'about'.
Explanation: It becomes very important so that any sort of duplicate data can be avoided. These databases are the source which provides the information. It should be segregated into several subject based tables. Basically, databases provides the access to the accurate information and to provide accuracy one must be careful while creating. Every table is anyhow related to another.
Answer:
1. Annual demand ( D) = 100,000 bags
Ordering cost per order (Co) = $15
Holding cost per item per annum (H) = 15% x $2 = $0.30
EOQ = √<u>2DCo</u>
H
EOQ = √<u>2 x 100,000 x $15</u>
0.30
EOQ = 3,162 units
2. Maximum inventory
= Safety stock + EOQ
= 1,500 + 3,162
= 4,662 units
3. Average inventory
= EOQ/2
= <u>3,162</u>
2
= 1,581 units
4. Number of order
= <u>Annual demand</u>
EOQ
= <u>100,000</u>
3,162
= 32 times
Explanation:
EOQ is the square root of 2 multiplied by annual demand and ordering cost per order divided by holding cost per item per annum.
Maximum inventory is the aggregate of safety stock and EOQ.
Average inventory is economic order quantity divided by 2
Number of order is the ratio of annual demand to economic order quantity.
Answer:
Explanation:
A heart transplant is a surgical procedure that replaces the person’s heart with a donor heart. A person may require a heart transplant for several reasons including congenital, arterial and muscle diseases or for unforeseen reasons such as accidents or viral infections.
The donor heart is matched to the recipient by blood type. More variables are also used to decide which recipient receives a heart if there are not enough hearts available for all recipients waiting for a transplant. The variables included in the decision may include the recipient state of health, cause of the heart condition and the urgency of the transplant.
The main goal of this project is for you to write a matching function that receives as a parameter the number of available hearts for transplant and will output all the recipients ranked in order of precedence.

Explanation:
Marginal utility is an economic concept that says that a consumer recieves more marginal utility in the first consumption of a good or services than in the second and the subsequents. In fact with each consumption the marginal utility reduces, this effect is known as diminishing marginal utility.
One of the the methods to reduce the effects of the diminishing marginal utility is to reduces prices. As the utility of a product decreases as its consumption increases, consumers are willing to pay smaller amount of money for more of the product.
Answer (A):
Need more data to select the better adviser
<u>Explanation: </u>
Adviser A averaged 19% return on the investment which is more than that of Adviser B who averaged 16% return on investment. However, adviser A has a beta of 1.5 which is also greater than that of Adviser B who has a beta of 1. This means that adviser A made a more riskier investment and hence a higher average return on investment. We need more data to tell which adviser performed better in relation to each other.
Answer (B):
Investment Adviser B
<u>Explanation:</u>
= T-bill rate = 6%
= Market return = 14%
= Market risk premium = 14% - 6% = 8%
= Average Return by Adviser A =19%
= Beta of Adviser A = 1.5
= Average Return by Adviser B =16%
= Beta of Adviser B = 1
CAPM Equation is 
<u>For Adviser A</u>
= 6 + 1.5 (14 - 6) = 18%
The expected average return for the investment is 18% which means that Adviser A over performed the market by 1 %
<u>For Adviser B</u>
= 6 + 1 (14 - 6) = 14%
The expected average return for the investment is 14% which means that the Adviser B over performed the market by 2 %
Clearly, Adviser B performed better than Adviser A.
Answer (C):
Adviser B
