A book club has 3 mailing lists:
- A special list M of the most senior active members.

sale.
If after the last mailing there was a request for too few copies, the secretary uses list R with probability
of ¼ and P with a probability of ¾.
If after the last mailing there was a satisfactory response, the secretary uses the R list and the P list with equal
probabilities.
If, after the preceding shipment, there was an excessive number of orders or over demand, the secretary uses list M with probability 1/3 and list P with probability ¾.
list M with probability 1/3 and R with probability 2/3.
If list M is used, there will be poor sales or satisfactory sales with equal probabilities; if list R is used, there will be poor sales with equal probabilities.
R, there will be poor sales with probability ¼ and satisfactory sales with probability ¾; if list P is used,
there will be satisfactory sales with probability 1/3 and over demand with probability 2/3.
In what proportion of the times are the sales sparse, satisfactory and over demand respectively?

- The National Bank of Erehwon handles money and maintains bank accounts on behalf of clients. A client is a person who does business with the bank. A client may have any number of accounts, and an account may belong to multiple clients (e.g., spouses, business partners). The client record is used for identification and contact data. For each account, the bank maintains the current balance on hand. Clients are identified by a five digit number starting with 10001.

- Complete questions 2-7 Note: Complete questions 2-7 in part B of the Garden Glory Project on p.129 and 130 of the textbook (8th edition). There may be more than one service performed at a property on a given date. Use this information when you answer questions. Comment on each question whether a given design is good and provide reasons for that. For example, the answer for Q1 is “This design is not appropriate because the designated Primary Key (PK) (PropertyName) in the table cannot determine some other attributes of the same table (e.g., ServiceDate, Description, Amount); in other words, the designated PK is not unique”. Your answers need to be specific and should clearly pinpoint the design problem with references to the relevant attributes in the table and the reason of violation. Any vague answer like “This design is bad because the PK is not good”, are wrong. Note that the foreign keys are italicized instead of dashed underlined. Clearly label answers for each question.…arrow_forwardA plan view sketch of a benchmark leveling run is shown below. Along each line representing a sight is the value of the rod reading for that sight. The numbering of TPs shows the direction of the level run. Place the data in the form of field notes.

When new vehicles arrive at HTV, a new vehicle record is created. Included in the new vehicle record are a vehicle serial number, name, model, year, manufacturer, and base cost. When a customer arrives at HTV, he or she works with a salesperson to negotiate a vehicle purchase. When a purchase has been agreed upon, a sales invoice is completed by the salesperson. The invoice summarizes the purchase, including full customer information, information on the trade-in vehicle (if any), the trade-in allowance, and information on the purchased vehicle. The invoice also summarizes the final negotiated price, plus any applicable taxes and license fees. If the customer requests dealer-installed options (simply options), they are listed on the invoice as well. A customer may decide to have no options added to the vehicle or may choose to add many options. Dealer-installed options are described by an option code,…arrow_forward
