Answer:

data manipulation language

Explanation:

Data manipulation language (DML) is a family of similar syntactic elements used to select, insert, delete and update data in a database. Performing data read-only queries is sometimes considered a component of the DML.

The best known data manipulation language is the SQL (Structured Query Language) that is used to receive and manipulate data in a relational database. Other forms of DML are those used by IMS / DLI, CODASYL databases, such as IDMS and others.

Data manipulation languages comprise only the SQL statements that allow you to modify data, but not modify the schema or objects of the database. The manipulation using SQL statements of persistent database objects such as tables or stored procedures, is considered Data definition language and not Data manipulation language. In SQL these two categories are similar in their syntax, data types, expressions, etc., but they are different in their general function.

11111nata11111 [884]

Answer: 88.89 or 89

Explanation: Futures contract refers to a legal binding which obligates a buyer and seller to transact about a commodity, good, security or services at a predetermined price but goods are delivered or paid for in the future.

Given the following ;

Portfolio value(p) = $20million

Portfolio Beta (b) = 1.2

Index price (i) = 1080

Multiplier = 250

Future value(A) = index price × multiplier

Future value(A) = 1080 × 250 = 270000

Number of contracts (N) = (portfolio value × portfolio Beta) ÷ future value

N = ($20,000,000×1.2)÷270000

N = 24000000 ÷×270000

N = 88.8888=88.89

N = 89 (NEAREST whole number)

photoshop1234 [79]

Answer:

Explanation:

In my opinion, I would like to say that Clean Machines Company is correct. If you look at it this way, you'd see that there actually isn't any contract between Clean Machines Company and Dealer. When it came to about offers, the person offering is able to revoke an offer before the offer is even accepted. And he won't be held responsible unless of course, the offer is irrevocable. Then, to make the offer to be irrevocable, the Dealer then would have needed to prove that an option was present, or prove that the offer is was not able to be revoked due to UCC provision.
