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.

S_A_V [24]

Answer:

a) maximize 12x+16y subject to x+y≤60; x+2y≤80; 2x-3y≥0; x-9y≤0.

b) 40 fish and 20 beef dinners

c) $800

Explanation:

Let x and y represent the numbers of fish and beef dinners to prepare, respectively. Then the relations these values must satisfy are ...

x + y ≤ 60 . . . . . a maximum of 60 dinners will be sold

0.25x + 0.50y ≤ 20 . . . . . kitchen hours cannot exceed 20

x/y ≥ 3/2 . . . . . . at least 3 fish dinners for each 2 beef dinners will be sold

y ≥ 0.10(x +y) . . . . at least 10% of dinners sold will be beef

While satisfying these relations, we want to maximize the profit function:

p = 12x +16y

a) The linear programming problem can be formulated as ...

Maximize 12x +16y, subject to ...

x + y ≤ 60
x + 2y ≤ 80
2x - 3y ≥ 0
x - 9y ≤ 0

b) The graph shows the constraint inequalities with the comparison symbol reversed. The effect of that is to shade the area that is NOT part of the solution set, leaving the feasible region white. The vertex of the (white) feasible region that makes the profit line farthest from the origin is the solution we're looking for. Once the profit line is plotted so we can compare its slope to the lines bounding the feasible region, it becomes clear which vertex is the one that maximizes profit.

The solution is (x, y) = (40, 20).

40 fish dinners
20 beef dinners

c) The maximum earnings are estimated to be ...

($12)(40) +($16)(20) = $800

Anestetic [448]

Answer:

47.37%

Explanation:

The capital budget is $625,000 out of which 40% is equity and the rest 60% is debt. The company forecasts the net income for the year to be $475,000. Grandin Inc. follows residual dividend policy and pays out all the residual income to its shareholders as dividend.

The portion of equity in the capital budget is $625,000 * 40% = $250,000

The net income potion which will be attributable to equity shareholders is

$250,000 / $475,000 = 47.37%
