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.

Donovan Company incurred the following costs while producing 500 units: direct materials $10 per unit, direct labour $25 per uni

Dafna1 [17]

Answer:

Option (D) is correct.

Explanation:

Unit product cost:

= Direct materials + Direct labor + Variable manufacturing overhead + Fixed manufacturing overhead

= $10 + $25 + $15 + $20

= $70

Operating income using absorption costing:

= (500 units × $100) - (500 units × $70) - (500 units × $5) - $7,500

= $50,000 - $35,000 - $2,500 - $7,500

= $5,000

A sporting goods manufacturer budgets production of 45,000 pairs of ski boots in the first quarter and 30,000 pairs in the secon

Alexandra [31]

Answer:

The budgeted materials need in kg. in the first quarter is 90,000 kg

Explanation:

For computing the budgeted material needed in the first quarter, first we have to calculate the consumption of first and second quarters separately, so that we can arrive to a solution.

The consumption of first quarter = Budgeted production × required kg

= 45,000 × 2

= 90,000 kg

The consumption of second quarter = Budgeted production × required kg

= 30,000 × 2

= 60,000 kg

The ending raw material inventory = 30% of second quarter

= 30% × 60,000

= 18,000 kg

Now put the formula to find out the purchase amount. The formula is shown below:

Raw material consumption = Opening raw material inventory + purchase of raw material - ending raw material inventory

where,

beginning inventory = 18,000 kg

90,000 = 18,000 + purchase - 18,000

So, the purchase is 90,000 kg

The question has asked the amount in kg so cost per kg is irrelevant.

Hence, the budgeted materials need in kg. in the first quarter is 90,000 kg

You recently purchased a stock that is expected to earn 10 percent in a booming economy, 4 percent in a normal economy, and lose

serious [3.7K]

Answer:

b. 3.70 percent

Explanation:

Expected rate of return of a stock, given probabilities, is calculated by summing up the product of probability of each state occurring by the expected return of the stock should that happen.

Expected rate of return = SUM (probability *return)

Boom;(probability* return) = (0.15* 0.10) = 0.015 or 1.5%

Normal ;(probability* return) = (0.70* 0.04) = 0.028 or 2.8%

Recession ; (probability* return) = (0.15* -0.04) = -0.006 or -0.6%

Next, sum up the expected return for each state of the economy to find the expected rate of return on this stock;

= 1.5% + 2.8% -0.6%

= 3.7%

Therefore, the correct answer is choice B.
