Suppose that each country completely specializes in the production of the good in which it has a comparative advantage, producing only that good. Inthis case, the country that produces rye will produce million bushels per week, and the country that produces jeans will produce

million pairs per week.

Answer 1
Answer:

Answer:

In  this case, the country that produces rye will produce 24 million bushels per week, and the country that produces jeans will produce 64  million pairs per week.

Explanation:

Total labor hour = 4 million hour

Number of bushes produce in 1 hour = 6

⇒total bushes produce = 6*4 = 24 million

∴ we get

The country that produces rye will produce 24 million bushels per week

Now,

Total labor hour = 4 million hour

Number of pairs produce in 1 hour = 16

⇒total bushes produce = 16*4 = 64 million

∴ we get

The country that produces jeans will produce 64  million pairs per week.

Subtract (100000)2 from (111)2 using 1s and 2s complement method of subtraction​

Answers

Answer:

-11001

Explanation:

The following steps are performed in order to perform subtraction of the given binary numbers:

Step 1:

Find 2’s complement of the subtrahend. The subtrahend here is 100000

100000

First take 1's complement of 100000

1's complement is taken by inverting 100000

1's complement of 100000 = 011111

Now takes 2's complement by adding 1 to the result of 1's complement:

011111 + 1 = 100000

2's complement of 100000 = 100000

Step 2:

Add the 2's complement of the subtrahend to the minuend.

The number of bits in the minuend is less than that of subtrahend. Make the number of bits in the minuend equal to that of subtrahend by placing 0s in before minuend. So the minuend 111 becomes:

000111

Now add the 2's complement of 100000 to 000111

   0 0 0 1  1  1

+   1 0 0 0 0 0

    1 0 0 1  1  1

The result of the addition is :

 1 0 0 1  1  1

Step 3:

Since there is no carry over the next step is to take 2's complement of the sum and place negative sign with the result as the result is negative.

sum =   1 0 0 1  1  1

2's complement of sum:

First take 1's complement of 1 0 0 1  1  1

1's complement is taken by inverting 1 0 0 1  1  1

1's complement of 1 0 0 1  1  1 = 0 1 1 0 0 0

Now takes 2's complement by adding 1 to the result of 1's complement:

0 1 1 0 0 0 + 1 = 0 1 1 0 0 1

Now place the minus sign with the result of 2's complement:

- 0 1 1 0 0 1

Hence the subtraction of two binary numbers (100000)₂ and (111)₂  is

(-011001)₂

This can also be written as:

(-11001)₂

"Write an SQL query that displays the Ssn and Last name of all employees who is a supervisor of a Department Manager"

Answers

Answer:

SELECT Ssn,

             Last_name

 FROM employees

WHERE position = supervisor;

Explanation:

SELECT is an SQL query statement that is used to initiate the display of wanted variables.

The names of the variables often succeed the SELECT statement and they are separated by commas.

FROM is an SQL query statement that indicates the table fro which the selected variables be displayed.

WHERE is used to filter your search and return only rows that meet the criteria.

; signifies the end of a query and calls for an execution.

Answers

Answer:

Must use mutators to initialize class data.

May use assignment statements to initialize class data.

Explanation:

These are the two characteristics that are present in constructors. A constructor is an instance method of a class or structure that creates an object of the class to which it belongs. This is mostly used in object-oriented programming. These constructors usually have the same name as the actual class, and can be used in order to set the values of the members of an object.

Obtain the 9’s complement of the following eight-digit decimal numbers:12349876

89009951

Answers

Answer:

87650123

10990048

Explanation:

We have to find the 9's compliment of the given numbers

Now for the given data

a) given = 12349876

9's complement of the given number is calculated as:

99999999 - 12349876

or

= 87650123

b)  given number = 89009951

9's complement for the given number 89009951  is calculated as:

99999999 - 89009951

or

= 10990048
