company gives the following discount if you purchase a large amount of supply. Units Bought Discount 10 - 19 20% 20 - 49 30% 50

ratelena [41]

Answer:

In Python:

order = int(input("Order: "))

discount = 0

if(order >= 10 and order <20):

discount = 0.20

elif(order >= 20 and order <50):

discount = 0.30

elif(order >= 50 and order <100):

discount = 0.35

elif(order >= 100):

discount = 0.40

price = order * 4.1

discount = discount * price

print("With your order of "+str(order)+" items, the total value will be $"+str(round(price,2))+" with a discount of $"+str(round(discount,2))+" for a final price of $"+str(round((price-discount),2)))

Explanation:

This prompts the user for number of orders

order = int(input("Order: "))

This initializes the discount to 0

discount = 0

For orders between 10 and 19 (inclusive)

if(order >= 10 and order <20):

-----------discount is 20%

discount = 0.20

For orders between 20 and 49 (inclusive)

elif(order >= 20 and order <50):

-----------discount is 30%

discount = 0.30

For orders between 50 and 99 (inclusive)

elif(order >= 50 and order <100):

-----------discount is 35%

discount = 0.35

For orders greater than 99

elif(order >= 100):

-----------discount is 40%

discount = 0.40

This calculates the total price

price = order * 4.1

This calculates the pre discount

discount = discount * price

This prints the report

print("With your order of "+str(order)+" items, the total value will be $"+str(round(price,2))+" with a discount of $"+str(round(discount,2))+" for a final price of $"+str(round((price-discount),2)))

The Knowledge Consistency Checker (KCC) ensures the maximum number of hops between any two domain controllers does not exceed wh

Katarina [22]

Answer:

Three (3)

Explanation:

Explanation of the three basic terms here - Knowledge consistency checker, hops and domain controller - will give a clearer answer and explanation to the question as follows;

Domain controller : is a server controller that gives access or controls to users on computer networks by first responding to their authentication requests and verifying those users. In other words, a domain controller is a network security manager.

Hop : A hop is simply the passage of data packets from one network to another. As a packet moves from its source to destination, it moves from router to router. The number of such routers that the packet passes through is called a hop.

The Knowledge Consistency Checker (KCC) : It is the job of the KCC to ensure that these domain controllers participate in the replication promptly and orderly. Replication means copying data from one location to another (within a network or among networks). The KCC ensures that the maximum number of hops permitted is does not exceed 3. i.e no domain controller is more than 3 hops from any other domain controller within a network.

Note: Replication is of two types - intrasite (among all domain controllers within a site) and intersite (among all domain controllers in different sites), and the KCC can manage both type of replication. Also, by default, at every 15 minutes interval, a domain controller generates a replication topology (a logical map that dictates the domain controllers that will replicate with each other).

Hope this helps!

Answer the following questions:

victus00 [196]

Answer:

The answer to the following questions can be given as:

Question: 1

value of foo is = 1020

Question: 2

Output of the code is = false

Question: 3

function add(a, b)

{

return a && b ? a + b : function (c) { return a + c; };

}

var a=add(2,5);

var x=add(2)(5);

print(a);

print(x);

output:

Question: 4

"goh angasal a m'i"

Question: 5

In this we check that if in the window a foo function exists. otherwise we set windows.foo to bar.

Question: 6

first alert shows the value "Hello World";

second alert shows value ReferenceError, In this bar not defined.

Question: 7

The value of foo.length is 2

Question: 8

The value of foo.x is undefined

Question: 9

Function print = "one", "three", "two" .

Question :10

It is difficult to define because doSomethingElse() function is not defined.

Explanation:

In question 1 the value of the foo variable is 1020 because we perform the string concat operation.

In question 2 Output of the code is false because float value keeps in binary and when we convert 0.1 or 0.2 to binary so it is not the same.

In question 3 the output of both functions is 7.

In question 4 the output is goh angasal a m'i because In this code we use the reverse() function, split() function and join() function. Reverse function reverses the value. split function splits the value and join function join all the value of the string in a line.

In question 5 we check the value.

In question 6, the first output is Hello World and second is ReferenceError.

In question 7, the value of foo.length is 2 because this foo array we insert only 2 values.

In question 8, the value of foo.x is undefined because in the variable we reset the value of foo all together, so foo.x value is undefined.

In the question 9 function print "one",

"three",

"two" because In the function first, we print the message that is "one" then we define a function in this function we print the value

"two" but before creating object we call the "three" so the print value is "one",

"three",

"two".

In question 10 function, the output of this function is undefined.
