Answer:

Which line of code outputs the decimal portion of a float stored in the variable x?

print (x - int(x))

Three of the following values could be stored as strings. When would you NOT use a string command?

To store decimal values.

Consider the following code:

x = int(input("Enter a number: "))

print (x)

What happens if the user types in A?

This would cause an error: an integer variable cannot store a string.

Which of the following is NOT a data type in Python?

decimal

Which of the following numbers might this code generate: random.randint(1,9)?

When working with arrays, most programming languages perform ________, which means they do not allow programs to use invalid sub

Allisa [31]

Answer:

The answer is "Option 2"

Explanation:

In the given question the answer is "array bounds checking", It Checks the limits by providing a way, that Specifies whether a value is inside those limits has been used. It is a variable, that falls into a given class or function called as an array index of array, that's why all option are wrong, that is explained as follows:

In option 1, It uses provides security, that's why it is wrong.

In option 3, It works on the bits, that's why it is not correct.

In option 4, It uses two thing that is "array bound checks and sub-script of bond", that's why it is wrong.

Answer:

The following are the answer to the given points:

Explanation:

In point (a):

Calculating the long-distance call cost:

$= 4 \times 5 \times 0.40 \\= 20 \times 0.40\\= 8$

Calculating the local call cost:

$= 10 \times 3 \times 0.05\\ = 30 \times 0.05\\= 1.5$

Calculating the overall cost of PSTN:

$= 25 + (4 \times 5 \times 0.40) + (10 \times 3 \times 0.05) + 2000 + 275 \\= 25 + 8 + 1.5 + 2000 + 275 \\= 2309.5$

In point (b):

Calculating the call rate per second and the average arrival rate:

$\to (\lambda) = 0.2$

The call average length:

$\to (T_s) = - 8 \\\\ = (8 \times 60) \ seconds \\\\ = 480 \ seconds$

The complete agent number:

$\to (m) = 9$

The strength of traffic:

$\to u = \lambda \times T_s \\\\ = (0.2 \times 480) \\\\ = 96$

The occupancy of the agent:

$\to p = \frac{u}{m} \\\\$

$= \frac{96}{9} \\ \\= 10.66$

Calculation of obtained:

$= \frac{(\frac{um}{m!})}{(\frac{um}{m!})} + (1-p) \sum {m-1} _{k=0} \ \frac{uk}{k!}$

We get = 0.329 to substitute values.

In point (c):

The rate of blocking = $5 \%$

average call time $(T_s) = 480 \ seconds$

$= 0.05 \times 480 \ seconds \\ = 24 \ second$

In point (d):

Calculating the number of link, which is required:

$= \frac{275}{5} \\\\ =55$

In point (e):

Calculating the Line Number:

$= \frac{275}{5} \\\\ =55$

PSTN line number:

$= (\frac{2000}{55}) \\\\ = 36.3636\\\\= 37$

In point (f):

The gross design expense = $ 2309. 5

Suppose a switch is built using a computer work station and that it can forward packets at a rate of 500,000 packets per second,

Marina86 [1]

Answer:

When the transmission exceeds 667 packets

Explanation:

In computer networking, a packet is a chunk of data transmitted across the network. The packet size of an Ethernet network is 1.5kilobytes, while the packet size of an IP packet payload is 64 kilobytes.

A switch is a physical network device that connects nodes or workstations while communicating the packets (or frames). The I/O bus size bandwidth is 1Gbps which allows approximately 667 packets. Once this packet size is crossed, the bus becomes a limiting factor or bottle neck.

When you block a number can they still text??

noname [10]

When a blocked number tries to send you a text message, it won’t go through, and they will likely never see the “delivered” note. On your end, you’ll see nothing at all. As far as phone calls are concerned, a blocked call goes directly to voice mail. On your end, you’ll get a special “blocked messages” folder in your voice mail inbox if they leave a message, but you won’t get a notification they called.
