Absolute reference is used especially to keep the value or content of a column or row constant.

Cell referencing is one common and important concept in spreadsheets. A cell reference or cell address is a value, mostly alphanumeric, used to identify a specific cell or cell range in a worksheet.

In spreadsheets such as that of Microsoft - excel - there are basically two types of referencing.

i. relative referencing

ii. absolute referencing

iii. mixed referencing

Relative reference is the default cell reference. When a relative reference is copied and pasted across multiple cells, it changes depending on its relative position. This type of reference is especially useful when there is a need to apply same formula across multiple rows or columns.

Absolute reference, on the other hand, will not change even though it is copied across multiple cells. It is used especially to keep the value or content of a column or row constant.

Mixed reference is a hybrid of the relative and absolute references.

Answer:

# the dog dataframe has been loaded as mpr

# select the dogs where Age is greater than 2

greater_than_2 = mpr [mpr. age > 2]

print(greater_than_2)

# select the dogs whose status is equal to 'still missing'

still_missing = mpr[mpr. status == 'Still Missing']

print(still_missing)

# select all dogs whose dog breed is not equal to Poodle

not_poodle = mpr [mpr.breed != 'Poodle']

print(not_poodle)

Answer go to y o u t u b e type in volleyball_chan hit the sub button

Explanation:

Answer:

#include <iostream>

#include <string>

#include <regex>

using namespace std;

int main()

{

   cout << "Enter a 5-digit number: ";

   string number;

   cin >> number;

   bool valid = regex_search(number, regex("^\\d{4}[02468]$"));

   if (valid) {

       valid = stoi(number.substr(0, 1)) + stoi(number.substr(1, 1))  

           < stoi(number.substr(3, 1)) + stoi(number.substr(4, 1));

   }

   cout << number << (valid ? " is valid" : " is invalid");

}

Explanation:

Regular expressions can do all of your checking except for the sum of digits check. The checks are i.m.o. easiest if you don't treat the input as a number, but as a string with digits in it.

The regex means:

^ start of string

\d{4} exactly 4 digits

[02468] one of 0, 2, 4, 6 or 8 (this is what makes it even)

$ end of string

Answer:

Primary memory is computer memory that a processor or computer accesses first or directly. It allows a processor to access running execution applications and services that are temporarily stored in a specific memory location. Primary memory is also known as primary storage or main memory.

Explanation:

Answer:

Explanation:

The best way to do this would be to use the following line of code

clear: left;

This would make sure that there are no floating elements (li's in this scenario) on the left side of each element. Which in this navigation list would be each individual element, causing it to move each element underneath the previous element. Therefore the entire CSS code would be

.horizontal li {

   display: block;

   width: 12.5%;

   float: left;

   clear: left;

   }

An example can be seen in the attached picture below.

Answer:

a) 15.24 kbps

b) 762 bits

Explanation:

Using little law

a) Determine the average arrival rate (  λ  ) in units of packets/s

λ  = r / Tr  --- 1

where ; r = 1000 bits , Tr = Tw + Ts = 0.05 + (( 1000 / (64 * 1000 ))  = 0.0656

back to equation 1

λ = 1000 / 0.0656 = 15243.9 = 15.24 kbps

b) Determine average number of packets w to be served

w =  λ * Tw =  15243.9 * 0.05 = 762.195 ≈ 762 bits

Answer:

B. The item has been selected

Answer:

C

Explanation:

When an item is unavailable, usually referring to the Technology field, it is gray. Gray items are things that are not created anymore, sold out or not enough supply. The color gray is usually used to symbol something bad, and not having a product is considered bad. Using our background knowledge, we can concude that the answer is option C.

A computer monitor is an electronic device that shows pictures for computers. Monitors often look similar to televisions. The main difference between a monitor and a television is that a monitor does not have a television tuner to change channels. Monitors often have higher display resolution than televisions.

A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing.

Speakers receive audio input from the computer's sound card and produce audio output in the form of sound waves. Most computer speakers are active speakers, meaning they have an internal amplifier which allows you to increase the volume, or amplitude, of the sound.

Replace the comment with:

maxSum =FindMax(numA,numB)+FindMax(numY,numZ);

Explanation:

Required

The statement to add up the two maximum from the functions

To do this, we have to call FindMax for both arguments i.e.

FindMax(numA,numB) and FindMax(numY,numZ) respectively

Next, use the + sign to add up the returned value.

So, the complete statement is:

maxSum =FindMax(numA,numB)+FindMax(numY,numZ);

See attachment for complete program

Answer:

The program in python is as follows:

n = int(input("n: "))

sum = 0

for i in range(2,n+1):

   if i%2 == 0:

       sum+=i

print(sum)

Explanation:

This gets input n

n = int(input("n: "))

This initializes sum to 0

sum = 0

This iterates through n

for i in range(2,n+1):

This checks if current digit is even

   if i%2 == 0:

If yes, take the sum of the digit

       sum+=i

Print the calculated even sum

print(sum)

Answer:

e.

balance = balance + amount;

return balance;

Explanation:

Required

Code to update account balance and return the updated balance

The code that does this task is (e).

Assume the following:

[tex]balance = 5000; amount = 2000;[/tex]

So, code (e) is as follows:

balance = balance + amount; [tex]\to[/tex]

[tex]balance = 5000 + 2000[/tex] [tex]\to[/tex]

[tex]balance = 7000[/tex]

Here, the updated value of balance is 7000

So: return balance

will return 7000 as the updated account balance

Following are the response to the given question:

Explanation:

The glamorous objective is to examine the items (as being the most valuable and "cheapest" items are chosen) while no item is selectable - in other words, the loading can be reached.

Assume that such a strategy also isn't optimum, this is that there is the set of items not including one of the selfish strategy items (say, i-th item), but instead a heavy, less valuable item j, with j > i and is optimal.

As [tex]W_i < w_j[/tex], the i-th item may be substituted by the j-th item, as well as the overall load is still sustainable. Moreover, because [tex]v_i>v_j[/tex] and this strategy is better, our total profit has dropped. Contradiction.

Answer:

war driving.

Explanation:

Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, etc.

Generally, the two (2) essential privacy concerns in the field of cybersecurity are knowing how personal data are collected and essentially how they're used by the beneficiaries or end users.

War driving can be defined as a form of cyber attack which typically involves having eavesdroppers in a moving vehicle drive by buildings or park outside so as to avail them the opportunity of intercepting a wireless network traffic using a smartphone or laptop computer and illegitimately obtain sensitive user informations for further unauthorized use or to perform other fraudulent activities.

Answer:

The valid operations are:

*q = *(&a[0]);  and q = &(*p);

Explanation:

Given

The above declarations

Required

The valid operations

*q = *(&a[0]);  and q = &(*p); are valid assignment operations.

However, q = &&a[0]; q = &&a; are invalid because:

The assignment operations intend to implicitly cast the char array a to pointer q. C++ does not allow such operation.

Hence, *q = *(&a[0]);  and q = &(*p); are valid

Another way to know the valid operations is to run the program and look out for the syntax errors thrown by the C++ compiler
