taurus [48]

Answer:

"The novels"

Explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

Based on the sentence, we can see it is mentioning an object that belongs to Willa Catha. Unfortunately, all of them can be possible correct answers based on that information so we need to check which ones make the sentence factually and grammatically correct.

Therefore the only answer that makes this sentence both factually and grammatically correct is the last answer "The novels".

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

________ is used for supervisory messages at the internet protocol layer.

Natalija [7]

"ICMP" is used for supervisory messages at the internet protocol layer.
ICMP stands for Internet Control Message Protocol and it refers to a supporting protocol in the Internet protocol suite. It is utilized by network devices which includes routers and these are used to send error messages and operational data showing, for instance, that asked for service which isn't accessible or that a host or switch couldn't be come to.

Recall the problem of finding the number of inversions. As in the text, we are given a sequence of n numbers a1, . . . , an, whi

Kay [80]

Answer:

The algorithm is very similar to the algorithm of counting inversions. The only change is that here we separate the counting of significant inversions from the merge-sort process.

Algorithm:

Let A = (a1, a2, . . . , an).

Function CountSigInv(A[1...n])

if n = 1 return 0; //base case

Let L := A[1...floor(n/2)]; // Get the first half of A

Let R := A[floor(n/2)+1...n]; // Get the second half of A

//Recurse on L. Return B, the sorted L,

//and x, the number of significant inversions in $L$

Let B, x := CountSigInv(L);

Let C, y := CountSigInv(R); //Do the counting of significant split inversions

Let i := 1;

Let j := 1;

Let z := 0;

// to count the number of significant split inversions while(i <= length(B) and j <= length(C)) if(B[i] > 2*C[j]) z += length(B)-i+1; j += 1; else i += 1;

//the normal merge-sort process i := 1; j := 1;

//the sorted A to be output Let D[1...n] be an array of length n, and every entry is initialized with 0; for k = 1 to n if B[i] < C[j] D[k] = B[i]; i += 1; else D[k] = C[j]; j += 1; return D, (x + y + z);

Runtime Analysis: At each level, both the counting of significant split inversions and the normal merge-sort process take O(n) time, because we take a linear scan in both cases. Also, at each level, we break the problem into two subproblems and the size of each subproblem is n/2. Hence, the recurrence relation is T(n) = 2T(n/2) + O(n). So in total, the time complexity is O(n log n).

Which types of attacks are thwarted by complex passwords that are combinations of upper and lower case letters, numbers, and spe

lesantik [10]

The types of attacks that are known to be thwarted by complex passwords that are combinations of upper and lower case letters, numbers, and special characters are said to be Brute Force Attacks.

What is Brute Force Attacks?

This is known to be an attack that is said to be a very crude type of attack and it is often seen as a brute-force attack.

Note that is one that does not depend on lists of passwords, but it is one that often tries all the very possible combinations of permitted character types.

Hence, this type of attack was known to be historically seen as ineffective, and it is said to be The types of attacks that are known to be thwarted by complex passwords that are combinations of upper and lower case letters, numbers, and special characters are said to be Brute Force Attacks.

Which of the following can be used to locate data in a particular column?

dangina [55]

Answer:

A. VLOOKUP

Explanation:

VLOOKUP is an Excel function to look up data in a table organized vertically. VLOOKUP supports approximate and exact matching, and wildcards (* ?) for partial matches. Lookup values must appear in the first column of the table passed into VLOOKUP.

Purpose

Lookup a value in a table by matching on the first column

Return value

The matched value from a table.

Syntax

=VLOOKUP (value, table, col_index, [range_lookup])

Arguments

value - The value to look for in the first column of a table.

table - The table from which to retrieve a value.

col_index - The column in the table from which to retrieve a value.

range_lookup - [optional] TRUE = approximate match (default). FALSE = exact match.
