Answer:

However, if the dataset is relatively small, every data point counts. In these situations, a missing data point means loss of valuable information. In any case, generally missing data creates imbalanced observations, cause biased estimates, and in extreme cases, can even lead to invalid conclusions.

Answer:

1. Option (a) is the correct answer. "Place a firewall between the Internet and your Web server".

2. Option (e) is the correct answer. "Require encryption for all traffic flowing into and out from the Ken 7 Windows environment".

3. Option (d) is the correct answer. "Implement Kerberos authentication for all internal servers".

4. The correct answer is option (g) "Require all personnel attend a lunch and learn session on updated network security policies".

5. Option (c) is the correct answer. "Enforce password complexity".

Explanation:

1. Users who tried to use ken 7 network resources for social media access will not be enable to do so.

2. Encryption for inflow and outflow of traffic from Ken 7 windows environment will monitor any personal devices which is connected to Ken 7 windows network.

3. The implementation of Kerberos authentication will deny anonymous users access to protected resources in Ken 7 infrastructure.

4.All personnel will be taught the network policies to avoid sending report to unsecured printers.

5. The more complex passwords are, the more secured the server will be. A complex password should be enforce for network security.

As data travels further over a wavelength or frequency, what goes down?

LUCKY_DIMON [66]

As data travels further over a wavelength or frequency, the radiation type goes down.

<h3>What is an electromagnetic spectrum?</h3>

An electromagnetic spectrum can be defined as a range of frequencies and wavelengths into which an electromagnetic wave is distributed into.

In Science, the electromagnetic spectrum consist of the following types of energy from highest to lowest frequency and shortest to longest wavelength:

Gamma rays

X-rays

Ultraviolet radiation

Visible light

Infrared radiation

Microwaves

Radio waves

In this context, we can infer and logically deduce that as data travels further over a wavelength or frequency within the electromagnetic spectrum, the radiation type goes down.

Write a function called countstuff () that takes as a parameter a character array, and returns an int. The prototype must be:

PSYCHO15rus [73]

Answer:

Please kindly go to the explanation part.

Explanation:

The required function is written in Raw code below.

Function:

#include<stdio.h>

#include<ctype.h> //including required libraries

int countstuff(char s[]){ //Function countstuff

int cntUp=0,cntLow =0,cntDigits = 0,i=0,value; //declaring required variables

for(i=0;s[i]!='\0';i++){ //loop to iterate over the characters of string

if(isupper(s[i])){

cntUp++; //incrementing count of uppercase if it is uppercase character

}

else if(islower(s[i])){

cntLow++; //incrementing count of lowercase if it is lowercase character

}

else if(isdigit(s[i])){

cntDigits++; //incrementing count of digits if it is digit

}

value = cntUp*1000000 + cntLow*1000 + cntDigits; //counting value using formula given in question

return value; //returning the value

}

void main(){

char string[1000]; //declaring required variables

int value;

printf("Enter a String:");

scanf("%[^\n]s",string); //taking string as input

value = countstuff(string); //calling function

printf("The Value is : %d\n",value); //printing result

}

write a java program that prompts the user to enter scores (each number an integer from 0 to 10) and prints the following output

Vladimir [108]

Answer:

Explanation:

The following is written in Java. It continues asking the user for inputs until they enter a -1. Then it saves all the values into an array and calculates the number of values entered, the highest, and lowest, and prints all the variables to the screen. The code was tested and the output can be seen in the attached image below.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Scanner;

class Brainly {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

int count = 0;

int highest, lowest;

ArrayList<Integer> myArr = new ArrayList<>();

while (true) {

System.out.println("Enter a number [0-10] or -1 to exit");

int num = in.nextInt();

if (num != -1) {

if ((num >= 0) && (num <= 10)) {

count+= 1;

myArr.add(num);

} else {

System.out.println("Wrong Value");

}

} else {

break;

}

if (myArr.size() > 3) {

highest = myArr.get(0);

lowest = myArr.get(0);

for (int x: myArr) {

if (x > highest) {

highest = x;

}

if (x < lowest) {

lowest = x;

}

System.out.println("Number of Elements: " + count);

System.out.println("Highest: " + highest);

System.out.println("Lowest : " + lowest);

} else {

System.out.println("Number of Elements: " + count);

System.out.println("No Highest or Lowest Elements");

}
