sattari [20]

Answer:

The smallest number of servers required is 3 servers

Explanation:

Given

$Reliability = 99.98\%$

$Individual Servers = 95\%$

Required

Minimum number of servers needed

Let p represent the probability that a server is reliable and the probability that it wont be reliable be represented with q

Such that

$p = 95\%\\$

It should be noted that probabilities always add up to 1;

So,

$p + q = 1$ '

Subtract p from both sides

$p - p + q = 1 - p$

$q = 1 - p$

Substitute $p = 95\%\\$

$q = 1 - 95\%$

Convert % to fraction

$q = 1 - \frac{95}{100}$

Convert fraction to decimal

$q = 1 - 0.95$

$q = 0.05$

------------------------------------------------------------------------------------------------

To get an expression for one server

The probabilities of 1 servers having 99.98% reliability is as follows;

$p = 99.98\%$

Recall that probabilities always add up to 1;

So,

$p + q = 1$

Subtract q from both sides

$p + q - q = 1 - q$

$p = 1 - q$

So,

$p = 1 - q = 99.98\%$

$1 - q = 99.98\%$

Let the number of servers be represented with n

The above expression becomes

$1 - q^n = 99.98\%$

Convert percent to fraction

$1 - q^n = \frac{9998}{10000}$

Convert fraction to decimal

$1 - q^n = 0.9998$

Add $q^n$ to both sides

$1 - q^n + q^n= 0.9998 + q^n$

$1 = 0.9998 + q^n$

Subtract 0.9998 from both sides

$1 - 0.9998 = 0.9998 - 0.9998 + q^n$

$1 - 0.9998 = q^n$

$0.0002 = q^n$

Recall that $q = 0.05$

So, the expression becomes

$0.0002 = 0.05^n$

Take Log of both sides

$Log(0.0002) = Log(0.05^n)$

From laws of logarithm $Loga^b = bLoga$

So,

$Log(0.0002) = Log(0.05^n)$ becomes

$Log(0.0002) = nLog(0.05)$

Divide both sides by $Log0.05$

$\frac{Log(0.0002)}{Log(0.05)} = \frac{nLog(0.05)}{Log(0.05)}$

$\frac{Log(0.0002)}{Log(0.05)} = n$

$n = \frac{Log(0.0002)}{Log(0.05)}$

$n = \frac{-3.69897000434}{-1.30102999566}$

$n = 2.84310893421$

$n = 3 (Approximated)$

Hence, the smallest number of servers required is 3 servers

IceJOKER [234]

Answer:

The answer is "Option A"

Explanation:

Escalation is the process of manipulating a bug, design failure in software program to obtain elevated access to the resources, which are usually shielded from the user, and wrong choices can be described as follows:

In option B, It is wrong because It can't provide any type of problem-solving.
In option C, It is wrong because it is a searching module.
In option D, It is wrong because it is used to verify the system.

This type of server spools documents and puts them in a queue.

Paraphin [41]

Print is the type of server that spools documents and puts them in a queue. Whenever you are printing multiple documents, it is the standard operation of the printer to prioritize those documents that came first and add to the queue the other documents waiting for printing.

write a C++ program that ask the user for the number of cookies eaten and display the calorie consumption

Artyom0805 [142]

Answer:

#include <iostream>

using namespace std;

int main()

{

int cookies;

cin >> cookies;

cout << "The calorie consumption is: " << cookies * 142 << endl;

return 0;

}

Explanation:

First line: include basic library of C++(input and output).

using namespace std;

Says to compiler we are using std.

int main() Main function

int cookies, cookies variable, of int type

cin >> cookies

get the number of the cookies from user

cout Print the text and calories(one cookie have 142 calories)

Have a nice day ;)

What does the % find

Sever21 [200]

Answer:

The FIND function returns the position (as a number) of one text string inside another. If there is more than one occurrence of the search string, FIND returns the position of the first occurrence. FIND does not support wildcards, and is always case-sensitive.
