Oxnard Casualty wants to ensure that their e-mail server has 99.98 percent reliability. They will use several independent server

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

A Python data model defining the state of a game for Tic-Tac-Toe. You must fully describe the notion of a state of the game, lim

Artist 52 [7]

Answer:

Check the explanation

Explanation:

Here in this game of Tic-Tac-Toe, it is using the TPGE engine which is a Tiny Python Game Engine. Let's talk about its functions like:-

def image_type(img): In this function, it is simply taking image as a parameter and returning its object type like DISC if the image is in graphical form, TEXT if it is a string, and LINE if it is other than the mentioned object.

def convert_image(img): In this function, it is simply taking image as a parameter and returning an equivalent graphical object as understood by John Zelle's. Mainly comparing for three things in this function and those are: if image equals to DISC then it is calling convert_circle(function), if image equals to LINE then it is calling convert_line(function), and if image equals to TEXT then it is calling convert_text(function),

def convert_circle(x): This function takes a list( a group of values) and makes a circle at the center of the window and the circle's radius is coming from the list.

convert_text, convert_line, convert_circle are only creating text, line, and circle and then returning it.

def graphical_elements(images): This function is taking image as a parameter and then extracting shape and color from the image and then calling convert_image(shape) and convert_type(shape) and it gives us graphic and kind respectively. Now it is checking whether kind equals to DISC If yes then filling color on the window else, setting the outline of the window

def run(): Here it is finally running the game with required parameters, the whole game is continously running under the while loop.

That's all

Write a loop that displays all possible combinations of two letters where the letters are 'a', or 'b', or 'c', or 'd', or 'e'. T

nikitadnepr [17]

Answer:

The program to this question can be given as:

Program:

#include <stdio.h> //include header file.

int main() //defining main method

{

char i,j; //defining variable

for (i='a'; i<='e'; i++) //outer loop for column

{

for (j='a'; j<='e'; j++) //inner loop for row

{

printf("%c%c\n",i,j); //print value

}

return 0;

}

Output:

image.

Explanation:

In the above C language program, firstly a header file is included. Then the main method is defined in this, a method contains a char variable that is "i and j". This variable is used in for loop, that is used to print the pattern.
To print the following patter two for loop is used the outer loop is used for print columns and the inner loop prints row.
In C language to print character, we use "%c" inside a loop print function is used, that prints characters.
