Assume that the population of Mexico is 114 million and that the population increases 1.01 percent annually. Assume that the pop

AfilCa [17]

Answer:

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variables

double mexico = 114;

double usa = 312;

double mexicoRate = .0101;

double usaRate = .0015;

// calculate population after every year until mexico population exceed the usa populationn

while (usa>mexico)

{

// print the population

cout<<"Mexico's population ::"<<mexico<<" million."<<endl;

cout<<"USA's population ::"<<usa<<" million."<<endl;

// update the population

mexico+=mexico*mexicoRate;

usa-=usa*usaRate;

}

return 0;

}

Explanation:

Declare and initialize mexico and usa with their initial population.Also declare and initial their increase and decrease rate.Find the population of both the country each year until mexico population exceeds the usa population.

Output:

Mexico's population ::114 million.

USA's population ::312 million.

Mexico's population ::115.151 million.

USA's population ::311.532 million.

.

Mexico's population ::270.546million.

USA's population ::274.213 million.

Mexico's population ::273.278million.

USA's population ::273.802 million.

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
