Which is a safe Internet behavior?

Write a method body for the static method isDivisibleBy5 shown below. The only NaturalNumber methods you are allowed to use are

raketka [301]

Answer:

public static boolean isDivisibleBy5(int number) {

boolean isTrue = true;

if (number % 5 == 0)

isTrue = true;

else

isTrue = false;

return isTrue;

}

Explanation:

- Create a method called isDivisibleBy5 that takes one parameter, an integer number

- Inside the method, create a boolean variable, isTrue, that will be used to store the result

- Check if the number is divisible by 5, using the module operator. If it is, set the isTrue as true. Otherwise, set the isTrue as false

- Return the isTrue

Define a function below called average_strings. The function takes one argument: a list of strings. Complete the function so tha

tester [92]

Answer:

def average_strings(lst):

total_length = 0

avg = 0

for s in lst:

total_length += len(s)

avg = total_length/len(lst)

return avg

Explanation:

Create a function called average_strings that takes one parameter, lst

Initialize the total length and avg variables

Create a for loop that iterates through the lst. Get each string's length and put it to the total length

When the loop is done, calculate the average, divide total length by length of the lst

Return the average

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
