) Perform error checking for the data point entries. If any of the following errors occurs, output the appropriate error message

emmainna [20.7K]

Answer:

In Python:

entry = input("Sentence: ")

while True:

if entry.count(",") == 0:

print("Error: No comma in string")

entry = input("Sentence: ")

elif entry.count(",") > 1:

print("Error: Too many comma in input")

entry = input("Sentence: ")

else:

ind = entry.index(',')+1

if entry[ind].isnumeric() == False:

print("Comma not followed by an integer")

entry = input("Sentence: ")

else:

break

print("Valid Input")

Explanation:

This prompts the user for a sentence

entry = input("Sentence: ")

The following loop is repeated until the user enters a valid entry

while True:

This is executed if the number of commas is 0

if entry.count(",") == 0:

print("Error: No comma in string")

entry = input("Sentence: ")

This is executed if the number of commas is more than 1

elif entry.count(",") > 1:

print("Error: Too many comma in input")

entry = input("Sentence: ")

This is executed if the number of commas is 1

else:

This calculates the next index after the comma

ind = entry.index(',')+1

This checks if the character after the comma is a number

if entry[ind].isnumeric() == False:

If it is not a number, the print statement is executed

print("Comma not followed by an integer")

entry = input("Sentence: ")

If otherwise, the loop is exited

else:

break

This prints valid input, when the user enters a valid string

print("Valid Input")

Note that: entry = input("Sentence: ") is used to get input

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

Trava [24]

Answer:

Satyajit Ray (1921–1992), a Bengali film director from India, is well known for his contributions to Bengali literature. He created two of the most famous characters in Feluda the sleuth, and Professor Shonku the scientist. He wrote several short novels and stories in addition to those based on these two characters. His fiction was targeted mainly at younger readers (mostly teenagers) , though it became popular among children and adults alike.

Ray during recording of his film Pather Panchali

Most of his novels and stories in Bengali have been published by Ananda Publishers, Kolkata; and most of his screenplays have been published in Bengali in the literary journal Ekshan, edited by his close friend Nirmalya Acharya. During the mid-1990s, Ray's film essays and an anthology of short stories were also published in the West. Many of the stories have been translated into English and published.
