Constantine forms the following hypothesis. Let n be any non-negative number that meets the following condition: when n is divid

ed by 5, the remainder cannot equal 2. For such values of n, the quantity Q = 97 − 6n is a prime number so long as Q > 0. Which of the following values of n would provide a counterexample to this hypothesis? Indicate all such values.

Answer:

n=5

Explanation:

if n= 5

i.     n/5=5/5=1  so it divides completely the remainder is 0

ii.  97 - 6(5) = 97 - 30 = 67,   67 is a prime number.

Why are smartphones and tablets capable of handling rich content and interactivity?
NikAS [45]

Answer:

Explanation:

With the advance in technology, smartphones, and tablets are built to meet the ever-increasing needs of users.

Smartphones are mobile phones that also have internet connectivity, they can be used to make calls and perform many tasks just like the conventional desktop. Smartphones and tablets are indeed considered computers because they also process inputs in form of commands and they produce outputs.

Smartphones and tablets are capable of handling rich content and interactivity because:

1. Wireless synchronization with other devices: Just like desktops, laptops, they can interact with other devices, and can receive and also send information doesn't matter the distance.

2. They have Internet connectivity.

3. They have strong hardware, good storage capacity.

4. They have inbuilt software and are capable of accepting other software and programs.

5. They are built with an appealing user interface.

6. Just as computers have processors, smartphones and tablets also have processors to ensure their speed at processing informations.

Choose the correct sequence for classifier building from the following.
Alekssandra [29.7K]

Answer:

b

Explanation:

First, we need to initialize the classifier.

Then, we are required to train the classifier.

The next step is to predict the target.

And finally, we need to evaluate the classifier model.

You will find different algorithms for solving the classification problem. Some of them are like  decision tree classification  etc.

However, you need to know how these classifier works.  And its explained before:

You need  to initialize the classifier at first.

All kinds of classifiers in the scikit-learn make use of the method fit(x,y) for fitting the model or the training for the given training set in level y.

The predict(x) returns the y which is the predicted label.And this is prediction.

For evaluating the classifier model- the score(x,y) gives back the certain score for a mentioned test data x as well as the test label y.

You would like the user of a program to enter a customer’s last name. Write a statement thaUse the variables k, d, and s so that
mojhsa [17]

Answer:

1st question:

Use the variables k, d, and s so that they can read three different values from standard input an integer, a float, and a string respectively. On one line, print these variables in reverse order with exactly one space in between each. On a second line, print them in the original order with one space in between them.

Solution:

In Python:

k = input()  #prompts user to input value of k i.e. integer value

d = input()  #prompts user to input value of d i.e. float value

s = input()  #prompts user to input value of s i.e. a string

print (s, d, k)  #displays these variable values in reverse order

print (k, d, s)#displays these variable values in original order

In C++:

#include <iostream>    // to use input output functions

using namespace std;   //to identify objects like cin cout

int main() {    //start of main function

  int k;   //declare int type variable to store an integer value

  float d; //  declare float type variable to store a float value

  string s;   //  declare string type variable to store an integer value

  cin >> k >> d >> s;    //reads the value of k, d and s

  cout << s << " " << d << " " << k << endl;     //displays these variables values in reverse order

  cout << k << " " << d << " " << s << endl;   } // displays these variable values in original order

Explanation:

2nd question:

You would like the user of a program to enter a customer’s last name. Write a statement that asks user "Last Name:" and assigns input to a string variable called last_name.

Solution:

In Python:

last_name = input("Last Name:")

# input function is used to accept input from user and assign the input value to last_name variable

In C++:

string last_name;  //declares a string type variable named last_name

cout<<"Last Name: ";  // prompts user to enter last name by displaying this message Last Name:

cin>>last_name; // reads and assigns the input value to string variable last_name

The programs alongwith their outputs are attached.

Clunker Motors Inc. is recalling all vehicles from model years 1995-1998 and 2004-2006. A boolean variable named recalled has be
AlekseyPX

Answer:

boolean recalled;

((modelYear>=1995 && modelYear <=1998) || (modelYear>=2004 && modelYear<=2006)) ? recalled =true : recalled =false;

Explanation:

In the first line of the code we declare the variable of type boolean (values can only be true or false) then using the conditional expression operator (ternary operator) in place of an if statement, We state the conditions of the years that will return true and vice versa
