Answer:
Since we have the normally distributed data set of the 500 observations. hence, according to the formula there will be 95% of the total observation within two standard deviations from the mean.
Hence, no. of observations will be= 95% of 500= 95 *5 = 475
Also remember standard deviation is (Xi-X')²
The standard deviation is the measurement of the dispersion of the data set from the mean. And its quite important in Data science.
Explanation:
The answer is self explanatory.
Answer:
#include <iostream>
# include <conio.h>
using namespace std;
main()
{
int size;
cout<<"enter the size of array";
cin>>size;
int a[size],b[size];
for (int i=0;i<size;i++)
{
cout<<"enter the value in array a"<<i;
cin>>a[i];
}
for (int k=0;k<=size;k++)
{
{
if (a[k]%2==0)
{
for (int l=k; l<=size;l++)
{
a[l]=a[l+1];
}
size=size-1;
}
}
}
cout<<"\nArray list without even";
for(int j=0;j<size+1;j++)
{
cout<<"\n"<<a[j];
}
getch();
}
Explanation:
There is an array taken of variable size, the program has been written to delete the even elements from the array list. In this program "size " is the integer variable that is taken to mention the total elements of the array. Then enter the values on different index of array.
After that program find the even values and then delete these values. After the operation new array will be displayed on output.
Answer:
#include<iostream>
using namespace std;
//create the function which add two number
void addTwoNumber(int num_1,int num_2)
{
int result = num_1 + num_2; //adding
cout<<"The output is:"<<result<<endl; //display on the screen
}
//main function
int main(){
//calling the function
addTwoNumber(3,6);
return 0;
}
Explanation:
First, include the library iostream for using the input/output instructions.
then, create the function which adds two numbers. Its return type is void, it means the function return nothing and the function takes two integer parameters.
then, use the addition operation '+' in the programming to add the numbers and store the result in the variable and display the result.
create the main function for testing the function.
call the function with two arguments 3 and 6.
then, the program copies the argument value into the define function parameters and then the program start executing the function.
If you print the binary digits just like that, they'll be in the wrong order (lsb to msb). Below program uses recursion to print the digits msb to lsb. Just for fun.
void printBits(unsigned int n)
{
if (n > 1) {
printBits(n >> 1);
}
printf((n & 1) ? "1" : "0");
}
int main()
{
unsigned int number;
printf("Enter an integer number: ");
scanf_s("%d", &number);
printBits(number);
}
