A chemical company alleged that the average weight of the bag of chemical is 30kgs. with a standard deviation of 1.1 kgs. A sample of 26 bags was taken and revealed a mean weight of 28.9 kgs. Shall we accept the allegation of the chemical company? Use .01 level of significance
Find the initial speed which a projectile must be subjected to give it a maximum horizontal range of 490m. Assume the acceleration due to gravity as g=10m/s
The reaction of diatomic fluorine gas (F2) with compound X yields a single product, compound Y. The mass percent composition of the product, compound Y is 61.7% F2 and 38.3% Cl. What is the probable empirical formula for product Y? What is a probable empirical formula for compound X?
Instructions:
- In the code editor, you are provided with an array of characters (or a string).
- Your task is to ask the user for an integer input which represents the index and then print out the character of the string found at that index.
Code:
#include <iostream>
using namespace std;
int main() {
char array[100] ="supercalifragilisticexpialidocious";
return 0;
}
Instructions:
- Declare and define hasConsonant() function with he following details: int return type name hasConsonant parameter char
- Return value - 1if there is atleast 1 consonant and 0 if there is none. Include Both capital and small letters when checking
Code:
#include <iostream>
using namespace std;
// TODO: Declare the hasConsonant() function here
int hasConsonant(int code)
int main(void) {
char code[100];
cout << "Enter the code: ";
cin >> code;
int result = hasConsonant(code);
if(result == 1) {
cout << "ALERT! There is a consonant in the code!";
} else if(result == 0) {
cout << "There is no consonant in the code. Situation is under control!";
}
return 0;
}
// TODO: Define the hasConsonant() function here
