What is the output of the following program?

Contact [7]

The question is poorly formatted:

#include <stdio.h>

int main() {

int arr [5] = {1, 2, 3, 4, 5};

arr [1] = 0;

arr [3] = 0;

for (int i = 0;i < 5; i+=1)

printf("%d", arr[i]);

return 0;

}

Answer:

The output is 10305

Explanation:

I'll start my explanation from the third line

This line declares and initializes integer array arr of 5 integer values

int arr [5] = {1, 2, 3, 4, 5};

This line sets the value of arr[1] to 0

arr [1] = 0;

At this point, the content of the array becomes arr [5] = {1, 0, 3, 4, 5};

This line sets the value of arr[3] to 0

arr [3] = 0;

At this point, the content of the array becomes arr [5] = {1, 0, 3, 0, 5};

The next two lines is an iteration;

The first line of the iteration iterates the value of i order from 0 to 4

for (int i = 0;i < 5; i+=1)

This line prints all elements of array arr from arr[0] to arr[4]

printf("%d", arr[i]);

So, the output will be 10305

rewona [7]

Answer:

Correct the data she entered, and the software will adjust the graph.

Explanation:

Software is used to work with ease and efficiency. If there is any mistake during data entry, we can easily change that particular data and make it correct. There is no need to delete whole data and re enter the data again. As most of the software are user friendly and have the option to edit the information that already has been entered.

In mentioned case, Kiara should edit the data, that has been entered incorrect. After the correction of data, the graph will be automatically updated with new values and she found correct graph.

Fifty-three percent of U.S households have a personal computer. In a random sample of 250 households, what is the probability th

aleksley [76]

Answer:

The correct Answer is 0.0571

Explanation:

53% of U.S. households have a PCs.

So, P(Having personal computer) = p = 0.53

Sample size(n) = 250

np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10

So, we can just estimate binomial distribution to normal distribution

Mean of proportion(p) = 0.53

Standard error of proportion(SE) = $\sqrt{\frac{p(1-p)}{n} }$ = $\sqrt{\frac{0.53(1-0.53)}{250} }$ = 0.0316

For x = 120, sample proportion(p) = $\frac{x}{n}$ = $\frac{120}{250}$ = 0.48

So, likelihood that fewer than 120 have a PC

= P(x < 120)

= P( p^ < 0.48 )

= P(z < $\frac{0.48-0.53}{0.0316}$ ) (z= $\frac{p^-p}{SE}$ )

= P(z < -1.58)

= 0.0571 ( From normal table )
