Answer:
The answer to this question is given below in the explanation section.
Explanation:
A <u> </u><u>logic </u><u> </u>error occurs when a program runs accurately, but yields the wrong result. Therefore, it is difficult to detect. However, a program can detect <u> </u><u>syntax </u><u> </u>errors rapidly, because they occur in the structure of programming code during the compilation stage.
Answer:
- Code is in JAVA language. As there is no user input the logic is straightforward.
- Below is the code along with a detailed explanation of the logic.
- The class name is Print main save as file as the main class.
Explanation:
Program:-
public class Main{
public static void main(String args[]){
/* There are two for loops...
* First for loop runs from i=1 to i=9
* Second for loop runs from j=1 to j=i.
*
*/
for(int i=1;i<=9;i++){
for(int j=1;j<=i;j++){ // j loop runs from j=1 to j=i
/*Prints I and j next to each other*/
System.out.println(i+""+j);
}//for loop of j ends here
}// for loop of I ends here
}
}
Answer:
a. count of observations that meet a condition (counts), total number of observations (nobs), Hypothesized value of population proportion (value).
Explanation:
In other to use the proportion_ztest method, the need to make import from the statsmodel module ; statsmodels.stats.proportion.proportions_ztest ; this will allow use use the Z test for proportion and once this method is called it will require the following arguments (count, nobs, value=None, alternative='two-sided', prop_var=False)
Where;
nobs = number of observations
count = number of successes in the nobs trial or the number of successes for each independent sample.
Value = hypothesized value of the population proportion.
Enroll a student identified by her snum into the class named 'Introduction to Database Systems' is the following transactions, state the SQL isolation level you would use.
1. Enroll a student identified by her snum into the class named 'Introduction to Database Systems'.
<u>Explanation:</u>
Since enroll is unique in the university enrollment database schema and field name is SNUM and it is data type is an integer. To identify student class name and department name and name of student SNUM field is used for searching in university enrollment database schema. Enrollment changing is not possible of the student’s not possible or not good practices in university enrollment database schema.
If a query had been made class wise or department wise enrollment is played an important role.
For assign, a faculty is made on the class id or department id.
