A group consists of 10 kids and 2 adults. On a hike, they must form a line with an adult at the front and an adult at the back.
blsea [12.9K]

Answer:

b. 2.9!

Explanation:

There are is a mistake in the question.

Suppose the group consist of 10 kids and 2 adults, the number of ways in which they can form the line is:

= 2! 10!

= 2× 1× 10!

= 2.10!

But since that is not in the given option.

Let assume that the group consists of 9 kids and 2 adults, the number of ways in which they can form the line is:

No of ways the kids can be permutated =  9 ways

No of ways the adult can be permutated  = two ways.

Thus; the number of ways in which they can form the line = 2! 9!

= 2 × 1× 9!

= 2.9!

explain why the database system would not allow a tuple to be inserted into the database through this view
Andrej [43]
For the view of Exercise 4.18, explain why the database system would not allow a tuple to be inserted into the database through this view.
For reference
For the database of Figure 4.12, write a query to find the ID of each employee with no manager. Note that an employee may simply have no manager listed or may have a null manager. Write your query using an outer join and then write it again using no outer join at all.
OUTER JOIN
select e.ID from employee e left outer join manages m on e.ID = m.ID
where m.manager_id is null;
NO OUTER
select e.ID from employee e where e.ID not in (select m.ID from manages m) or e.ID in (select m.ID from manages m where m.manager_id is null);
