Suppose that we pick the following three tuples from a legal instance of a relation S (S has 100 tuples in total). Relation S ha

AysviL [449]

Answer:

The correct answer is BC → A, A does not hold over S. we noticed the tuples (1 ,2 ,3 ) and (4 ,2 ,3) which can hold over S)

Explanation:

Solution

No, since in this case the instance of S is provided. so such particular dependencies are unable to breach through such instance, but unable to tell which the dependencies hold towards S.

A functional dependency holds towards only when a relation forms a statement regarding the complete allowed instances of relation.

a password to a certain database consists of digits that cannot be repeated. if the password is known to consist of at least 8 d

BaLLatris [955]

Answer:

$\frac{10!}{2}mins$

Explanation:

12 seconds to try one combination will be equivalent to $\frac{1}{12}\times 60 = \frac{1}{5} \ mins$

Password contain at least 8 digit i.e. password can contain 8, 9, 10 digit.

Password cannot contain more than 10 digit because it will give room for repetition which it is clearly stated that digit cannot be repeated.

Possible digit that can be used: 9,8,7,6,5,4,3,2,1,0.

Total number of passwords combination possible for each position in 8 digit.

1st position = 10, 2nd position = 9, 3rd position = 8, 4th position = 7, 5th position = 6, 6th position = 5, 7th position = 4, 8th position = 3. Total number of passwords combination possible in 8 digit is equivalent to $\frac{10!}{2}$ .

Total number of passwords combination possible for each position in 9 digit.

1st position = 10, 2nd position = 9, 3rd position = 8, 4th position = 7, 5th position = 6, 6th position = 5, 7th position = 4, 8th position = 3, 9th position = 2. Total number of passwords combination possible in 9 digit is equivalent to $\frac{10!}{1}$ .

Total number of passwords combination possible for each position in 10 digit.

1st position = 10, 2nd position = 9, 3rd position = 8, 4th position = 7, 5th position = 6, 6th position = 5, 7th position = 4, 8th position = 3, 9th position = 2, 10th position = 1. Total number of passwords combination possible in 10 digit is equivalent to 10!.

Adding them up and multiplying by $\frac{1}{5} \ mins$ to get the total number of time needed to guarantee access to database = $[\frac{10!}{2}\times\ \frac{10!}{1} \times 10!] \frac{1}{5}\ mins = \frac{10!}{2}$

The function below takes one parameter: a list of numbers (num_list). Complete the function to return a new list containing only

agasfer [191]

Answer:

Following are the program in the Python Programming language.

#define function

def negative_num(num_list):

#set list type variable

nlist=[]

#set the for loop

for n in num_list:

#check negative numbers

if(n<0):

#add the value of n in list

nlist.append(n)

#return list

return nlist

#set new list type variable that store list

newl=[-5,8,-6,3,-4,9,-7]

#print and call the function

print(negative_num(newl))

<u>Output</u>:

[-5, -6, -4, -7]

Explanation:

Here, we define the function "negative_num" and pass an argument "num_list" in its parameter and inside the function.

Set new list data type variable "nlist".
Set the for loop which iterate as the list.
Set the if conditional statement to check the value of the list is less than 0 then, add that negative values in the variable "nlist".
Then, return the new list.

Finally, we set a variable "newl" which store the list of negative and positive numbers then, we print and call the function.
