The Cartesian product of two lists of numbers A and B is defined to be the set of all points (a,b) where a belongs in A and b belongs in B. It is usually denoted as A x B, and is called the Cartesian product since it originated in Descartes' formulation of analytic geometry.
a. True
b. False
The properties and origin of the Cartesian product as stated in the paragraph
is true, and the correct option is option;
a. True
The reason why the above option is correct is stated as follows;
In set theory, the Cartesian product of two number sets such as set A and set
B which can be denoted as lists of numbers is represented as A×B and is the
set of all ordered pair or points (a, b), with a being located in A and b located
in the set B, which can be expressed as follows;
[tex]\left[\begin{array}{c}A&x&y\\z\end{array}\right] \left[\begin{array}{ccc}B(1&2&3)\\\mathbf{(x, 1)&\mathbf{(x, 2)}&\mathbf{(x, 3)}\\\mathbf{(y, 1)}&\mathbf{(y, 2)}&\mathbf{(y, 3)}\\\mathbf{(z, 1)}&\mathbf{(z, 2)}&\mathbf{(z, 3)}\end{array}\right]}[/tex]
The name Cartesian product is derived from the name of the philosopher,
scientist and mathematician Rene Descartes due to the concept being
originated from his analytical geometry formulations

In the Gradient Descent algorithm, we are more likely to reach the global minimum, if the learning rate is selected to be a large value.
a. True
b. False
Answer:
false i think.
Explanation:
Gradient Descent is more likely to reach a local minima. because starting at different points and just in general having a different starting point, will lead us to a different local minimum( aka the lowest point closest to the starting point). if alpha(the learning rate) is too large, gradient descent may fail to converge and may even diverge.

Alice and Bob are unknown to each other. Alice wants to send an encrypted message to Bob. So it chooses a KDC which is known to both Alice and Bob (protocol in page 338). Alice and KDC have A5 (hexa) as a shared key. Bob and KDC have 4B (hexa) as a shared key. Alice sends a request to KDC to generate a session key so it can communicate with Bob. KDC generates 56(hexa) as a session key. Alice intends to send 13 (hexa) as a message to Bob. For simplicity assume that the encryption and decryption operations are simply XOR operation of the key with the message. Answer the following.
1. What information does KDC send to Alice? Show as hex characters.
2. What information does Alice send to Bob? Show as hexa characters.
3. What message does Bob retrieve after decryption? Show as hexa characters.
3. ¿Qué mensaje recupera Bob después del descifrado? Mostrar como caracteres hexadecimales.

12. In cell A14, use the INDEX function and structured references to display the value in the first row and first column of the AcademicGroups table.
Answer:index(E3:H12,1)
Explanation:
Answer: =INDEX(AcademicGroups,1,1)
Explanation:
Use the INDEX function (fx) button and you will be provided two different arguments to choose from.
Select the argument: array,row,num,column,num
In the Array section, click the up-arrow and then highlight the range A2:G12 (this is the AcademicsGroups table).
In the Row_num section, enter the number 1
In the Column_num section, enter the number 1
Press OK
Hopefully the logic behind this, after seeing it, makes sense.
Suppose we have 999 records of employees Emp1, Emp2, Emp5, Emp6 and so on up to Emp998 and Emp999 stored in a sequence. Hence, records are nothing but a row in the table. In the employee table, we want to insert new records Emp3 and Emp4 in the sequence, and once we have done insertion we need to update and retrieve the record efficiently to optimize the performance of a database by minimizing the access time when query is being executed.
You are required to solve the problem with the index sequential access method with pros and cons in the given scenario
The records in the table represents the employee ID of each employee. Assume the table name is EMPLOYEES and the field name of employee IDs is ID, the following SQL query inserts Emp3 and Emp4 into the employees table.
INSERT INTO EMPLOYEES (ID) values (Emp3), (Emp4)
The advantage of using ISAM is that priorities are given to the indices of the records being inserted. So, Emp3 and Emp4 will be inserted immediately after Emp2.
However, a major disadvantage of using ISAM is that it is very expensive to keep the indices in a sequential order;

You have n warehouses and n shops. At each warehouse, a truck is loaded with enough goods to supply one shop. There are m roads, each going from a warehouse to a shop, and driving along the ith road takes d i hours, where d i is an integer. Design a polynomial time algorithm to send the trucks to the shops, minimising the time until all shops are supplied.
Following are the steps of the polynomial-time algorithm:
Split the routes according to their categorizationAssuming that mid = di of the middle road, low = road with the least di, and high = road with the highest di, we may do a binary search on the sorted list.All shops must be approachable only using these roads for every road, from low to mid.Check if all shops can be reached from[tex]\bold{ low \ to\ mid+1}[/tex] using only these roads.There is a solution if every shop can be reached by road only up to [tex]\bold{mid+1}[/tex], but not up to mid.You can [tex]\bold{set \ low = mid+1}[/tex] if all businesses aren't accessible using both [tex]\bold{mid\ and\ mid+1}[/tex] roads.If every shop could be reached using both mid and mid+1, then set high to mid-1.With these layouts of businesses and roads, no response can be given because [tex]\bold{ low > high}[/tex]You can do this by [tex]\bold{set\ mid = \frac{(low + high)}{2}}[/tex]The new low, mid, and high numbers are used in step (a).In a minimum amount of time, this algorithm will determine the best strategy to supply all shops.

3. Write the function that would find the total values in column J (2 marks)
4. Write the function that would count all values.
(2 marks)
5. Write the function that would count the number of
occurrences of 9 in the entire range
(3 marks)
Answer:
I love Microsoft Excel!
Explanation:
2 - The function that would find the average of a particular range is =AVERAGE(). This is used to find the average of something by calculating the arithmetic mean (or just "mean").
3 - The function that would find the total values within a particular range---or in this case, Column J---you would use the =SUM() function. This will add up all of the values in the range you selected. An example could be that Column X has the values of 5, 6, 12, 45, 3. =SUM(X1:X5) = 71.
4 - The function that would count all values is defined as =COUNT(). An example would be =COUNT(A1:A10).
5 - The function that would count the number of occurrences within a particular range is defined as =COUNTIF(). Within the parentheses, you would put the range of data that you are working with. Then, in quotations, you would put the name or value that you are trying to find.
In your case, it would be =COUNTIF(range,"9") ((I put range in there since I do not know what your range is as it is not defined within the context of this question))
