Answer:

Yes, the purpose of a database in a way is to stop people from using spreadsheets but, it is also so much more.

Explanation:

Databases are a vastly improved form of a spreadsheet. They allow Computer Scientists to automatize a company's information. Giving them the ability to instantly add, retrieve, and modify specific information within a database of hundreds or even thousands of entries. All this with little or no human input. Thus saving a company time and money as opposed to using a regular spreadsheet which requires manual input from an employee.

miskamm [114]

Answer:

lst = [11, 603, 99, 7, 582, 1];

print("The index of the middle element: " + str(int(len(lst)/2)))

print("The middle element: " + str(lst[int(len(lst)/2)]))

lst.sort()

sorted_lst = lst.reverse()

print("The list in descending order: " + str(lst))

first_number = lst.pop(0)

lst.append(first_number)

print("New lst: "+ str(lst))

Explanation:

- Initialize a list

- Find the middle index, int(len(lst)/2)

- Find the middle element, lst[int(len(lst)/2)]

- Sort the list in descending order (First sort the list in ascending order than reverse it)

- Get the first element using pop method, and append it to the end using append method

- - - - -

a) 0 == 1 == 2 --> Always evaluates false

b) 2 + (3 == 4) + 5 == 7 --> Evaluates true

c) 1 < -1 == 3 > 4 --> Always evaluates false

From a neural network with 11 input variables, one hidden layer with three hidden units, and one output variable, how many param

e-lub [12.9K]

Answer:

Explanation:

Given that:

A neural network with 11 input variables possess;

one hidden layer with three hidden units; &

one output variable

For every input, a variable must go to every node.

Thus, we can calculate the weights of weight with respect to connections to input and hidden layer by using the formula:

= ( inputs + bias) × numbers of nodes

= (11 + 1 ) × 3

= 12 × 3

= 36 weights

Also, For one hidden layer (with 3 nodes) and one output

The entry result for every hidden node will go directly to the output

These results will have weights associated with them before computed in the output node.

Thus; using the formula

= (numbers of nodes + bais) output, we get;

= ( 3+ 1 ) × 1

= 4 weights

weights with respect to input and hidden layer total = 36

weights with respect to hidden and output layer total = 4

Finally, the sum of both weights is = 36 + 4

= 40
