g Add a throw statement to the processNumbers function that throws the message "An element in the list is not a number." if one of the elements in toProcess is not a number. Hint: The function isNaN() returns true if the parameter is not a number.
Answers
Answer and Explanation:
function processNumbers(alist){
var Ourarray= new array(alist);
Ourarray.foreach(
if(isNaN()){
Console.log( "An element in the list is not a number."};
break;
}
}
processNumbers(alist)
From the above, we have defined a function that takes an array parameter(the following array variable will make sure of that). We test each element in the array using foreach array function. The for each function runs the if statement and if isNan is true for each of the elements in the array.

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
Answers
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
Therefore, the statement is true

A computer has many resources. A resource can be memory, disk drive, network bandwidth, battery power, or a monitor. It can also be system objects such as shared memory or a linked list data structure. This principle is based in object-oriented programming (OOP). In OOP, a class definition encapsulates all data and functions to operate on the data. The only way to access a resource is through the provided interface. Which security principle are we referring to
Answers
Answer:
The security principle being referred to here is:
Resource Encapsulation.
Explanation:
Resource Encapsulation is one of the cybersecurity first principles. It allows access or manipulation of the class data as intended by the designer. The cybersecurity first principles are the basic or foundational propositions that define the qualities of a system that can contribute to cybersecurity. Other cybersecurity first principles, which are applied during system design, include domain separation, process isolation, modularization, abstraction, least principle, layering, data hiding, simplicity, and minimization.
Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (current_price * 0.051) / 12. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f}'.format(your_value))
Answers
Answer:
The program in Python is as follows:
current_price = int(input("Current Price: "))
last_price = int(input("Last Month Price: "))
change = current_price - last_price
mortgage = (current_price * 0.051) / 12
print('Change: {:.2f} '.format(change))
print('Mortgage: {:.2f}'.format(mortgage))
Explanation:
This gets input for current price
current_price = int(input("Current Price: "))
This gets input for last month price
last_price = int(input("Last Month Price: "))
This calculates the price change
change = current_price - last_price
This calculates the mortgage
mortgage = (current_price * 0.051) / 12
This prints the calculated change
print('Change: {:.2f} '.format(change))
This prints the calculated monthly mortgage
print('Mortgage: {:.2f}'.format(mortgage))
Answer:
current_price = int(input())
last_months_price = int(input())
change = current_price - last_months_price
mortgage = current_price * 0.051 / 12
print('This house is $', end= '')
print(current_price, end= '. ')
print('The change is $', end= '')
print(change, end= ' ')
print('since last month.')
print('The estimated monthly mortgage is $', end= '')
print(mortgage, end='0.\n')

The following code is written in Python. The tax calculator program was not provided, therefore I created a tax calculator that takes in the total price as an input and adds a 7% tax to it. Then it uses the round() function to make sure that the total is outputted as a decimal with two decimal digits at most.
def taxCalculator(price):
total = price * 1.07
formattedTotal = round(total, 2)

the base on which the number n=(34)? is written if it has a value of n= (22)10
Answers
If I'm understanding the question correctly, you are looking for an integer b (b ≠ 0, b ≠ 1) such that
[tex]34_b = 22_{10}[/tex]
In other words, you're solving for b such that
3×b ¹ + 4×b ⁰ = 22
or
3b + 4 = 22
Solving this is trivial:
3b + 4 = 22
3b = 18
b = 6
So we have
34₆ = 22₁₀
