Using the Internet, search and discuss why naming conventions are important and why programmers should consistently follow them. What problems can arise in naming variables if one convention is not followed.
Answer:
Answered below
Explanation:
Some variable naming conventions include;
1) Variable should begin with either a letter or an underscore.
2) Variables having multiple words should have the first letter of every word after the first word, capitalized. This is the camelCase style.
3) variables should not be named after any of the inbuilt keywords except on special operations to override the original function of such keyword.
4) variable names are case-sensitive.
The importance of following these conventions is to maintain readability and consistency of code. Failure to follow these conventions may lead to chaotic codes, bugs and inefficient performance.
Complete the getOdds method so it returns a new ArrayList of Integers containing all odd Integers from the parameter ArrayList vals in the order they originally appeared. The contents of vals should not change. For example if an ArrayList containing the Integers 2, 5, 8, 6, 7, 3, 12 in that order is passed as a parameter to getOdds, it should return an ArrayList containing the Integers 5, 7, 3 in that order. Write your getOdds method in the U7_L2_Activity_Three class. Use the runner class to test your method but do not add a main method to your U7_L2_Activity_Three.java file or your code will not be scored correctly.

Recently, Walmart offered a wireless data contract based on bandwidth used, with a minimum monthly charge of $42 for up to 5 gigabytes (GB) of use. Additional GB can be purchased at the following rates: $12 for an additional 1 GB, $28 for an additional 3 GB, and $44 for a capacity of 10 GB. What is the cost for a user who is expecting to use 9 GB
Answer:
For 9GB of data the user would pay $82 monthly!
Explanation:
To start off, our end goal is 9GB. We have the equation 9 = ? We can add up to our solutions with 1GB, 3GB, and 10GB. We can immediately rule out 10GB, since 9GB ≠ 10GB. To cost the least amount of money we can add up 3GB and 1GB = 4GB + 5GB = 9GB!
So, our equation is 3GB + 1GB + 5GB = 9GB, now lets figure out the cost!
$28 + $12 + $42 = $82
For 9GB of data the user would pay $82 monthly!
Hope this Helps! :)

What will be the output of the following:
i) 10%2 ii)10**2
Answer:
The output of 10%2 is 0The output of 10**2 is 100Explanation:
We will see the output one by one.
i) 10%2
The statement consists of modulus operator also called as remainder operator. The remainder operator gives the remainder when the first operand is divided by the second operand. The remainder operator only works on integers.
So the output of the statement will be: 0
ii)10**2
The double asterisk is used for exponent. The second operand is the power and the first operand is the base.
So the output will be: 10**2 = 10^2 = 100

If an insurance policy covers individual losses up to $10,000 and has a deductible of
$500, the insured will be paid how much in the event of a covered loss of $5,000?
Answer: $4500
Explanation:
The deductible is the amount that the insured that is, the policy holder will have to pay. In this case, there is a covered loss of $5000 and the insured has a deductible of $500.
Therefore, the amount that the insured will be paid will be the difference between $5000 and the deductible of $500. This will be:
= $5000 - $500
= $4500
we need to send 254 kbps over a noiseless channel with a bandwidth of 15 khz. how many signal levels do we need
Answer:
The level of the signal is 353.85
Explanation:
Data rate determines the speed of the data transmission.
The data rate depends on the following factors
The available bandwidthnumbers of signal levelsthe quality of the channel ( Means the level of noise )The data is transmitted either from a noiseless channel or a noisy channel.
The given quality of the channel in the question is noiseless.
Use the following formula to calculate the signal levels
Bit rate = 2 x bandwidth x [tex]Log_{2}[/tex] ( signal level )
where
Transmitted Data = 254 kbps = 254,000 bps
Bandwidth = 15 khz = 15,000 hz
Placing values in the formula
254,000 = 2 x 15,000 x [tex]Log_{2}[/tex] ( L )
254,000 = 30,000 x [tex]Log_{2}[/tex] ( L )
254,000 / 30,000 = [tex]Log_{2}[/tex] ( L )
8.467 = [tex]Log_{2}[/tex] ( L )
L = [tex]2^{8.467}[/tex]
L = 353.85 levels

What is a Variable Expense?Business expenses can be classified as either fixed (invariable) or variable. A fixed expense does not change based on a business’s other activities. Costs like rent and administrative salaries are fixed costs, which remain the same no matter how much a business is producing. Imagine a factory that produces pencils — the cost of renting the factory building will remain the same, month after month, no matter how many pencils the company actually produces.
Variable expense ratio expresses variable expenses as a proportion of a company's sales. To calculate the variable expense ratio, simply divide the company's total variable expenses by the company's total net sales. To express the result as a percentage, simply multiply it by 100.
Therefore, A Task can be created in Outlook 2016 by clicking on the Tasks navigation item, or by clicking on the View tab. Thus, option A is correct.

Which example can be used to perform a binary search?
Answer:
In any case, binary search can be used to solve more extensive scope of problem, for example, finding the next smallest or next-biggest element in an array comparative with the target regardless of whether it is present or missing in the array.
Explanation:
In computer science, binary search, otherwise called logarithmic search, is a search calculation that finds the position of an objective incentive inside an arranged array. Binary search compares the target value to the center component of the array. In the event that they are not equivalent, the half in which the value can't lie is dispensed with and the search proceeds on the other half, again taking the center value to contrast with the target value, and continues this until the target value is found. On the off chance that the search ends with the other half being empty, the target value isn't in the array.
Binary search is quicker than linear search aside from small arrays. Nonetheless, the array should be arranged first to have the option to apply binary search. There are particular data structures intended for quick looking, for example, hash tables, that can be looked through more effectively than binary search.
Write a program that takes a set of numbers and determines which is the smallest. Ask the user for the following information, in this order: A terminating value (real number). The user will enter this value again later, to indicate that he or she is finished providing input. A sequence of real numbers. Keep asking for numbers until the terminating value is entered.
Answer:
This solution is implemented in C++:
#include<iostream>
#include<bits/stdc++.h>
using namespace std;
int main(){
double termnum;
cout<<"Terminating number: ";
cin>>termnum;
double num;
vector<double>numbers;
cout<<"Number: ";
cin>>num;
while(num!=termnum){
numbers.push_back(num);
cout<<"Number: ";
cin>>num;
}
double smallest = numbers.at(0);
for(double x:numbers){
if(x < smallest){
smallest = x;
}
}
cout<<"The smallest is "<<smallest;
return 0;
}
Explanation:
This declares the terminating variable as double
double termnum;
The next italicized lines prompts user for terminating value
cout<<"Terminating number: ";
cin>>termnum;
This declares the user input variable as double
double num;
This declares vector of numbers as double
vector<double>numbers;
The next italicized lines prompts user for number
cout<<"Number: ";
cin>>num;
The following iteration is repeated until the terminating value equals the number supplies by the user
while(num!=termnum){
This pushes the number to a vector
numbers.push_back(num);
The italicized lines prompts user for another number
cout<<"Number: ";
cin>>num;
}
This declares and initializes variable smallest
double smallest = numbers.at(0);
The following for loop determines the smallest of the number set
for(double x:numbers){
if(x < smallest){
smallest = x;
}
}
This prints the smallest of the set
cout<<"The smallest is "<<smallest;
return 0;

. Else-if is good selection statement that help us to solve problems in C++,mostly times same problem of same nature can also be solved via switch statement. Which one you prefer to use and why?
Answer:
Else-If statements
Explanation:
Personally, I prefer using Else-If statements for conditional statements since you can start with and If statement and add to it if necessary. Aside from this, Else-If statements also allow you to add more than one condition to be met by using tags such as and or and not. Switch statements are better in scenarios where you have a set of possible inputs or results and need a specific event to happen for each input/result, but this is not as common of a scenario so Else-If is usually my go-to conditional statement.
