Write an expression that will cause the following code to print "Equal" if the value of sensorReading is "close enough" to targetValue. Otherwise, print "Not equal". Hint: Use epsilon value 0.0001. Ex: If targetValue is 0.3333 and sensorReading is (1.0/3.0), output is: Equal
Answer:
The expression that does the comparison is:
if abs(targetValue - sensorReading) < 0.0001:
See explanation section for full source file (written in Python) and further explanation
Explanation:
This line imports math module
import math
This line prompts user for sensor reading
sensorReading = float(input("Sensor Reading: ")
This line prompts user for target value
targetValue = float(input("Target Value: ")
This line compares both inputs
if abs(targetValue - sensorReading) < 0.0001:
print("Equal") This is executed if both inputs are close enough
else:
print("Not Equal") This is executed if otherwise
The expression that will cause the following code to print "Equal" if the value of sensorReading is "close enough" to targetValue and print "Not equal" if otherwise is as follows;
sensorReading = float(input("write your sensor reading: "))
targetValue = float(input("write your target value: "))
if abs(sensorReading - targetValue) < 0.0001:
print("Equal")
else:
print("not Equal")
The code is written in python.
Code explanationThe variable sensorReading is used to store the user's inputted sensor reading.The variable targetValue is used to store the user's inputted target value.If the difference of the sensorReading and the targetValue is less than 0.0001. Then we print "Equal"Otherwise it prints "not Equal"learn more on python code here; https://brainly.com/question/14634674?referrer=searchResults
For an alternative to the String class, and so that you can change a String's contents, you can use_________ .
a. char.
b. StringHolder.
c. StringBuilder.
d. StringMerger.
Answer:
c. StringBuilder
Explanation:
An alternative to the String class would be the StringBuilder Class. This class uses Strings as objects and allows you to mix and match different strings as well as adding, removing, implementing, and modifying strings themselves as though they were similar to an array. Unlike the string class StringBuilder allows you to modify and work with a combination of strings in the same piece of data as opposed to having various objects and copying pieces which would take up more memory.

Write a program that finds the number of items above the average of all items. The problem is to read 100 numbers, get the average of these numbers, and find the number of the items greater than the average. To be flexible for handling any number of input, we will let the user enter the number of input, rather than fixing it to 100.
Answer:
Written in Python
num = int(input("Items: "))
myitems = []
total = 0
for i in range(0, num):
item = int(input("Number: "))
myitems.append(item)
total = total + item
average = total/num
print("Average: "+str(average))
count = 0
for i in range(0,num):
if myitems[i] > average:
count = count+1
print("There are "+str(count)+" items greater than average")
Explanation:
This prompts user for number of items
num = int(input("Items: "))
This creates an empty list
myitems = []
This initializes total to 0
total = 0
The following iteration gets user input for each item and also calculates the total
for i in range(0, num):
item = int(input("Number: "))
myitems.append(item)
total = total + item
This calculates the average
average = total/num
This prints the average
print("Average: "+str(average))
This initializes count to 0
count = 0
The following iteration counts items greater than average
for i in range(0,num):
if myitems[i] > average:
count = count+1
This prints the count of items greater than average
print("There are "+str(count)+" items greater than average")

Explain why it is not necessary for a program to be completely free of defects before it is delivered to its customers?
Answer:
Testing is done to show that a program is capable of performing all of its functions and also it is done to detect defects.
It is not always possible to deliver a 100 percent defect free program
A program should not be completely free of all defects before they are delivered if:
1. The remaining defects are not really something that can be taken as serious that may cause the system to be corrupt
2. The remaining defects are recoverable and there is an available recovery function that would bring about minimum disruption when in use.
3. The benefits to the customer are more than the issues that may come up as a result of the remaining defects in the system.

Write a function called matches that takes two int arrays and their respective sizes, and returns the number of consecutive values that match between the two arrays starting at index 0. Suppose the two arrays are {3, 2, 5, 6, 1, 3} and {3, 2, 5, 2, 6, 1, 3} then the function should return 3 since the consecutive matches are for values 3, 2, and 5.
Answer:
Written in C++
int matches(int arr1[], int arr2[], int k) {
int count = 0;
int length = k;
for(int i =0; i<length; i++) {
if(arr1[i] == arr2[i]) {
count++;
}
}
return count;
}
Explanation:
This line defines the function
int matches(int arr1[], int arr2[], int k) {
This line initializes count to 0
int count = 0;
This line initializes length to k
int length = k;
This line iterates through the array
for(int i =0; i<length; i++) {
The following if statement checks for matches
if(arr1[i] == arr2[i]) {
count++;
}
}
This returns the number of matches
return count;

Answer:
The mailman would sometimes take a different path to deliver each letter to your home.
Explanation:
Options:
The mailman would sometimes take a different path to deliver each letter to your home.
Letters would be written on the outside of envelopes for all to read instead of letters put inside envelopes.
Routers work in different ways and they take the fastest route no matter what is the direction they have to take, so they travel to several servers trying to find the fastest path to their destination, it changes almost everytime because of the use of servers and the conection speed of the different routes they can connect to, so that would be the option.

Which query is used to list a unique value for V_CODE, where the list will produce only a list of those values that are different from one another?
a. SELECT ONLY V_CODE FROM PRODUCT;
b. SELECT UNIQUE V_CODE FROM PRODUCT;
c. SELECT DIFFERENT V_CODE FROM PRODUCT;
d. SELECT DISTINCT V_CODE FROM PRODUCT;
Answer:
d. SELECT DISTINCT V_CODE FROM PRODUCT;
Explanation:
The query basically lists a unique value for V_CODE from PRODUCT table.
Option a is incorrect because it uses ONLY keyword which does not use to list a unique value for V_CODE. Instead ONLY keyword is used to restrict the tables used in a query if the tables participate in table inheritance.
Option b is incorrect because it is a constraint that ensures that all values in a column are unique.
Option c is incorrect because DIFFERENT is not a keyword
Option d is correct because the query uses SELECT statement and DISTINCT is used to select only distinct or different values for V_CODE.
The query that should be used for a unique value is option d.
The following information should be considered:
The query listed the unique value for V_CODE arise from the PRODUCT table.Option A is wrong as it used ONLY keyword that does not represent the unique value. Option B is wrong as it is constraint where the columns values are considered to be unique.Option C is wrong as DIFFERENT does not represent the keyword. Option D is right as query applied SELECT and DISTINCT that represent different values.Therefore we can conclude that the correct option is D.

Define a function called sum, for a given an array and an int representing its size, if the size is at least 3, then sum up all elements whose indices are a multiple of 3 and return that value, otherwise, return 0.
Answer:
Written in C++
int sum(int arr[], int size) {
int total = 0;
if(size>=3) {
for (int i = 0; i < size; ++i) {
if(i%3 == 0) {
total += arr[i];
}
}
}
return total;
}
Explanation:
This line defines the function
int sum(int arr[], int size) {
This line initializes sum to 0
int total = 0;
This line checks if size is at least 3
if(size>=3) {
This loop iterates through the array
for (int i = 0; i < size; ++i) {
The following adds multiples of 3
if(i%3 == 0) {
total += arr[i];
}
}
}
This returns the calculated sum
return total;

Write a function addUpSquaresAndCubes that adds up the squares and adds up the cubes of integers from 1 to N, where N is entered by the user. This function should return two values - the sum of the squares and the sum of the cubes. Use just one loop that generates the integers and accumulates the sum of squares and the sum of cubes. Then, write two separate functions sumOfSquares and sumOfCubes to calculate and return the sums of the squares and sum of the cubes using the explicit formula below.
Answer:
All functions were written in python
addUpSquaresAndCubes Function
def addUpSquaresAndCubes(N):
squares = 0
cubes = 0
for i in range(1, N+1):
squares = squares + i**2
cubes = cubes + i**3
return(squares, cubes)
sumOfSquares Function
def sumOfSquares(N):
squares = 0
for i in range(1, N+1):
squares = squares + i**2
return squares
sumOfCubes Function
def sumOfCubes(N):
cubes = 0
for i in range(1, N+1):
cubes = cubes + i**3
return cubes
Explanation:
Explaining the addUpSquaresAndCubes Function
This line defines the function
def addUpSquaresAndCubes(N):
The next two lines initializes squares and cubes to 0
squares = 0
cubes = 0
The following iteration adds up the squares and cubes from 1 to user input
for i in range(1, N+1):
squares = squares + i**2
cubes = cubes + i**3
This line returns the calculated squares and cubes
return(squares, cubes)
The functions sumOfSquares and sumOfCubes are extract of the addUpSquaresAndCubes.
Hence, the same explanation (above) applies to both functions
How does a computer interact with its environment? How is data transferred on a real computer from one hardware part to another? Describe the importance of the human interaction in the computing system.
Answer:
Explanation:
A computer system can interact with its environment using hardware that does so such as cameras, robotic arms, thermometers, smart devices etc. These hardware devices gather information from the environment and transfer it to the computer system in a format known as bits through binary electrical impulses. If the system is designed to be autonomous then the only human interaction needed would be the initial setup of the system and its hardware, once this is done the system does not need any more human interaction as long as nothing breaks.
The following equations estimate the calories burned when exercising (source): Men: Calories = ( (Age x 0.2017) — (Weight x 0.09036) + (Heart Rate x 0.6309) — 55.0969 ) x Time / 4.184 Women: Calories = ( (Age x 0.074) — (Weight x 0.05741) + (Heart Rate x 0.4472) — 20.4022 ) x Time / 4.184 Write a program with inputs age (years), weight (pounds), heart rate (beats per minute), and time (minutes), respectively. Output calories burned for men and women. Ex: If the input is 49 155 148 60, the output is:
In python:
age = float(input("How old are you? "))
weight = float(input("How much do you weigh? "))
heart_rate = float(input("What's your heart rate? "))
time = float(input("What's the time? "))
print("The calories burned for men is {}, and the calories burned for women is {}.".format(
((age * 0.2017) - (weight * 0.09036) + (heart_rate * 0.6309) - 55.0969) * (time / 4.184),
((age * 0.074) - (weight * 0.05741) + (heart_rate * 0.4472) - 20.4022) * (time / 4.184)))
This is the program.
When you enter 49 155 148 60, the output is:
The calories burned for men is 489.77724665391963, and the calories burned for women is 580.939531548757.
Round to whatever you desire.
The programming language is not stated. So, I will answer this question using Python programming language.
The program requires a sequence control structure, because it does not make use of conditions and iterations.
The program in python is as follows, where comments (in italics) are used to explain each line.
#This gets input for age, in years
age = int(input("Age (years): "))
#This gets input for weight, in pounds
weight = int(input("Weight (pounds): "))
#This gets input for heart rate, in beats per minutes
heart_rate = int(input("Heart Rate (beats per minutes): "))
#This gets input for time, in minutes
time = int(input("Time (Minutes) : "))
#This calculates the calories burnt for men
Men = ((age * 0.2017) - (weight * 0.09036) + (heart_rate * 0.6309) - 55.0969) * time / 4.184
#This calculates the calories burnt for women
Women = ((age * 0.074) - (weight * 0.05741) + (heart_rate * 0.4472) - 20.4022 ) * time / 4.184
#This prints the calories burnt for men
print("Men:", Men)
#This prints the calories burnt for women
print("Women:", Women)
At the end of the program, the program outputs the amount of calories burnt for men and women.

Answer:
Here is the Python function:
def group_by(s, fn): #method definition
group = {} #dictionary
for e in s: #for each element from s
key = fn(e) #set key to fn(e)
if key in group: #if key is in dictionary group
group[key].append(e) #append e to the group[key]
else: #if key is not in group
group[key] = [e] #set group[key] to [e]
return group #returns dictionary group
Explanation:
To check the working of the above function call the function by passing a sequence and a function and use print function to display the results produced by the function:
print(group_by([12, 23, 14, 45], lambda p: p // 10))
print(group_by(range(-3, 4), lambda x: x * x))
function group_by takes in a sequence s and a function fn as parameters. It then creates an empty dictionary group. The values of the dictionary are lists of elements from s. Each element e in a list is constructed such that fn(e) is the same for all elements in that list. Finally, the key for each value is fn(e). The function returns a dictionary.

You are given an array of integers, each with an unknown number of digits. You are also told the total number of digits of all the integers in the array is n. Provide an algorithm that will sort the array in O(n) time no matter how the digits are distributed among the elements in the array. (e.g. there might be one element with n digits, or n/2 elements with 2 digits, or the elements might be of all different lengths, etc. Be sure to justify in detail the run time of your algorithm.
Answer:
Explanation:
Since all of the items in the array would be integers sorting them would not be a problem regardless of the difference in integers. O(n) time would be impossible unless the array is already sorted, otherwise, the best runtime we can hope for would be such a method like the one below with a runtime of O(n^2)
static void sortingMethod(int arr[], int n)
{
int x, y, temp;
boolean swapped;
for (x = 0; x < n - 1; x++)

if (arr[y] > arr[y + 1])
{
temp = arr[y];
arr[y] = arr[y + 1];
arr[y + 1] = temp;
swapped = true;
