Answer:
Following are the code to the given question:
#include<iostream>//header file
#include<iomanip>//header file
using namespace std;
int main()//main method
{
double temperatures[7][2];//defining a double array temperatures
double lowAvg=0, highAvg=0;//defining a double variable
for(int i = 0;i<7;i++)//defining loop to input the value
{
cout<<"Enter day "<<(i+1)<<" highest temperatures: ";//print message
cin>>temperatures[i][0];//input highest temperatures value
cout<<"Enter day "<<(i+1)<<" lowest temperatures: ";//print message
cin>>temperatures[i][1];//input lowest temperatures value
}
cout << fixed << setprecision(1);//using the setprecision method
for(int i = 0;i<7;i++)//defining loop to calculating the Average of the
{
highAvg += temperatures[i][0];//holding highest value
lowAvg += temperatures[i][1];//holding lowAvg value
}
cout<<"Average high temperature = "<<highAvg/7<<endl;//calculate amd print highest temperature Average
cout<<"Average low temperature = "<<lowAvg/7<<endl;//calculate amd print lowest temperature Average
return 0;
}
Output:
Please find the attached file.
Explanation:
In this code, a 2D array "temperatures" and two-variable "highAvg, lowAvg" as double is declared, that uses the two for loops.In the first loop, it uses an array to input the value from the user-end.In the second loop, it uses the double variable that calculates the average value of the temperature.

Answers
Answer:
.isLeapYear (1900) will return an incorrect response
Explanation:
Given
The above method
Required
Which method call will give an incorrect response
(a) will return an incorrect response because 1900 is not a leap year.
When a year is divisible by 4, there are further checks to do before such year can be confirmed to be a leap year or not.
Since the method only checks for divisibility of 4, then it will return an incorrect response for years (e.g. 1900) that will pass the first check but will eventually fail further checks.
Hence, (a) answers the question;

Write a C++ program to accept a 5 digit integer and to validate the input based on the following rules.
Rules
1) The input number is divisible by 2. 2) The sum of the first two digits is less than last two digits. if the input number satisfies all the rules, the system prints valid and invalid, otherwise,
Example 1:
Enter a value: 11222
Output: Input number is valid
Example 2:
Enter a value: 1234
Output: Input number is invalid
Answers
Answer:
#include <iostream>
#include <string>
#include <regex>
using namespace std;
int main()
{
cout << "Enter a 5-digit number: ";
string number;
cin >> number;
bool valid = regex_search(number, regex("^\\d{4}[02468]$"));
if (valid) {
valid = stoi(number.substr(0, 1)) + stoi(number.substr(1, 1))
< stoi(number.substr(3, 1)) + stoi(number.substr(4, 1));
}
cout << number << (valid ? " is valid" : " is invalid");
}
Explanation:
Regular expressions can do all of your checking except for the sum of digits check. The checks are i.m.o. easiest if you don't treat the input as a number, but as a string with digits in it.
The regex means:
^ start of string
\d{4} exactly 4 digits
[02468] one of 0, 2, 4, 6 or 8 (this is what makes it even)
$ end of string
spherevolume = (4.0 / 3.0) * pival * sphereradius * sphereradius * sphereradius ;
Answers
Answer:
The program in Python is as follows:
pival = 3.142
sphereradius = float(input("Radius: "))
spherevolume = [tex](4.0 / 3.0)[/tex] * [tex]pival[/tex] * sphereradius * [tex]sphereradius[/tex] * sphereradius
print(spherevolume)
Explanation:
The missing part of the program is to calculate the volume of a sphere.
The program in Python (in the answer section) is implemented using the already used variables.
Initialize pi
pival = 3.142
Get input for radius
sphereradius = float(input("Radius: "))
Calculate the volume
spherevolume = [tex](4.0 / 3.0)[/tex] * [tex]pival[/tex] * sphereradius * [tex]sphereradius[/tex] * sphereradius
Print the calculated volume
print(spherevolume)

Create a method called nicknames that passes an array as a parameter. Inside the method initialize it to hold 5 names of your choice. Use the for each enhanced loop to print the elements of the array.
Answers
//======METHOD DECLARATION=========//
//method name: nicknames
//method return type: void
//method parameter: an array reference
public static void nicknames(String [] names){
//initialize the array with 5 random names
names = new String[] {"John", "Doe", "Brian", "Loveth", "Chris"};
//using an enhanced for loop, print out the elements in the array
for(String n: names){
System.out.print(n + " ");
}
}
Explanation:
The program is written in Java. It contains comments explaining important parts of the code. Kindly go through these comments.
A few things to note.
i. Since the method does not return any value, its return type is void
ii. The method is made public so that it can be accessible anywhere in and out of the class the uses it.
iii. The method is made static since it will most probably be called in the static main method (at least for testing in this case)
iv. The method receives an array of type String as parameter since the names to be stored are of type String.
v. The format of initializing an array manually should follow as shown on line 7. The new keyword followed by the array type (String), followed by the square brackets ([]) are all important.
vi. An enhanced for loop (lines 9 - 11) is a shorthand way of writing a for loop. The format is as follows;
=> The keyword for
=> followed by an opening parenthesis
=> followed by the type of each of the elements in the array. Type String in this case.
=> followed by a variable name. This holds an element per cycle of the loop.
=> followed by a column
=> followed by the array
=> followed by the closing parenthesis.
=> followed by a pair of curly parentheses serving as a block containing the code to be executed in every cycle of the loop. In this case, the array elements, each held in turn by variable n, will be printed followed by a space.
A complete code and sample output for testing purposes are shown as follows:
==================================================
public class Tester{
//The main method
public static void main(String []args){
String [] names = new String[5];
nicknames(names);
}
//The nicknames method
public static void nicknames(String [] names){
names = new String[] {"John", "Doe", "Brian", "Loveth", "Chris"};
for(String n: names){
System.out.print(n + " ");

Output:John Doe Brian Loveth Chris

A student is conducting an experiment in which he adds an inhibitor to an enzyme-catalyzed reaction that contains alkaline phosphatase. When the student first adds the inhibitor, the reaction rate decreases, however, he can return the reaction rate to normal by adding a large quantity of substrate. What type of inhibitor is the student using, non-competitive or competitive?
Answers
Answer:
competitive
Explanation:
An inhibitor is a substance that hinders the action of an enzyme. An inhibitor may be competitive or non competitive.
A competitive inhibitor is an inhibitor that is very similar to the substrate hence it binds to the enzyme instead of the substrate. A noncompetitive inhibitor binds to a site that is different from the active site. This site is called an allosteric site.
If we look at the experiment described in the question, the reaction rate decreases upon addition of the inhibitor. This effect is reversed by adding a large quantity of substrate.
The implication of this observation is that the enzyme and the inhibitor compete for the active site on the substrate.
Hence the inhibitor is a competitive inhibitor.
Answer:
competitive inhibitor is the students using

Answer: Last summer, my family and I took a trip to Jamaica. My favorite part of the trip was when we went to a place called the Luminous Lagoon. We ate dinner and waited for the sun to go down. Then we boarded a boat and went out into the lagoon. That’s when the magic started.
At first we could not see very much in the darkness except for the stars in the sky. After a few minutes, however, I noticed some fish swimming in the water. They didn’t look like ordinary fish. These fish were glowing! Our guide explained that the glow came from tiny creatures in the water called dinoflagellates. These little animals are not visible to us, but their bodies produce light using something called bioluminescence, just like fireflies. There are so many of these creatures in Luminous Lagoon that the water around them seems to glow.
After our guide explained these facts to us, he told us to put our hands in the water. I was not sure if it would work, but I tried it. When I did, my hand looked like it belonged to a superhero! It was glowing bright blue. I hope someday I get to return to the Luminous Lagoon. The lights in the water were much more entertaining than the ones in the sky.

Answers
The question is incomplete. The complete question is :
Holly the Hacker has a list of 100,000 common passwords. She wants to use this list to break into UNIX-like systems that use a password file with lines consisting of:
The user's ID in plaintext.
10 bits of randomly chosen "salt," in plaintext.
The user's password, concatenated with the salt, and then encrypted.
There are very many such systems around the world, and Holly plans to steal the password files from as many as she can. The average system has 50 users in its password file.
Holly wants to create a master list of the encrypted versions of all the 100,000 passwords on her list, encrypted with all possible salt values. To create this master list, approximately how many encryptions of a password-concatenated-with-salt would Holly have to perform?
A. 2 million
B. 5 million
C. 100 million
D. 1 million
Solution :
It is given that the hacker, Holly wants break into the UNIX-like systems using 100,000 common passwords that she has on her list. The system has at an average of 50 users in the password files.
Therefore, to create a master list, Holly have to perform about 50 x 100,000 = 5,000,000 encryptions for the password concatenated-with-salt.
Thus the correct option is option (B). 5 million
You trained a binary classifier model which gives very high accuracy on thetraining data, but much lower accuracy on validation data. The following maybe true:
a. This is an instance of overfitting.
b. This is an instance of underfitting.
c. The training was not well regularized.
d. The training and testing examples are sampled from different distributions.
Answers
Answer:
a. This is an instance of overfitting.
Explanation:
In data modeling and machine learning practice, data modeling begins with model training whereby the training data is used to train and fit a prediction model. When a trained model performs well on training data and has low accuracy on the test data, then we say say the model is overfitting. This means that the model is memorizing rather Than learning and hence, model fits the data too well, hence, making the model unable to perform well on the test or validation set. A model which underfits will fail to perform well on both the training and validation set.
