The common field cricket chirps in direct proportion to the current tem­perature. Adding 40 to the number of times a cricket chirps in a minute, then dividing by 4, gives us the temperature (in Fahrenheit degrees). Write a program that accepts as input the number of cricket chirps in fifteen seconds, then outputs the current temperature

Answers

Answer 1

Answer:

This program is written in Java programming language;

First, you should understand that:

The formula given in the question implies that the current temperature can only be calculated using measurement of time in minutes;

Given that the number of chirps is directly proportional to the temperature.

If the cricket made n chirps in 15 seconds, it will make n * (60/15) chirps in 1 minutes;

n * (60/15) = n * 4

Base on this analysis, the program is as follows

import java.util.*;

public class cricket

{

public static void main(String []args)

{

 //Declare number of chips in 1 minutes

 int num;

 Scanner input = new Scanner(System.in);

 //Prompt user for input

 System.out.print("Number of chirps (in 15 seconds): ");

 num = input.nextInt();

 //Calculate temperature  (multiply temperature by 4 to get number of chirps in minutes

 double temp = (num * 4+ 40)/4;

 //Print temperature

 System.out.print("Current Temperature = "+temp+" F");

}

}

Why is wind power a never ending source of power?

Answers

Answer:

"Wind is caused by the heating of the atmosphere which is caused by the sun. Since we have the sun we have wind, since we will never lose the sun, we will never lose the wind which means it is a never-ending source of power." It's also the reason why wind power is a form of solar energy, along with that wind power does not contribute to the heating of the Earth's surface like burning fossil fuels.

5, 6, 7, 8, 9
5, 6, 7, 8, 9, 10
6, 7, 8, 9
1, 2, 3, 4, 5, 6, 7, 8, 9

Answers

The values of x make the if condition true is 6, 7, 8, 9.

The statement "if(x > 5 and x < 10)" represents a conditional statement that checks if the value of x falls within the range of numbers greater than 5 and less than 10. To determine the values that make this condition true, we need to examine the range between 5 and 10, excluding the boundary values.

The condition explicitly states that x must be greater than 5 and less than 10. By satisfying both parts of the condition, the values of x that make the if condition true are 6, 7, 8, and 9.

These values meet the criteria of being greater than 5 and less than 10. It is important to note that the condition specifically excludes the values of 5 and 10. Therefore, they are not considered true for the given condition.

The values of x that make the if condition "x > 5 and x < 10" true are 6, 7, 8, and 9. Any values below 6 or equal to or greater than 10 do not satisfy both parts of the condition and  would not make the if statement true.

Correct option is 6, 7, 8, 9.

Instead of picking RB randomly the browser always sends all zeros. Describe an attack that is possible against this buggy browser and how to update the browser so that this attack is no longer feasible.

Answers

I have an Ipad Mini 4, and a friend of mine recently changed its' password ( they knew what the old password was ). Today, when I tried to login to it, my friend claimed they forgot the password but they could remember a few distinct details :

- It had the numbers 2,6,9,8,4, and 2 ( not all of them, but these are the only possible numbers used )
- It's a six digit password
- It definitely isn't 269842
- It definitely has a double 6 or a double 9

I have already tried 26642 and 29942 and my Ipad is currently locked. I cannot guarantee a recent backup, so I cannot reset it as I have very important files on it and lots of memories. It was purchased for me by someone very dear to me. My question is, what are the password combinations?

I have already asked this before and recieved combinations, however none of them have been correct so far.

Help is very much appreciated. Thank you for your time!

Answers

Based on the information provided, we can start generating possible six-digit password combinations by considering the following:

   The password contains one or more of the numbers 2, 6, 9, 8, and 4.

   The password has a double 6 or a double 9.

   The password does not include 269842.

One approach to generating the password combinations is to create a list of all possible combinations of the five relevant numbers and then add the double 6 and double 9 combinations to the list. Then, we can eliminate any combinations that include 269842.

Using this method, we can generate the following list of possible password combinations:

669846

969846

669842

969842

628496

928496

628492

924896

624892

924892

648296

948296

648292

948292

Note that this list includes all possible combinations of the relevant numbers with a double 6 or a double 9. However, it is still possible that the password is something completely different.

Which of the following if statements uses a Boolean condition to test: "If you are 18 or older, you can vote"? (3 points)

if(age <= 18):
if(age >= 18):
if(age == 18):
if(age != 18):

Answers

The correct if statement that uses a Boolean condition to test the statement "If you are 18 or older, you can vote" is: if(age >= 18):

In the given statement, the condition is that a person should be 18 years or older in order to vote.

The comparison operator used here is the greater than or equal to (>=) operator, which checks if the value of the variable "age" is greater than or equal to 18.

This condition will evaluate to true if the person's age is 18 or any value greater than 18, indicating that they are eligible to vote.

Let's analyze the other if statements:

1)if(age <= 18):This statement checks if the value of the variable "age" is less than or equal to 18.

However, this condition would evaluate to true for ages less than or equal to 18, which implies that a person who is 18 years old or younger would be allowed to vote, which is not in line with the given statement.

2)if(age == 18):This statement checks if the value of the variable "age" is equal to 18. However, the given statement allows individuals who are older than 18 to vote.

Therefore, this condition would evaluate to false for ages greater than 18, which is not correct.

3)if(age != 18):This statement checks if the value of the variable "age" is not equal to 18.

While this condition would evaluate to true for ages other than 18, it does not specifically cater to the requirement of being 18 or older to vote.

For each of the following relations on the set of all real numbers, decide whether or not the relation is reflexive, symmetric, antisymmetric, and/or transitive. Give a brief explanation of why the given relation either has or does not have each of the properties. (x,y) E R if and only if:
(1) x + y = 0
(2) x – y is a rational number (a rational number is a number that can be expressed in the form a/b where a and b are integers)
(3) x = 2y
(4) xy >= 0

Answers

Answer:

See the explanation

Explanation:

Rules to Remember:

If R is the relation on set A, then:

R is REFLEXIVE when if (a,a)∈R for every element a∈A

R is SYMMETRIC if (b,a)∈R whenever (a,b)∈R

R is ANTI-SYMMETRIC if (b,a)∈R and (a,b)∈R such that a=b

R is TRANSITIVE if (a,b)∈R and (b,c)∈R such that (a,c)∈R

1) x + y = 0:

R is NOT REFLEXIVE because x + x = 0 only when x = 0, not for all real numbers.

R is SYMMETRIC because x + y = 0 , then y + x = 0.

R is NOT ANTI-SYMMETRIC because 1 + (-1) = 0 and (-1) + 1 = 0 where 1 ≠ -1

R is NOT TRANSITIVE because 1 + (-1) = 0 and (-1) + 1 = 0, while 1 + 1 ≠ 0

2) x - y is a Rational Number:

R is REFLEXIVE because x - x = 0 where 0 is a rational number.

R is SYMMETRIC because x - y  is a rational number, then y - x = - (x - y) is also a rational number.

R is NOT ANTI-SYMMETRIC because 1 - 2 and 2 - 1 both are rational numbers where   1 ≠ 2

R is TRANSITIVE because if x - y is a rational number and y - z is a rational number, then x - z = (x - y) - (y - z) is also a rational number

3) x = 2y

R is NOT REFLEXIVE because x = 2x only when x = 0, not for all real numbers.

R is NOT SYMMETRIC because 2 = 2(1)  while 1 ≠ 2(2)

R is ANTI-SYMMETRIC because x = 2y and y = 2x, then x - y = 0 (As x = 2y = 2(2x) = 4x is only true when x = 0)

R is NOT TRANSITIVE because x = 2y and y = 2z,  then x = 2(2z) = 4z, which is not equal to x = 2z

4) xy ≥ 0

R is REFLEXIVE because xx = x² ≥ 0 which is always true

R is SYMMETRIC because xy = yx ≥ 0

R is NOT ANTI-SYMMETRIC because (2)(1) ≥ 0 and (1)(2) ≥ 0 where 1 ≠ 2

R is NOT TRANSITIVE because if x = -1, y = 0, z = 1, then xy ≥ 0, yz ≥ 0 but xz ≤ 0

Choose a problem that lends to an implementation that uses dynamic programming. Clearly state the problem and then provide high-level pseudocode for the algorithm. Explain why this algorithm can benefit from dynamic programming. Try to choose an algorithm different from any already posted by one of your classmates.

Answers

Answer:

Explanation:

The maximum weighted independent collection of vertices in a linear chain graph is a straightforward algorithm whereby dynamic programming comes in handy.

Provided a linear chain graph G = (V, E, W), where V is a collection of vertices, E is a set of edges margins, and W is a weight feature function applied to each verex.  Our goal is to find an independent collection of vertices in a linear chain graph with the highest total weight of vertices in that set.

We'll use dynamic programming to do this, with L[k] being the full weighted independent collection of vertices spanning from vertex 1 \to vertex k.

If we add vertex k+1 at vertex k+1, we cannot include vertex k, and thus L[k+1] would either be equivalent to L[k] when vertex k+1 is not being used, or L[k+1] = L[k-1] + W[k+1] when vertex k+1 is included.

\(Thus, L[k+1] = max \{ L[k], \ L[k-1] + W[k+1] \}\)

As a result, the dynamic programming algorithm technique can be applied in the following way.

ALGO(V, W, n) // V is a linearly ordered series of n vertices with such a weight feature W

\(\text{1. L[0] = 0, L[1] = W[1], L[2] = max{W[1], W[2]} //Base cases} \\ \\ \text{2. For i = 3 to n:- \\} \\ \\\text{3........ if ( L[i-1] > L[i-2] + W[ i ] )} \\ \\ \text{4............Then L[ i ] = L[i-1]} \\ \\ \text{5.........else} \\ \\ \text{6................L[i] = L[i-2] + W[i] }\\ \\ \text{7. Return L[n] //our answer.}\)

As a result, using dynamic programming, we can resolve the problem in O(n) only.

This is an example of a time-saving dynamic programming application.
