Programming

Write a program that initializes an array with 10 random integers between 0 and 100 and then prints exactly 5 lines of output. These 5 lines should contain:

• The elements in the array, as printed by Arrays.toString()
• Every element at an even index
• Every even element
• All elements in reverse order
• Only the first and last element

Initially write your code so that you initialize the array in the main method. You will not ask the user for any input, but will use Math.random to generate 10 random numbers between 0 and 100 to put in the array.

As an example, if the array contained { 34, 82, 45, 92, 71, 1, 18, 20, 52, 99 }, the five lines would be:

Array: [ 34, 82, 45, 92, 71, 1, 18, 20, 52, 99 ]

Elements at even index: 34 45 71 18 52

Even elements: 34 82 92 18 20 52

Reverse order: 99 52 20 18 1 71 92 45 82 34

First: 34 and Last: 99

If you complete all the steps above, please go back and move your code that fills the array into a separate method within your class. The method will create the array, fill it with the random numbers, and then return it to the caller.

Remember to use good coding style, and javadoc comments where appropriate.

NOTE: Please read instruction and example carefully while writing java code. Please include JAVADOC too. Thank you in advance.

Are there gender differences in the time spent using on social media? A time-tracking software was used to determine the average time on social media websites in a random sample of 31 men and 31 women. Men, on average, spent 49 minutes per day on social media websites, with the standard deviation of 25. Women, on average, spent 52 minutes per day on social media websites, with a standard deviation of 18. Use α=0.05.

Your task in this paper is to identify FIVE of the your most endearing important personal values and identify how they both guide you and hinder you in your critical thinking. So as you can tell there are two parts to this assignment (each with it's own heading to clearly identify you have completed this assignment): 1) identify your values, and then 2) identify how they both guide you and hinder you in your critical thinking.

Case Application : Training Better Managers…Now at Walmart

Walmart, the world’s largest retailer, is a mega-business with more than 11,700 retail units in 28 countries and approximately 2.3 million associates around the world. That’s a lot of employees to manage! Its most recent annual revenues were more than $485.3 billion with profits of more than $13.6 billion. Because of its position as the United States’s largest private employer, Walmart often finds itself at the center of controversy over employee-related issues, from sick day policies40 to wage concerns.41 However, in 2016, the company created its Walmart Academy training program, a program intended to help those employees in lower-level management positions be more successful in their careers. Currently, there are some 100 of these academies across the United States. Since its inception, more than 150,000 store supervisors and department managers have gone through the weeks-long training.42

What does the training include? Topics cover advanced retail skills, including merchandising, ordering, and inventory control, plus managerial skills, including better communication and motivating employees. All management training is designed with the goal of helping transform the in-store shopping experience into a consistently positive one. As the industry faces increasing competitive pressures from Amazon and other online sellers, brick-and-mortar retailers are being forced to provide customers with something that makes the customer want to come to their store again and again. For Walmart, this means that if the company wants to create a more pleasant in-store shopping experience, it needs a well-trained and engaged workforce. That starts with the managers who, in turn, take that focus back to training their employees to be attentive to customers. Walmart thinks this effort is so vital that it has spent $2.7 billion (yes, that’s billion!) on employee training and raising employee wages. That’s a significant investment. However, there are companies that evidently don’t focus on training managers as Walmart does. Here are some startling statistics43:

· 26 percent of new managers feel they’re unprepared to transition into management roles.

· 58 percent of new managers don’t receive any training to help them make the transition.

· 48 percent of first-time managers fail in that transition.

Considering the important role that managers play in employee motivation and engagement, investing in training like Walmart is doing, seems to be a good investment.

Discussion Questions

1. Why would a company want employees in lower-level management positions to be more successful in their careers? (Hint: Think efficiency/effectiveness and the four functions of management.)

2. What benefits and challenges do you see to a training program such as this?

3. Does an organization have an ethical responsibility to assist new managers’ transition into their positions? Why or why not?

A 62.5 kg skier is moving at 6.15 m/s on a frictionless, horizontal snow-covered plateau when she encounters a rough patch 4.00 m long. The coefficient of kinetic friction between this patch and her skis is 0.320. After crossing the rough patch and returning to friction-free snow, she skis down an icy, frictionless hill 3.35 m high.

A)How fast is the skier moving when she gets to the bottom of the hill?

BHow much internal energy was generated in crossing the rough patch?

Use Gauss's law to prove that the electric field outside any spherically symmetric charge distribution is the same as if all of the charge were concentrated into a point charge at the center of the sphere. Then use Gauss's law to prove that the electric field inside a spherically symmetric conductor carrying a net charge on its surface is zero.

Ok the question asks

Know the definitions for the following terms(writing the equation/formula only is not enough):

Magnetic Flux

Faraday's Law

Lenz's Law

It asks for all 3 and again just writing equation/formula is not enough.

Write a test program that prompts the user to enter 10 numbers and displays the mean and deviation, as shown in the following sample run:

Your program should contain the following functions:

// Compute the mean of an array of double values
double mean(const double x[], int size)
// Compute the deviation of double values
double deviation(const double x[], int size)

Write a test program that prompts the user to enter 10 numbers and displays the mean and deviation, as shown in the following sample run:

ex:

Enter ten numbers: 1.9 2.5 3.7 2 1 6 3 4 5 2
The mean is 3.11
The standard deviation is 1.55738

So this what I have:

#include <iostream>
#include <cmath>

using namespace std;

void displayVals(int vals[], int numVals, int sum);
void getVals(int vals[], int numVals);
double average(int sum, int numVals);
double stanDev(int vals[], double mean, int numVals);

int main()
{
   int numVals=10;
   int sum = 0;
   int vals[9];

   getVals(vals, numVals);
   cout << endl;
   displayVals(vals, numVals, sum);
   cout << endl;

}

void getVals(int vals[], int numVals)
{
   int index;
   cout << "Enter ten numbers :" << "\n";
   for (index = 0; index < numVals; index++) {
       cout << index + 1;
       cin >> vals[index];
   }
}

void displayVals(int vals[], int numVals, int sum)
{
   int index;
   for (index = 0; index < numVals; index++) {
       cout << index + 1;
       cout << vals[index] << ".\n";
   }

   cout << endl;
   cout << "The mean is ";
   cout << average(vals, numVals, sum) << ".\n";

   cout << endl;
   cout << "The standard deviation is: ";
   cout << stanDev(vals, numVals, sum) << ".\n";

}

double average(int sum, int numVals)
{
   double dsum = (double)sum;
   double dnumVals = (double)numVals;
   return dsum / dnumVals;
}

double stanDev(int vals[], double mean, int numVals)
{
   double sum = 0, dVals = 0, value = 0, variance = 0;
   for (int i = 0; i < numVals; i++)
   {
       dVals = (double)vals[i];
       value = (dVals - mean)*(dVals - mean);
       sum += value;
       variance = sum / (numVals);
   }
   return sqrt(variance);
}
