The Upper Midwest of the United States has lagged behind the economic recovery enjoyed by much of the rest of the nation. With an economy built largely on the steel, lumber, agriculture, and manufacturing industries, local businesses were hit by the triple challenges of declining commodity prices, globalization, and automation. Countries such as China and Canada offer cheaper steel or lumber, crop prices have been falling, and many manufacturing jobs either were replaced by robots or moved to China, Southeast Asia, or Mexico. Finding thriving businesses in this region can be difficult, and one of the few standouts has been in the gaming industry.

A small group of Native American tribal leaders opened the Brown Bear casino about 30 years ago. The facility was built on tribal land. Initially started as a relatively small stand-alone casino, the complex has grown to include 2,000 slot machines, 25 blackjack tables, a bingo ball for 600 players, a convention center, a 400+ room hotel, three restaurants, and a golf course. Over the years it has become a destination location for those wanting to play golf, see shows, enjoy good meals, and gamble without having to travel all the way to Las Vegas to make it happen.

The Brown Bear casino complex is now a $50 million business headed up by a general manager, who in turn oversees 11 different department heads, such as the chief financial officer, head of security, director of gaming operations, and so on. These 11 leaders manage the 1,200 employees working at the casino, hotel, convention center, and golf course. Although the casino enjoyed strong growth during its first 20 years of existence, it has not recovered fully from the economic recession of 2007-2009. Many of the good-paying jobs in the area disappeared, and as a result the local population has become considerably smaller and older. Compounding this problem is the fact that the gaming industry is facing increasing competition for customers' entertainment dollars. The chief marketing officer has implemented a number of campaigns to bring more and younger customers into the casino and increase their average spend per visit, but so far these efforts have yielded negligible results.

Although the casino is the largest employer in the area, staffing and employee engagement have been chronic problems. Many long-term employees appear to be completely checked out at work, biding their time until retirement, and they go out of their way to disparage those who put in an honest day's work. Despite paying a competitive wage and the relative scarcity of good-paying jobs in the region, the casino averages 30 percent annual turnover, with some positions reporting turnover rates over 100 percent. Turnover is not only taking a toll on the employees who remain (as they often have to pick up the slack for those who leave), but it also has an impact on the casino s customer satisfaction and financial results. Newer and less experienced staff do not know how to handle more complex customer issues, and it costs the casino $1,000-$5,000 in recruiting fees for each new person hired. With 400 new staff being hired each year, these staffing fees are having a material impact on the company's bottom line.

The general manager has asked you to help reduce staff turnover, create a more engaged staff, in the hope that this will improve the casino's customer satisfaction ratings, and have a positive impact on revenues and profitability.

The sex of an organism is typically determined genetically, but environmental factors can also play a role. Scientists examined the roles of genes and environmental temperature in the sex determination of a lizard species. Individuals with a  ZW pair of chromosomes are always female (ZWf), while individuals with a  ZZ pair of chromosomes can be either male (ZZm) or female (ZZf). Scientists mated  ZWf or  ZZf females with  ZZm males and incubated the eggs produced in 20 clutches at temperatures ranging from  23°C to  36°C. When the young hatched, the scientists determined their sexes (Table 1). Among the eggs that did not hatch, the mortality of embryonic lizards was approximately the same for both males and females.

Table 1. Fraction of female progeny produced as a function of egg incubation temperature

(a) If a particular gene is located on the  Z chromosome of this lizard species,  describe why a lizard with a  ZWgenotype has a greater probability of expressing the recessive phenotype for the trait than a lizard with the  ZZgenotype does.

Question 2

(b) Using the template,  construct an appropriately labeled graph, including error bars, to represent the data in Table 1. Based on the data, compare the  ZZm×ZWf crosses and the  ZZm×ZZf crosses to  determine whether there is a significant difference between the two crosses in the fraction of female progeny produced at  24°C,  32°C, and  36°C.

Question 3

(c) For each cross,  describe whether genetics or temperature determines the sex of progeny produced from eggs incubated at  35°C. For each cross,  describe whether genetics or temperature determines the sex of progeny produced from eggs incubated at  24°C.

Question 4

(d)  Predict the effect of increasing global temperatures on the continued presence of the  W chromosome in this species of lizard. Scientists claim that, in this species, the  W chromosome is unimportant in sex determination. Instead, proteins that are encoded by a gene or genes on the  Z chromosome, and that are maximally expressed only at certain temperatures, are responsible for determining whether embryos will develop as females or males. Use the data to  support this claim.

Edgerron Company is able to produce two products, G and B, with the same machine in its factory. The following information is available.

The company presently operates the machine for a single eight-hour shift for 22 working days each month. Management is thinking about operating the machine for two shifts, which will increase its productivity by another eight hours per day for 22 days per month. This change would require $8,000 additional fixed costs per month. (Round hours per unit answers to 1 decimal place. Enter operating losses, if any, as negative values.)

I am working on creating a Broadcast Receiver. I am extremely new to Android development and Java. I added my code at the bottom. Whenever I press the button the app crashes. I'm assuming something is wrong with connecting the broadcastIntent() function. I appreciate any help :)

Here are the directions from my professor:

1. Create an empty project
2. Create a method in MainActivity.java which creates a Broadcast.

public void broadcastIntent(View view){
       Intent intent = new Intent();
       intent.setAction("my.CUSTOM_INTENT"); sendBroadcast(intent);
   }

3. Add a button to activity_main.xml and link it to this method.
4. Is it working? How can you test it? STOP
5. Create a Broadcast Receiver (accept defaults)
6. Add the following code to your receiver in onReceive() : (remember to comment out the auto generated exception!) what’s an exception?

Toast.makeText(context, "Intent Detected.", Toast.LENGTH_LONG).show();

7. Edit your manifest by adding the following as a child node of <receiver>

<intent-filter>
    <action android:name="my.CUSTOM_INTENT"></action>
</intent-filter>

8. RUN it

MY CODE:

<main activity>

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
    private Button mybutton;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button mybutton = (Button) findViewById(R.id.mybutton);
        broadcastIntent( );
    }

    private void broadcastIntent() {
        Intent intent = new Intent();
        intent.setAction("my.CUSTOM_INTENT");
        sendBroadcast(intent);
        }

7.26 LAB: Nutritional information (classes/constructors)

Given main(), complete the FoodItem class (in files FoodItem.h and FoodItem.cpp) with constructors to initialize each food item. The default constructor should initialize the name to "None" and all other fields to 0.0. The second constructor should have four parameters (food name, grams of fat, grams of carbohydrates, and grams of protein) and should assign each private field with the appropriate parameter value.

Ex: If the input is:

M&M's
10.0
34.0
2.0
1.0

where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is:

Nutritional information per serving of None:
   Fat: 0.00 g
   Carbohydrates: 0.00 g
   Protein: 0.00 g
Number of calories for 1.00 serving(s): 0.00


Nutritional information per serving of M&M's:
   Fat: 10.00 g
   Carbohydrates: 34.00 g
   Protein: 2.00 g
Number of calories for 1.00 serving(s): 234.00

The first FoodItem above is initialized using the default constructor
