Can someone please help me with these three easy questions please? Thank you! SHOW ALL WORK!!

THIS IS MY DATA FROM MY LAB EXPERIMENT. I JUST NEED FOR YOU TO FIND THE ANSWERS TO THE ABOVE QUESTIONS WITH WORK SHOWN!

Procedure

Put on your safety glasses and gloves (provided in your safety box).

Turn on the scale by pressing the button labeled "0/T". If your scale does not turn on, you may have to remove the battery cover and remove a small strip of plastic from the battery housing. Once the scale is on, press the "0/T" button a second time to zero the scale. Make sure that the units are in grams (g). If not, press the M button until the units displayed are in grams.

Place a weigh boat on the scale and record the mass in Table 2. Zero the mass of the weigh boat by pressing the "0/T" button. Your scale should now read 0 g.

Add 2.0 g of CaCl₂ to the weigh boat. Record the mass in Table 2. Set this sample aside, and let it sit exposed to the air (but otherwise undisturbed) for 24 hours. Complete Steps 3 - 23 while you wait.

Place a 250 mL beaker on the scale and zero it.

Add 2.0 g of CaCl₂ to the beaker. Record the exact mass of the powder in Table 1.

Remove the beaker from the scale. Use a 100 mL graduated cylinder to measure and pour 50 mL of distilled water into the beaker and mix with the stir rod until all the CaCl₂ has dissolved.
Note: This is an exothermic process, so the beaker may become warm.

Place a 50 mL beaker on the scale and zero the scale.

Add 2.5 g of K₂CO₃ to the 50 mL beaker. Record the exact mass of the powder in Table 1.

Remove the beaker from the scale. Use the 100 mL graduated cylinder to measure and pour 25 mL of distilled water into the 50 mL beaker. Mix with the stir rod until all the K₂CO₃ has dissolved.

Rinse the stir rod with water.

Add all of the K₂CO₃ solution to the beaker containing the CaCl₂ solution. It is important that all of the K₂CO₃ is added to the beaker. To ensure this, rinse the 50 mL beaker with up to 5 mL distilled water, and pour the rinse in the CaCl₂ solution.

Using the stopwatch to keep time, stir the solution with the stir rod for four minutes. Then, allow it to sit for 15 minutes. This will allow sufficient time for the chemical reaction to occur.

Rinse the stir rod with water.

Place a piece of filter paper on the scale and record the mass in Table 1.

Place a watch glass on the scale and record the mass in Table 1.

Fold the filter paper in half and in half again so that it resembles a triangle with one arched side.

Pull apart one fold of the filter paper so that three sides of the filter paper remain together, with one side making up the other half of the funnel shape (Figure 5).

Hold the funnel over a sink or any sized container. Place the paper into the funnel and use a pipette to drip 5 mL of distilled water around the edges of the filter paper. This will prevent the filter paper from rising up out of the funnel.

Rest the funnel on top of the Erlenmeyer flask.

After 15 minutes has passed, swirl the beaker and slowly filter the solution (that you created in Step 9) from the 250 mL beaker through the filter paper. Additional distilled water may also be used to transfer any remaining solid into the filtration apparatus.

After all the solution has been filtered, use the pipette to rinse the filter paper with approximately 5 mL of isopropyl alcohol to aid the drying process. Allow the isopropyl alcohol to completely drip through the filter before removing filter paper from the funnel.

Carefully remove the filter paper. Unfold and place it precipitate-side up onto the pre-weighed watch glass. Be sure not to lose any precipitate during this transfer.

Allow the precipitate to dry, undisturbed, for at least 24 hours. Determine the mass of the product recovered by re-weighing the system and subtracting the weight of the filter paper and watch glass. Record your data in Table 1.

Re-weigh the sample of CaCl₂ that was allowed to sit exposed for 24 hours. Subtract the mass of the weigh boat and record the mass and your observations in Table 2.

TABLE 2 IS NOT IMPORTANT IN SOLVING THE QUESTION AS IT JUST ASKS FOR MY OBERVATION OF CaCl₂ AFTER 24 HOURS. ALSO TO FIND THE ACTUAL YIELD, YOU WOULD HAVE TO FIND FIRST THE PERCENT YIELD AND THEORTICAL YIELD.

Dell technologies agreed on a $63bn acquisition of EMC Corporation in 2016. It was one of the largest tech deals in history. The merger makes Dell Technologies the leading provider of storage systems, second in servers, and third in PCs. Consider the press release below: “ AUSTIN, TEXAS , SEPTEMBER 7, 2016 - Dell Technologies today announced completion of the acquisition of EMC Corporation, creating a unique family of businesses that provides the essential infrastructure for organizations to build their digital future, transform IT and protect their most important asset, information. This combination creates a $74 billion market leader with an expansive technology portfolio that solves complex problems for customers in the industry’s fast-growing areas of hybrid cloud, software-defined data center, converged infrastructure, platform-as-a-service, data analytics, mobility and cybersecurity. Dell Technologies serves 98 percent of the Fortune 500 and comprises several market leading businesses.

Michael Dell, chairman and CEO of Dell Technologies, said, "We are at the dawn of the next industrial revolution. Our world is becoming more intelligent and more connected by the minute, and ultimately will become intertwined with a vast Internet of Things, paving the way for our customers to do incredible things. This is why we created Dell Technologies. We have the products, services, talent and global scale to be a catalyst for change and guide customers, large and small, on their digital journey." Dell Technologies blends Dell’s go-to-market strength with small business and mid-market customers and EMC’s strength with large enterprises and stands as a market leader in many of the most important and high-growth areas of the $2 trillion information technology market, including positions as a “Leader” in 20 Gartner Magic Quadrants and a portfolio of more than 20,000 patents and applications. Jamie Dimon, Chairman and CEO, JPMorgan Chase, commented, “Financial services is one of the first-movers in embracing technology to better serve our customers, and the next wave of digitalization continues a trend that’s been occurring my whole lifetime. As one of the world’s biggest users of Dell and EMC, we spend approximately $9 billion a year on technology, including infrastructure as well as cloud computing, big data analytics and cybersecurity. We make sure we spend wisely and select our partners very carefully. I’ve known Michael Dell for 30 years. He’s top notch, ethical, and deeply cares about everyone he works with – both internally at his company and across the industry. I'm thrilled for Michael and the new company, and we are eager to see everything they create in the future.” Marc Benioff, Chairman and CEO, Salesforce, added, “Salesforce’s partnership with Dell and EMC has been instrumental in pushing innovation across the industry. Michael is an incredible visionary and one of the most important leaders in our industry. He has been an amazing partner contributing to our success. Now with Dell Technologies, he is once again reshaping the technology industry." Tim McGrath, President and CEO of PC Connection, Inc., commented, “Our relationship with Dell has grown tremendously in the past six-plus years.

Hotdogs – The World’s Greatest Cost Effective Wholesome Nutritious Food
Due to world food supply scarcity and the burgeoning populations of the world’s countries, your hot stand business is
globalizing to satisfy the world’s desire for a cost effective wholesome nutritious food source. Market studies have
shown that tens of billions of people are craving for the eponymous hotdog which will result in a huge number of hotdog
sales from hotdog stands. You need to develop a program that tracks the activities of all the hotdog stands.
HotDogStandsClass
Define a class named HotDogStandsClass.
This class has the following for private member instance variables:
• Hotdog stand Identification
Each stand should have a unique identification
• Stand Location
A string that is the address of the stand which includes street, city and country.
For examples:
12 Deepika Padukone Ci, Bangelore, Karnataka 67089, India
1038 West Nanjing Rd, Westgate Mall, 8th Floor, Shanghai, Shanghai 200041, China
123 Jennifer Dr, UTD Food Court, 2nd Floor, Richardson Texas, 66666, USA
• Cost per hotdog
Cannot be negative, must be 0 or greater.
• Total Hot Dogs Sold Across All Stands
Cannot be negative, must be 0 or greater.
• Hotdogs Inventory Amount
The lowest value the inventory can be is 0. Negative inventory amounts do not make sense.
• Hotdogs Sold Count
This contains how many hot dogs this stand has sold since the stand object was created.
The HotDogStandsClass Class must include the following methods
• A constructor with parameters that sets all the instance values
• Accessor (Getter) and Setter methods that are required for all private member instance variables
• hotDogsBuy(n) method
• The method will be invoked each time someone (your main method test driver) wants to buy some hotdog(s).
• Has a parameter (n) that indicates the requested amount of hotdogs to be bought
• If the inventory is 0, the method should display a message that there are no more hotdogs left to be sold.
The method uses the amount of the hot dogs requested to:
• Increase the hog dogs total number sold for all the stands by the hotDogsBuy(n) parameter amount
It must be accessible to all the HotDogStandsClass objects.
• Increase the tracked hot dogs sold by the appropriate numberfor each stand
• Decrease the hot dog inventory by the appropriate number
• This method should be intelligent regarding the inventory.
The lowest value the inventory can be is 0. Negative inventory amounts do not make sense.
If the buy amount is more than the inventory, the class should state the number of hotdogs in inventory and
state to retry a buy.
If inventory amount is 0, the class should state that it is out of hotdogs and to try again later.
hopefully before a buy retry a stock inventory will be done.
• a stockInventory(n) method that is used to add inventory
Has a parameter (n) that indicates the requested number of hotdogs to be stocked

main()
This main program has the following:
The main program must create and use at least three hot dog stand objects of the HotDogStandsClass.
Write a main() test driver, a concept that is demonstrated in the book, to test the HotDogStands program. The main
test driver must test all paths of the logic flow of the program and conditions of the program to validate program
correctness.
Do not use any interactive prompts, unit test the HotdogStandsClass by coding in test scenarios in the main program
which will act as a test driver.
The main unit test driver must display information that indicates what is being tested with the test values being used
and after perfoming the hotdog stand operatiomn will display the state of the HotDogStandClass.
To accomplish this display of the class state, you should develop an overloaded stream output operator that displays a
well formatted string of object state (contents) that is well suited to being displayed using cout.
The output must be well formatted and readable to the user running the program. The main test unit driver does not
have to output if the test passed or failed, just what is being tested in the object of the class for each test and the class
state using the overloaded stream output operator (<<).
Use the following code to pause the screen:
#include <stdio.h>
:
cout << "Press the enter key to continue..." << endl; cin.ignore(); cin.get();
There is a system dependency that may require hitting the key twice for correct behavior.
Example:
HotDogStandClass hotdogstand1;
cout << “ buy 20 hot dogs “ << endl;
hotdogstand1.buy(20);
cout << hotdogstand1 << endl;
cout << “Press enter to continue”; cin.ignore(); cin.get();
You will lose points if the main function does not do comprehensive path testing of the program.
Before the program ends, the main part should display the total amount sold and display the final states of each of the
objects of the HotDogStandsClass.
The program must hold the screen for each unit test so that the class information can read.
Your program must use the class specification and class implementation design paradigms.
Therefore, you will have multiple files to upload for submittal to the eLearning system:
main.cpp
HotDogStandsClass.h
HotDogStandsClass.cpp

Estimate how many deaths there are annually from tornado and drowning in the United States. Provide an actual number in your answer and explain statistically how you came to that answer.

Info:

DROWNINGS:

From 2005-2014, there were an average of 3,536 fatal unintentional drownings (non-boating related) annually in the United States — about ten deaths per day.¹ An additional 332 people died each year from drowning in boating-related incidents.

TORNADOS:

The following scenarios are based on actual returns and situations that have occurred in this years VITA program. The responses provided here would be similar to those you would provide to actual taxpayers in the event a similar situation would occur.

Scenario

Inez Sanchez, age 49, ITIN # 933-12-1987 is married but has been separated from her husband since March 3, 2017. She is a housekeeper for Acme Hotels Inc. She has four daughters, all born and raised in the U.S. who lived with her the entire year who she fully supports. No one had any health insurance for the entire year

Name Date of Birth Social Security Number Earnings

Polet Sanchez 09/09/2006 454-11-2222 $0

Jessica Sanchez 07/07/2004 453-11-2222 $0

Stephanie Sanchez 05/05/2002 452-11-2222 $0

Juanita Sanchez 03/03/1995 451-11-2222 $8000

For legal reasons, she tells you that she wants to file a paper return. She also wants her refund mailed to her.

Inez’s Refund for 2019 was $4,600.

After completing Inez’s return, she mentions to you that many of her friend’s and co-workers who make about the same amount of money and have the same number of children got almost double of what she is getting?

Obviously, one of the major reasons is that she has an ITIN number and not a social security number which does not make her eligible for EIC. Another reason is because she has a child who is over 24 and makes more than $4250. Lastly she has a child who turned 17 in 2019 and is no longer eligible for the child tax credit

As usual the taxpayer is upset and believes that the return was not completed correctly. As the tax preparer or quality reviewer, your job is to explain to the taxpayer why your work is correct and why this changed occur

In the preparation process, all UIW-VITA procedures were followed and the results of your return are 100% accurate.

Instructions

For the purposes of this scenario, you must explain to Inez why her refund is the way it is. As the tax preparer or quality reviewer, your job is to explain to the taxpayer why your work is correct and why this return resulted in the refund that it did. Remember, you are dealing with a taxpayer who is unhappy with your work. For this assignment, you are not required to re-explain to me the results of the return again. Rather, I am looking for a procedure you would use to assure the taxpayer the result of your work are accurate. Remember, all of the policies and procedures that were used in the preparation process. Be creative.

Assignment 4.2 Beef Demand Model
A meat packing company hires you to study the demand for beef. The attached data are
supplied. Complete the following tasks, then open the quiz “4.2 Beef Demand” and
complete it.
1. Estimate the demand for beef as a function of the price of beef, the price of pork,
disposable income, and population. Label this as Model 1. Which independent
variables have a significant impact on the demand for beef?
2. The coefficient for the price of beef indicates that a one-dollar increase in price
leads to how large a decrease in quantity demanded?
3. Estimate the demand for beef as a function of the price of beef, the price of pork,
and per capita disposable income (per capita disposable income=[disposable
income/population]; you have to create this variable from the data). Label this as
Model 2. Which independent variables have a significant impact on the demand
for beef?
4. Which Model fits the data better? Comment on why, using statistics from the
regression model.
5. The meat packing company gives you the following assumptions: Price of
beef=$2; price of pork=$2.50; disposable income=$1,000,000; and
population=225. Given this information, use model 1 to complete the following:
a. Estimate of beef demand and a 95% confidence interval around this
estimate.
b. Estimate total revenue
c. Estimate the following elasticities: Price elasticity, Cross elasticity (that
is, elasticity with respect to Pork price), income elasticity, and population
elasticity.
d. Should the meat packing company increase or decrease the price of beef?
Why or why not?
