Complete this assignment and submit it to the dropbox by the required due date and time.  Most students use Microsoft Excel to complete the problems and attach the answers.  Other students have scanned their answers, and sent it as attachment.1. The Alibi Restaurant is normally open for business until 8:00 P.M. Recently, business has been getting better during the time period just before closing, and the manager is attempting to determine the viability of remaining open until 9:00 P.M. She estimates her additional costs for the extra hour as follows:Labor $75Heat, Light, and Gas $12Variable cost of food, beverage, etc. 40% of salesa. What additional sales are necessary for the manager to break even exactly on the extra hour of opening?b. If the manager were able to obtain $280 in sales volume for the extra hour, what income could be applied to normal overhead expenses?2.  A restaurant’s income statement shows the following cost and sales structure:Sales $450,000Fixed Costs $135,000Directly Variable Costs $120,000What must the semivariable cost figure be if the restaurant is to show a profit of $30,000?3. In Erphalene’s Restaurant, fixed costs are 30 percent of sales, and directly variable costs are 25 percent. What percentage of sales should semivariable costs be if the restaurant is to show a 10 percent profit?4. A restaurant selling hamburgers employs only one cook. During the peak lunch hour, the cook is able to produce 120 hamburgers per hour. During the slack afternoon period, he produces only 30 hamburgers per hour. If each hamburger sells for $0.60 and the cook is paid $8.00 per hour, calculate the labor cost per hamburger for one hour during each of the two periods described.PLEASE READ FIRST CH 18 HERE!

The probability of an event can be determined in theory as well as in practice. In this project, you will use the formulas and methods in your readings to determine the theoretical probability. You will then conduct an experiment to see if the outcomes match what you expect to find with the theoretical probability.   In this project you will: be able to calculate and interpret probability be able to analyze and compare theoretical and experimental probabilities   To complete this project you will: Complete the Probability Report Worksheet to guide you in writing your APA report. Be sure to show all work! Complete a 2-page, double-spaced, APA-formatted report. In the report you need to present your findings and explain your conclusions on experimental and theoretical probability.  Thoughts to include in the report include: How are theoretical and experimental probability different? Why might the theoretical probability not match the experimental probability? Be sure to cite your sources for the questions that require sources.

Calculate both problems first. then answer three questions below after. Keep it simpleQUESTION 20Macroeconomic Information for Mexico:2020 Q2 GDP (in 2020 Q2 pesos)    4.97 trillion pesos2020 Q1 GDP (in 2020 Q1 pesos)    6.09 trillion pesos2020 Q2 GDP (in 2015 pesos)    3.76 trillion pesos2020 Q1 GDP (in 2015 pesos)    4.54 trillion pesosCalculate Mexico’s real GDP growth rate between the first and second quarters of 2020.(Enter your answer in percent form, rounded to one decimal place, without the percent sign.  For example, if your answer is 0.12345, enter 12.3.)QUESTION 21Macroeconomic Information for Mexico:2020 Q2 GDP (in 2020 Q2 pesos)    4.97 trillion pesos2020 Q1 GDP (in 2020 Q1 pesos)    6.09 trillion pesos2020 Q2 GDP (in 2015 pesos)    3.76 trillion pesos2020 Q1 GDP (in 2015 pesos)    4.54 trillion pesosCalculate Mexico’s inflation, using the GDP deflator method, between the first and second quarters of 2020.(Enter your answer in percent form, rounded to one decimal place, without the percent sign.  For example, if your answer is 0.12345, enter 12.3.)QUESTION 22Based on your answers from #20 and #21, use the aggregate supply/aggregate demand model to explain what is happening in the Mexican economy.  Your answer should indicate which curve is moving and in what direction, as well as how you know this.QUESTION 23Based on your answers from #20 and #21, is Mexico’s short-run aggregate supply curve flat or steep?  How do you know?QUESTION 24What fiscal policy do you recommend that Mexico use to resolve the problem you identified in #23?  Be as specific as possible.  Why?

One paragraph (only describing data) ( it do not need to write intro and conclusion, Just describing a graph) 1. Describe the topic of the table (table name, topic, location, units, years etc.) 2. Describe a general trend. 3. Describe a specific/sub-trend 4. Describe outliers/unique trends Life expectancy at birth in relation to health spending per capita Graph ( Health at a Glance 2017 – graph 3.3 page 49)

Write a statistical report based on the sample of 50 freight trains in United States. The project consists of two files (1) The sample data are provided in the Excel file under “data” sheet. (2) The results should be reported and analyzed/explained in an Microsoft Word file (report) Your report should have an introduction part that provides brief background information on the freight trains. Then start present your sample results to cover all topics listed below. You should present all results in a logical and organized way. A list of numbers and charts will not earn high scores. (1) A stem-and-leaf plot (with proper keys) to present all sample data (2) A bar graph to summarize the sample data by display a frequency distribution (with proper classes and details) (3) Centers of the sample data – mean and median: discuss in general what they measure and what example results show. (4) Measure the variation of the sample data – standard deviation and range: discuss in general what they measure and what example results show. (5) Discuss if there are any outliers in the sample in a quantitative way (e.g. IQR measure). (6) Explain the meaning of confidence interval for a pouplation mean and present the 90%-confidence interval from this sample. In the end, use a paragraph to close the report.
