Lucy gets home at a random time between 5:27 and 6:32 each evening, and watches the next news show that’s on. Network 1 airs news shows every half-hour (at 5:00, 5:30, 6:00, etc.); network 2 airs news shows at 5 minutes past each half-hour. Lucy will not start watching a show that’s already in progress.

(a) Let Ni be the event that Lucy ends up watching the news on network # i tomorrow, for i ∈ {1, 2}. Find P(Ni).

b) Find the expected amount of time that Lucy will have to wait to watch the news tomorrow.

5. Write a program that prints all numbers between 27 and 78, one number per line.

6. In questions 6,7 the following list is used: [1,2,5,6,3,77,9,0,3,23,0.4,-12.4,-3.12]

7. Using “for” loop, write program that finds the smallest number in the list.

8. Using “for” loops, calculate arithmetic mean of all numbers in the list. Do not use built-in function in Python.

9. For this question envision you are creating a dummy alert to help the doctor determine if patient needs a mammogram or not: Ask the user to answer the following questions:

• "What is your patient’s gender? Please answer F for female, M for male " and store it in a variable "gender".

• "What is your patient’s age? " store it in a variable "age"

• "Does your patient have family history of breast cancer? Please answer with True or False " store it in a variable name "history" The program should display the following alert messages based on conditions:

• If patient is female and over 40 the system should alert the doctor to "consider ordering mammogram”

• If the patient is female but younger than 40 the program should go to next step and consider patient family history to determine if mammogram is recommended. If patient has family history of breast cancer the program should display a message "consider mammogram because of family history". If not just display "my not need mammogram" • In any other case the alert should say "no mammogram order recommended". Suggestion: Attention to the variable types when you input and compare.

Variance Company produces Chemical Y. It budgeted to produce 10,000 gallons of Chemical Y in fiscal year 2006. It actually produced 11,000 gallons. The production process for Chemical Y has two principal ingredients, Mystery Material M and labor. To produce 1 gallon of Chemical Y under budget requires 10 gallons of Mystery Material M @ $3/gallon and .5 labor hours @$20/labor hour. During 2006, it spent $346,500 to purchase 99,000 gallons of Mystery Material M that Variance Company used in production. Its actual total labor costs were $115,000 and it used 5,000 hours of labor

Is Job Satisfaction going down? In the past ten years, several authors have stated that people are miserable in their jobs and have become increasingly unhappy over time. Job satisfaction scores from participants in the General Social Survey (GSS) in 1975 and 2006 were studied. Higher scores indicate greater satisfaction, with 2.5 being a neutral score. Here are summaries of scores for 1975 and 2006:

a) Run a test of significance to see if there is a significant decrease in mean scores from 1975 to 2006? Be sure to clearly state the null and alternative hypotheses, clearly label and state the value of the test statistic, clearly label and state the value of the P-value and clearly state the conclusion of the test in the context of the problem.

b) The paper from which the data came includes several years from 1972 to 2006. 1975 was the year with the highest mean score. What, if any, effect does this information have on your assessment of whether job satisfaction has decreased over time?

What are the performance obligations in the contract?

Information need from Case 3 for the year end December 31, 2007 need for this question.

Total sales revenue: $639,111

Food operations sales revenue: $458,602 and Beverage operations sales revenue: $180,509

Average check for food and beverages: $9.59 Average check for food: $6.88 Average check for beverages: $2.71

In the case at the end of Chapter 3, you calculated the average food and beverage check for the 4C Company’s 84-seat restaurant in Year 2004. The restaurant was open for 52 weeks, 6 days a week for lunch, and 5 days a week for dinner. An analysis of sales checks indicated that the average turnover was 1.5 times for lunch and 1.25 times for dinner. Lunch contributes about 45 percent of total sales revenue and dinner, 55 percent. Total beverage sales revenue is 20 percent at lunch and 80 percent at dinner. a. Calculate the average lunch and average dinner checks for food and beverages.

This is how I think you solve the question. Is this correct?

Ave Lunch Check = (45% * $639,111) / (84 seats * 1.5 * 312days) = $7.3158 then of this $7.3158, 20% is from beverage sales and 80% is from food sales therefore:

Average lunch beverage check = $7.3158 * .2 = $1.46

Average lunch food check = $7.3158 * .8 = $5.85

Ave Dinner check = (55% * $639,111) / (84 seats * 1.25 * 260days) = $12.87586 then of this $12.87586, 80% is from beverage sales and 20% is from food sales therefore:

Average dinner beverage check = $12.87586 * .8 = $10.30

Average lunch food check = $12.87586 * .2 = $2.57

In 2021, the Westgate Construction Company entered into a contract to construct a road for Santa Clara County for $10,000,000. The road was completed in 2023. Information related to the contract is as follows:

Westgate recognizes revenue over time according to percentage of completion.

Required:
1. Calculate the amount of revenue and gross profit (loss) to be recognized in each of the three years. (Do not round intermediate calculations. Loss amounts should be indicated with a minus sign.)

Consider three possible taxes that would raise the same revenue: A) a property tax on the value of real estate, B) a per-unit tax on soft-drinks, and C) a sales tax on staple foods.

a. Rank the three taxes based on their economic efficiency in raising revenue. Explain. (You may refer to them by letter)

b. Explain why a policymaker might choose a different rank ordering of the three taxes when choosing which to implement.

1. Name three ways to identity which part of the Internal Revenue Code is relevant in a research project.
