For this discussion, you will work in groups to solve for a in the oblique triangle ABC; AB = 30; AC = 15 and angle B = 20 ∘ For your initial post, use the Canvas Equation Editor to type out the two equations substituting the numbers from the diagram.First, type out the Law of Sines set of relationships.Next, type out the most appropriate version to use the Law of Cosines for this solution.Post both equations and make a prediction of which method will be easier to use in finding a solution and why you think that is the case.Make your initial post by the fourth day of the module week. You must make your initial post before you can see the posts of your classmates.Solve & ReplyNow, for your first reply, solve for a using the Equation Editor. If your birthday is between:January and June, use the Law of CosinesJuly and December, use the Law of SinesRemember, post your solution and your step-by-step work to your initial post- not someone else's. my birthday is in july so I need a solve for sines

To complete this assignment, use the Excel file, “Data for Assignment 1,” posted on Blackboard in the Excel Assignment folder on the “Assignments” tab.It is preferred that students work in pairs on assignments, with one assignment submitted per pair; both students in a pair will receive the same grade. It is strongly recommended that both students actively participate in preparing the assignment. If, instead, partners choose to split the assignment (with each being responsible for different parts of the assignment), be aware than one person’s poor/non-completion of his/her portion is NOT an acceptable reason for submitting the assignment late. You may work with a student in the Monday section; if you do, please note that when you upload your assignment. (The Wednesday assignment is due before the Monday assignment; if you work with a Monday student, your assignment is still due on 9/23/2020.)At the completion of your assignment, you should have one workbook with four tabs (the original three tabs + one worksheet you have created). Name the file as follows: OurNamesAssign1.xlsx (or NamesAssign1.xls), where you replace OurNames with your first initials and last names. Your name(s) must be a part of your file name. Upload your completed Excel document to Blackboard on the assignment page.INSTRUCTIONS – READ CAREFULLY:When it is appropriate to show decimals, you should show 2 decimal places; use of decimal places should be consistent within a column (or variable). Use cell referencing in all formulas, and use functions that we have discussed in class whenever possible; a significant part of your grade is dependent on your use of appropriate cell referencing and use of functions.TIPS: Make it easy to locate all requested information. You can use bold or another font color or try using the paint can to fill the cell with color ( page1image3599999136) Use column/row titles to describe thedata included. Use column and row columns to describe the data included. To receive full credit, you will need to follow all instructions.Question 1 (27 points) Using the Fourth Quarter 2019 California Hospital Quarterly Financial and Utilization data (thefirst tab in the “Data for Assignment 1”), copy the San Diego and Los Angeles County hospitalspage1image3600044112 page1image3600044400 1PH 307 Fall 2020to a new worksheet within this workbook. (Copy the rows holding the variable names and Los Angeles and San Diego County hospitals as described in class; do not copy the whole worksheet.) Name this tab “San Diego and Los Angeles.” Sort this worksheet by county. Remove any hospitals where the results of your calculations equal “#DIV/0!.” (To make the data easier to work with, I suggest that you hide columns that you will not need to answer the question.)Calculate the net inpatient revenue (est.) for each hospital located in San Diego County and Los Angeles County. (Hint: You will need to refer to the OSHPD documentation to determine how to calculate the net inpatient revenue.) What are the mean and median net inpatient revenue (est.) for San Diego and Los Angeles Counties combined? In a new column, use the appropriate function to recode the net inpatient revenue for each hospital as follows: 1) 0 if the net inpatient revenue is less than $25,000,000; 2) 1 if the net inpatient revenue is equal to or greater than $25,000,000. Calculate the cost-to-charge ratio for each hospital located in San Diego County and Los Angeles County. (Refer to the OSHPD documentation to determine the correct formula.) Set up this worksheet as follows:1) Include a header with your names and the date the assignment is due in the top right corner;2) Set the titles to repeat at top and the facility number and name to repeat at left; 3) Have the gridlines print. Show only the facility number, facility name, county name, type_control, the columns used in the calculation, and the columns holding the information you calculated. Question 2 (23 points) The data on the “Hysterectomy” tab is a random sample of all hysterectomies performed in theUS in 1992.Using this data, create a frequency table and calculate relative frequency, cumulative frequency, and cumulative relative frequency for the age intervals 15-24, 25-34, 35-44, 45- 54, 55-64, 65-74, 75-84. To get credit on this question, you must use functions to calculate the frequencies; sorting the ages will not give you credit. Calculate the mean age of hysterectomies. page2image3584244096 2PH 307 Fall 2020 C. What is the percentage of women under the age of 35 who have had a hysterectomy?Please place parts B and C directly below the frequency table you have created.D. Set up this worksheet as follows:1) Portrait orientation;2) Include a header with your name and the date the assignment is due in the top right corner;3) Have the gridlines print.Question 3 (25 points) You work as a data analyst for a health insurance company. Your firm is considering twoalternative plans for insuring employees of a company during the upcoming year.PlanA: Yourcompanywouldpay80%ofchargesforallservicesreceivedduringtheyearafter each employee pays a $650 annual deductible.Plan B: Your company would pay 75% of full charges, with no deductible or patient copayment.Last year’s claims by the employees of the company you are insuring are contained in the worksheet titled (Insurance Question) in the “Data for Assignment 1” workbook. There are three variables in this file: Total Charges = last year’s $ charges for medical services, Age = age of the individual, Sex = sex of the individual. You have been asked to analyze these plans to estimate next year’s payout under each alternative, using the assumption that charges will increase 8% next year over last year’s values.Please answer the following questions:Show each individual’s charges with the 8% increase. Show each individual’s charges under Plan A. Show each individual’s charges under Plan B. What is the total payout under each alternative? What is the total cost for females and for males under each of the plans? What is the average cost per female and per male under each of the plans? page3image3584554496 3PH 307 Fall 2020NOTE: Remember that your firm will pay nothing under Plan A for someone who incurs less than $650 in charges during the year (i.e., the employee’s charges do not exceed the $650 deductible).C. Set up this worksheet as follows:1) Landscape orientation;2) Include a header with your name and the date the assignment is due in the top right corner;3) Have the gridlines print.https://blackboard.sdsu.edu/bbcswebdav/pid-5803973... that's the dats let me know if u cant see that link
