Use truth tables to determine whether or not the following arguments are valid: a) Either sales or expenses will go up. If sales go up, then the boss will be happy. If expenses go up, then the boss will be unhappy. Therefore, sales and expenses will not both go up. b) If the tax rate and the unemployment rate both go up, then there will be a recession. If the GNP goes up, then there will not be a recession. The GNP and taxes are both going up. Therefore, the unemployment rate is not going up. discrete math

5. Jason's bakery sells a variety of savoury packs. Jason decides to make only the following two pastry packs to streamline production as they have sold the best over a long period of time. - The Party Pack, which contains three pasties, two sausage rolls, and four pies - The Mini Pack, which contains three pasties, four sausage rolls, and two pies Let "x" be the number of Party Packs sold and "y" be the number of Mini Packs sold. Each day, Jason only bakes 18 pasties, 20 sausage rolls, and 20 pies to sell. a) Complete the table below: Savoury Pack Party Pack Mini Pack no. of Pasties b) Five constraints can be used to model this situation.

Exercise: Determine whether the following arguments is valid or invalid. 1. If I am happy, I do not eat too much. I eat too much or spend money. I do not spend money. Therefore, I am not happy. 2. If we serve tilapia, then Vanessa will join us for lunch. If Vanessa joins us for lunch, then Gilda will not join us for lunch. Therefore, if we serve tilapia, Gilda will not join us for lunch. Guide Questions: 1. In your own observation, what are the information to consider in justifying whether an argument is valid or not? 2. State in your own words on how to show that a given argument is valid or not. Reflection Recall a very significant childhood experience you have. Narrate it using series of propositions and explain why the argument is valid or not. Write your answer on your journal.

For people who fill the long income tax form with illegal deductions, every 6 out of 9 know it is illegal, and the remaining 3 out of 9 did it incorrectly because they are unfamiliar with the tax regulations. Among those who filled illegal deductions and know it is illegal, 75% will deny knowledge of the error. Among those who filled illegal deductions because of unfamiliarity, 100% deny knowledge of the error. If the filer filled out the form with illegal deductions and denies the knowledge of the error, what is the probability that the filer knows it's illegal?
Which of the following statements is CORRECT? One of the disadvantages of incorporating a business is that the owners then become subject to liabilities in the event the firm goes bankrupt. Sole proprietorships are subject to more regulations than corporations. In any type of partnership, every partner has the same rights, privileges, and liability exposure as every other partner. Sole proprietorships and partnerships generally have a tax advantage over many corporations, especially large ones. Corporations of all types are subject to the corporate income tax.
For the peing, the air traffic control system in the United States is run by the federal government. Several groups disagree with this and would like to privatizu in deciding if, indeed, delays in the U.S. are "too common" might be to compare the flight delay information from the U.S. and other nations. . air traffic control system. Among the arguments given for privatization is that flight delays are much too common in the United States. A first step You have in front of you the following chart, which summarizes the information from three samples of flights from the past six weeks. One of the samples is composed of domestic U.S. flights, one is composed of domestic Canadian flights, and one is composed of domestic British flights. The information recorded for each flight is the time (in minutes) that the plane was late to the arrival gate. (If the plane was early, the time recorded was negative.)

First National Bank employs three real estate appraisers whose job is to establish a property's market value before the bank offers a mortgage to a prospective buyer. It is imperative that each appraiser values a property with no blas. Suppose First National Bank wishes to check the consistency of the recent values that its appraisers have established. The bank asked the three appraisers to value (in $1,000s) three different types of homes: a cape, a colonial, and a ranch. The accompanying table shows the results. Assume that values are normally distributed. (You may find it useful to reference the g table.)
