Fuzzy Logic is used in artificial intelligence. In fuzzy logic, a proposition has a truth value that is a number between 0 and 1 inclusive. A proposition with a truth value of 0 is false and one with truth value of 1 is true. Truth values that are between 0 and 1 indicate varying degrees of truth. For instance, the truth value 0.8 can be assigned to the statement "Fred is happy.'' since Fred is happy most of the time, and the truth value 0.35 can be assigned to the statement "John is happy.'' since John is happy slightly less than half the time. The truth value of the negation of a proposition in fuzzy logic is 1 minus the truth value of the proposition. The truth value of a conjunction of two propositions in fuzzy logic is the minimum of the truth values of the two propositions. What are the truth value of the statements: (a) ``Fred and John are happy.'' and (b) ``Neither Fred nor John is happy.''

An airline has classified its customers as high-volume travelers (assumed to be business travelers) or low-volume travelers (assumed to be leisure travelers). Eight-five (85) percent are high volume travelers. If five people are randomly selected from a list of customers, what is the probability all are high-volume (business) travelers?

An economist wondered if people who go grocery shopping on weekdays go more or less often on Fridays than any other day. She figured that if it were truly random, 20% of these shoppers would go grocery shopping on Fridays. She randomly sampled 75 consumers who go grocery shopping on weekdays and asked them on which day they shop most frequently. Of those sampled, 24 indicated that they shop on Fridays more often than other days.The economist conducts a one-proportion hypothesis test at the 1% significance level, to test whether the true proportion of weekday grocery shoppers who go most frequently on Fridays is different from 20%.(a) H0:p=0.2; Ha:p≠0.2, which is a two-tailed test.(b) Use Excel to test whether the true proportion of weekday grocery shoppers who go most frequently on Fridays is different from 20%. Identify the test statistic, z, and p-value from the Excel output, rounding to three decimal places.Provide your answer below:test statistic = p-value =

Jay factored the 4 term polynomial x^3-9x\:+\:2x^2-18 x 3 − 9 x + 2 x 2 − 18 and decided that the complete factorization was (x+2\right) ( x + 2 ) \left(x^2-9\right) ( x 2 − 9 ) .Before turning in his paper, he checked his final factorization by multiplying out his factors and was sure that he had found the correct factors. When his teacher graded his paper, she marked his answer as incorrect, but gave him one more chance to show the correct factorization.a) What was Jay's mistake?b) Show/describe EACH step in factoring the 4 term expression correctly and completely:

A university with a high water bill is interested in estimating the mean amount of time that students spend in the shower each day. In a sample of 12 students, the average time was 5.04 minutes and the standard deviation was 0.96 minutes. Using this sample information, construct a 99% confidence interval for the mean amount of time that students spend in the shower each day. Assume normality. a) What is the lower limit of the 99% interval? Give your answer to three decimal places. b) What is the upper limit of the 99% interval? Give your answer to three decimal places.

Robert took $32 with him to spend on pizza and games for himself and his friends at Chucky Cheese. The price for each slice of pizza was $4. The price for each game was half the price of a slice of pizza. a) Sketch the graph that represents the situation and label the intercepts with the real world items you are comparing. Use one axis to represent the number of slices of pizza and the other axis to represent the number of games. b) What do the intercepts and the solutions of your graphed function mean in context of the problem? Explain both intercepts.c) If Robert spends his money on both pizza and games, give an example of the number of pizza slices and games Robert can buy if he spends all his money.d) Prove algebraically that you’re above example in C is true.
