Rubber duckies. A game at a carnival has 75 rubber ducks floating in water. The ducks are numbered 1 to 75, with the numbers written on their under- sides so they can’t be seen. To play, you select a duck and see what number it has. If the number is less than 60, you win a consolation prize. If the number is at least 60 but less than or equal to 70, you win a stuffed duck. If the numb er is greater than 70 you win a giant, stuffed banana. What is the probabili ty you win a stuffed duck? What is the probability you don’t win a duck or a banana?

- Can you please answer all the following grade 12 advanced functions questions. I will make sure to leave a thumbs up on the answer if it is written by hand on paper without ai. Thanks a lot!arrow_forward18. Consider the functions f(x) = and g(x) = 3*. x-3 a) Write a simplified equation that represents f-1 (g(x)).* b) State the domain and range of f-1 (g(x)).arrow_forward20. After a school dance, Carlos is thinking of asking Keiko out on a date. The probability that Carlos will ask can be modeled by the function f(x)=0.45 sin x + 0.5, and the probability that Keiko will say yes can be modeled by the function g(x) = -0.08x(x-7), where x represents the number of days following the school dance. The conditional probability that Carlos asks Keiko and Keiko says yes can be modeled by the combined function y = f(x)g(x). This combined function is shown on the graph. y 15 Answers to the following questions are approximate. Answers may vary but all reasonable answers will be accepted. a) Use the graph to approximate: How many days after the dance should Carlos ask Keiko to go out with him? x b) Use the graph to approximate: If Carlos asks Keiko on the day that you recommended above, approximately what is the probability that they will go on the date? c) According to the graph, at what point does Carlos have absolutely no chance of dating Keiko?arrow_forward

The total weekly salary of each employee can be represented by the functions shown, where S represents weekly salary, in dollars, and x represents the number of items sold. Assuming that they sell the same number of items in a week, what is the minimum number of items they have to sell so that Jill's weekly salary is at least $100 more than Jack's? JACK: S = 100 + 5x JILL: S=80+6x 23. You are given the following two functions: f(x)=2x-3 9(x) = −2 (¹)²**5 + 18 2x+5 Your teacher claims that the zero of the function g(f(x)) is greater than the zero of g(x).
