You notice that 10 degrees c equals 50 degrees fahrenheit 20 degrees c equals 68 degrees fahrenheit and 30 degrees celsius equals 86 degrees fahrenheit. use the inductive reasoning to predict the value in degrees fahrenheit is 40° c

Which property was used to simplify the expression? 3c+9 +4c=3c+4c+9

Math question.. plz me .. best answer all

Afriend of mine is giving a dinner party. his current wine supply includes 10 bottles of zinfandel, 8 of merlot, and 11 of cabernet (he only drinks red wine), all from different wineries. (a) if he wants to serve 3 bottles of zinfandel and serving order is important, how many ways are there to do this? ways (b) if 6 bottles of wine are to be randomly selected from the 29 for serving, how many ways are there to do this? ways (c) if 6 bottles are randomly selected, how many ways are there to obtain two bottles of each variety? ways (d) if 6 bottles are randomly selected, what is the probability that this results in two bottles of each variety being chosen? (round your answer to three decimal places.) (e) if 6 bottles are randomly selected, what is the probability that all of them are the same variety? (round your answer to three decimal places.)
