The water level in a draining reservoir is changing such that the depth of water decreases by 7.5% per hour. If the water starts at a
depth of 45 feet, then which of the following functions properly
models the depth, d, as a function of time, t, in hours since it started
draining?
(1) d = 45(.075)'
(2) d = 45(.925)'
(3) d = 45(7.5)'
(4) d = 45(92.5)'

please answer fast, it’s for a timed test!!!

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.)
