Jennifer attempted to simplify the expression below. −5●(−1.75x−1.25)+3●(−2x−1)

Her work, step by step, is shown below.

Step 1: −5●{(−1.75x+(−1.25)}+3●{(−2x+(−1)}< br />
Step 2: 8.75x+6.25+(−6x)+(−3)

Step 3: 8.75x+(−6x)+6.25+(−3)

Step 4: 2.75x+2.75

In which step did she make her first error simplifying the expression?

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.)
