In q1-q2 try the following operations in matlab and explain your answers (one sentence of explanation per each operation will be sufficient) q1. floating point number systems are only finite approximations to the real number system usually based on a binary representation of numbers. thus powers of 2 may be represented exactly, but powers of 10, for example 0.1, may not have a finite binary representation so must be approximated by the closest floating point number a logical true is frequently represented by 1 (or any non-zero number in some systems) and a logical false by 0. (a) 0.75*0.2-0.15 floorx) is the largest integer x (b) floor(6/1), floor(0.6/0.1) h le-14, 100+h-100 (c) (d) h le-15, 100+h-100 (e) eps, realmax, realmin (f) eps, 1+eps > 1, +eps/2> 1

Write two subtraction equations that are equivalent to 5 + 12 = 17.

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.)
