You own a company that employs three salespeople, quentin, michael and bubba. quentin makes 30% of the sales, michael 45%, and bubba 25%. while they are all competent, they do not enjoy completing the paperwork on their sales as required by the sec. of the sales quentin makes, he completes paperwork 90% of the time. when michael makes a sale, he completes the paperwork 80% of the time. when bubba makes a sale, he completes paperwork 85% of the time. you were recently fined by the sec for this reason, and have instituted tough new policies on this manner. however, you recently selected a file at random and found that the paper work was not in order. who is the most likely culprit?

Michael

Step-by-step explanation:

Look at the table below:

The probability of selecting a sale that was made by Quentin is .30, by Michael is .45 and by Bubba is .25.

Since Quentin completes paperwork 90% of the time, he doesn't complete paperwork 10% of the time, following this reasoning we can say that Michael doesn't complete paperwork 20% of the time and Bubba doesn't complete paperwork 15% of the time.

The probability of selecting a file and that it belongs to Quentin AND is incomplete is:

(Probability of selecting a Quentin's file) x (Probability is a Quentin incomplete file) = (0.30)(0.10) = 0.03

Using this same method we have that the probability that it belongs to Michael and is incomplete is (.45)(.20) = 0.09

That it belongs to Bubba and it's incomplete is (0.25)(0.15) = 0.037

The highest of these probabilities is the one that corresponds to Michael: 0.09, therefore he is the most likely culprit.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
