Answer:

unit \: rate =  \frac{distance}{time}  \\

substitute:

unit \: rate =  \frac{( \frac{1}{3} ) }{( \frac{1}{9}) }  \\  \\  =  \frac{1}{3}  \div  \frac{1}{9}  \\  \\  =  \frac{1}{3}  \times 9 \\  \\  = { \underline{ \:  \: 3 \: miles \: per \: hour \:  \: }}

Algebra always makes things sound harder than they actually are, and weird vocabulary can mix up the steps we knew so well.


Part 1: Multiply the first equation by a 2 so that you can cancel out the y variable.

6x - 2y = 0

5x + 2y = 22


Part 2: Actually cancel out the y variables, and combine like terms.

11x = 22


Part 3: Solve for "x" by dividing both sides by 11

x = 2


Part 4: Substitute the variable "x" with the value we just solved for in the original equation.

3(2) - y = 0

6 - y = 0

Then, solve for y by adding y to both sides

6=y


Solution Set = {2,6}

You own a company that employs three salespeople, Quentin, Michael and Bubba. Quentin makes 30% of the sales, Michael 45%, and B
borishaifa [10]

Answer:

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.
