Answer:

r=-3

Step-by-step explanation:

We have the equation:

\displaystyle \frac{1}{3}r+1=-\frac{2}{3}r-2

And we would like to solve for <em>r</em>.

First, we can multiply both sides by the denominator 3. This will remove the fractions. So:

\displaystyle 3(\frac{1}{3}r+1)=3(-\frac{2}{3}r-2)

Distribute:

\displaystyle r+3=-2r-6

Now, we can add 2<em>r</em> to both sides:

3r+3=-6

And we can also subtract 3 from both sides:

3r=-9

Finally, we can divide both sides by 3 to get:

r=-3

Your personal library contains books written by 165 authors. 60% of the authors are men. 40% of the authors write only nonfictio
Scorpion4ik [409]

Answer:

The probability that a book picked at random is either a work written by an author who writes only nonfiction or a work written by a man is 75.8%.

Step-by-step explanation:

The probability, in this case, has to be calculated using the sum rule because the events are independent. 

P = P(men) + P(non-fiction) - P(men non-fiction); where P is the probability. It means the probability that the random book was written by a man plus the probability that the random book was non-fiction minus the probability that the random book was written by a man who writes non-fiction. The probability that the random book was written by a man who writes non-fiction has to be subtracted, if not you will be duplicating it. 

Facts:

P(men) = 60% = 99/165

P(non-fiction) = 40% = 66/165

P(men non-fiction) = 40/165

P = P(men) + P(non-fiction) – P(men non-fiction)

P = 99/165 + 66/165 – 40/165

P = 125/165

P = 0.758 or 75.8%
