1/2 < __ < 4/5

1/2 = 0.5
4/5 = 0.8

they got 2/3 because 2/3 = 0.66 and it falls in between 1/2 and 4/5.

The other answer choices obviously did not fall in the solution range

2/3 works here because its value is greater than 1/2 but less than 4/5. An easy way to visualize this is to take the decimal value of each number as decimals are often easier to understand than fractions.

1/2=.50
2/3=.67
4/5=.80

This inequality could be rewritten as .50 < .67 < .80 and would have the same value.

Let angle be alpha

$\\ \rm\Rrightarrow Area=50.24$

$\\ \rm\Rrightarrow \dfrac{\alpha}{360}\pi r^2=50.24$

$\\ \rm\Rrightarrow \alpha 3.14r^2=18086.4$

$\\ \rm\Rrightarrow \alpha r^2=5760$

$\\ \rm\Rrightarrow r^2=\dfrac{5760}{\alpha}$

$\\ \rm\Rrightarrow r=\sqrt{\dfrac{5760}{\alpha}}$

If you have angle measure in degree put in place of Alpha and get the value elaw this is our final answer

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%
