Of the $10$ kids in a chess club, $5$ are left-handed and $5$ are right-handed. the club holds a round-robin tournament in which
Nataliya [291]

The total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 is the fraction of all games at the tournament Anita plays.

<h3>How to carry out Permutation and Combination?</h3>

We are given that there are 5 girls and 5 boys in a chess club.

Thus, total games that girls play against a boy = 5×5 = 25

The number of games a girl play against another is the total number of games = 10

The number of games that are boy vs boy = 10

The number of games Boy vs Boy + Girl vs Girl + Boy vs Girl = 10 + 10 + 25 =  45

Fraction of the games that are boy vs boy = 10/45 = 2/9

If Anita is one of the club members, then Anita will have to play against 9 people at the tournament.

Total number of games = 45

Then the fraction of all games at the tournament Anita play the game.= 9/45 ⇒ 1/5

Thus, the total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 fraction of all games at the tournament Anita plays.

Based on the quantity of avocados consumed by both cities, the answer to this would be<u> 60% more. </u>

Phoenix consumes 120 million avocados and Denver consumes 75 million.

<h3>Phoenix Percentage consumption over Denver</h3>

First find the difference between the avocados consumed:

= 120 - 75

= 45 million

In percentage this is:

= Quantity difference / Denver consumption x 100%

= 45 / 75 x 100%

= 60%

In conclusion, Phoenix consumes 60% more.

Why are generic pharmaceuticals significantly cheaper than name brand ones? <br><br> NEED HELP ASAP
RSB [31]

Answer:

Generic drugs tend to cost less than their brand-name counterparts because generic drug applicants do not have to repeat animal and clinical (human) studies that were required of the brand-name medicines to demonstrate safety and effectiveness.

Generic pharmaceuticals are significantly cheaper than name brand ones because generic pharmaceuticals are not protected by patent law, so the lack of barriers to entry and increased competition keep prices down.

Also, the makers of generic drugs do not have to cover the cost of developing and marketing a new product.
