<h2>Answer with explanation:</h2>

He has 20 rock songs, 15 country songs, 10 world songs and 5 classical songs.

There are 50 in total.

The fraction of songs which are rock songs are:

$\dfrac{20}{50}$

which in simplest fraction is given by:

$\dfrac{2}{5}$

and on multiplying the fraction with 100 we get the percent of songs.

Hence,

$\dfrac{2}{5}\times 100=40\%$

The fraction of songs which are country songs are:

$\dfrac{15}{50}$

which in simplest fraction is given by:

$\dfrac{3}{10}$

Hence,

$\dfrac{3}{10}\times 100=30\%$

The fraction of songs which are world songs are:

$\dfrac{10}{50}$

which in simplest fraction is given by:

$\dfrac{1}{5}$

Hence,

$\dfrac{1}{5}\times 100=20\%$

The fraction of songs which are classical songs are:

$\dfrac{5}{50}$

which in simplest fraction is given by:

$\dfrac{1}{10}$

Hence,

$\dfrac{1}{10}\times 100=10\%$

6. What is the minimum vertical distance between the parabolas <img src="https://tex.z-dn.net/?f=%20y%3Dx%5E%7B2%7D%2B1%20%5Ctex

Arada [10]

Answer:

0.75.

Step-by-step explanation:

1) the required vertical distance is the distance between two vertexes.

2) according to the item 1, the coordinates of the vertexes are:

(y=x²+1): x₀=0; y₀=1;

(y=x-x²): x₀=0.5; y₀=0.25;

3) according to the item 2, the distance between 1 and 0.25 is 0.75.
