Explanation:

Answer 2

The linear regression equation of the given set of points is required.

The required regression equation is [tex]y=1.98x+0.436[/tex]

The points are

x y       xy                x^2      y^2

1 1.24      1.24           1   1.5376

2 5.23     10.46        4   27.3529

3 7.24     21.72         9   52.4176

4 7.6     30.4             16   57.76

5 9.97     49.85        25   99.4009

6 14.31     85.86        36   204.7761

7 13.99    97.93        49   195.7201

8 14.88    119.04        64   221.4144

9 18.04    162.36       81   325.4416

10 20.7      207          100   428.49

55 113.2   785.86      385   1614.3112 Total

The image of the table is attached.

[tex]\sum y=55[/tex]

[tex]\sum y=113.2[/tex]

[tex]\sum xy=785.86[/tex]

[tex]\sum x^2=385[/tex]

[tex]\sum y^2=1614.3112[/tex]

[tex](\sum x)^2=55\times 55=3025[/tex]

n = Number of observations = 10

The equation of a line is given by

[tex]y=bx+a[/tex]

[tex]a=\dfrac{\left( \sum y \right)\left( \sum {{x}^{2}} \right)-\left( \sum x \right)\left( \sum xy \right)}{n\left( \sum {{x}^{2}} \right)-{{\left( \sum x \right)}^{2}}}\\\Rightarrow a=\dfrac{113.2\times385-55\times785.86}{10\times385-3025}\\\Rightarrow a=0.436[/tex]

[tex]b=\dfrac{n\left( \sum xy \right)-\left( \sum x \right)\left( \sum y \right)}{n\left( \sum {{x}^{2}} \right)-{{\left( \sum x \right)}^{2}}}\\\Rightarrow b=\dfrac{10\times785.86-55\times113.2}{10\times385-3025}\\\Rightarrow b=1.98[/tex]

The required regression equation is [tex]y=1.98x+0.436[/tex]

Explanation:

The word "anime" in English refers to an animation style popular in Japan. The word comes from the Japanese name for animation. Anime is heavily influenced by Japanese comics, manga, and features characters with enlarged eyes, big hair, long limbs, exaggerated expressions, limited motion, and brush-stroke outlines. Anime has a large audience both in and outside of Japan.

Anime is also considered a visual art form as it displays a wide range of drawing styles. Typically, anime and manga feature characters with large eyes so they can display emotions. Osamu Tezuka, who is believed to have been the first one to use this feature, was inspired by American characters such as Betty Poop, Bambi, and Mickey Mouse.

Not only has anime drawn special interest toward the culture of Japan, it has also made significant impacts on the Western culture. Many Westerners have expressed an interest in the Japanese language to better understand the Japanese culture, art, and technology of anime.
