Bill's mean (average) bowling score is 206. This mean is based on bowling 24games. Bill bowls another game and gets a score of 257. What will be his newmean (average) bowling score? (Round your answer to the nearest tenth, ifnecessary.)

Respuesta :

In this case, we'll have to carry out several steps to find the solution.

Step 01:

data:

bowling score = 206

games = 24

Step 01:

mean:

original bowling score:

[tex]mean\text{ = }\frac{sum\text{ }of\text{ }all\text{ }games}{#games}[/tex]

[tex]206=\frac{sum\text{ }of\text{ }all\text{ }games}{24}[/tex]

sum of all games = 206 * 24 = 4944

new bowling score:

games = 25

final score = 257

[tex]mean\text{ =}\frac{4944+257}{25}=208.04[/tex]

The answer is:

208.0
