Question

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.)

Answer 1

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:

`mean\text{ = }\frac{sum\text{ }of\text{ }all\text{ }games}{#games}`

`206=\frac{sum\text{ }of\text{ }all\text{ }games}{24}`

sum of all games = 206 * 24 = 4944

new bowling score:

games = 25

final score = 257

`mean\text{ =}(4944+257)/(25)=208.04`

The answer is:

208.0
