What’s the combined average of Altuve’s weighted average below:

Fynjy0 [20]

Answer:

The combined average of Altuve's weighted averages is 1 for 2 or 1/2

Step-by-step explanation:

Combined Average

On Friday, Altuve had 3 out of 5 successes

On Saturday, Altuve had 2 out of 4 successes

On Friday, Altuve had 1 out of 3 successes

The total successes are 3+2+1=6

The total tries are 5+4+3=12

The combined average is:

$\displaystyle \bar x=\frac{6}{12}$

Simplifying:

$\displaystyle \bar x=\frac{1}{2}$

The combined average of Altuve's weighted averages is 1 for 2 or 1/2
