1. C.

The rule of powers is that when a parenthesis is raised to a power, you multiply the two numbers. Since it is being raised to the second power, it needs to have a 10 in the parenthesis. That would make 20.

2. B

Firstly 10^2 = 100, so we know that the number must be 10. That leaves us with just A and B. Then we know the same thing from the previous equation, that they need to be multiplied together.

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

Fynjy0 [20]

Answer:

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

Step-by-step explanation:

<u>Combined Average</u>

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
