Given:





To find:
The variance. of combined set.
Solution:
Formula for variance is
...(i)
Using (i), we get




Similarly,




Now, after combining both sets, we get




Therefore, the variance of combined set is 15.4.
Hello!
The Associative Property of Multiplication states the following:
a × (b × c) = (a × b) × c
The equation given in the image above follows the same form:
9 × (5 × 2) = (9 × 5) × 2
Therefore, the given equation must be representative of the Associative Property.
I hope this helps!

Answer:
There are 729 possible results are there for the series
Step-by-step explanation:
If we have n trials, each with m possible outcomes, the total number of possible outcomes is:

In this question:
6 games(trials), so
.
Each with three possible outcomes, so 
Then:

There are 729 possible results are there for the series
