What is the answer to this question and the solution to it

To find the average of many values, add all the values and divide by the number of values.

The values are: 15, 8, 12, 12, 6, 18, 10, 15

There are 8 values.

Add the values: 15 + 8 + 12 + 12 + 6 + 18 + 10 + 15 = 96

Now divide the sum by the number of values:

average = sum/number of values

average = 96/8

average = 12

A   12

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
