Given the expression 12 over 12 to the third power.

4vir4ik [10]

Part 1:
Before we begin, you need to remember the following rule:
$\frac{x^a}{x^b} = x^{a-b}$

The given expression is:
$\frac{12}{12^3}$

Since the base is the same in both numerator and denominator, we can apply the above rule. This means that:
$\frac{12}{12^3}$ = 12¹⁻³ = 12⁻²

Part 2:
Before we begin, you need to remember the following rule:
x⁻ᵃ = $\frac{1}{x^a}$

Now, from part 1, we simplified the expression into 12⁻²
Since the power is negative, we can apply the above rule.
This means that:
12⁻² = $\frac{1}{(12)^2} = \frac{1}{12*12} = \frac{1}{144}$

Hope this helps :)

Hey there!

The mean of the numbers is the average. To find the mean we will simply add all the numbers together, and divide them by the amount of numbers there are. Easy, peesy, lemon squeezy. Lets get started.

7 + 10 + 22 + 10 + 12 + 10 + 12 = 83

Now that we have added those altogether, we can divide them by the amount of numbers there are. The amount of numbers there are comes to a total of 7. Therefore...

83 divided by 7 = 11.857

Answer Choice B. 11.9 is your correct answer.
