Answer:
Step-by-step explanation:
So we have the equation:
And we want to solve for R.
First, let's multiply both sides by J to remove the fraction on the right. So:
Simplify the right:
We can rewrite our equation as:
So, to isolate the R variable, divide both sides by I²t:
The right side cancels, so:
And we are done!
The "mean" of a group of numbers is also called their "average".
To calculate the mean, add up all the numbers, then
divide the sum by the number of items on the list.
Step #1: Addum up: 3+7+2+9+4+7+3+7+5+2 = 49
Step #2: Count the number of items on the list: I count 10 .
Step #3: Divide the sum by the number of items on the list.
49 / 10 = 4.9
The mean (average) of the numbers on that list is 4.9 .
