Area of a square = L * L
As you know 17 * 17 = 289
So length of one side of square equals 17
A= P(1 + r/n) ^nt
21000=7000(1+0.055/2)^1t
t = 20.52 years
The pattern is x3 so it's 108
There will be 2 bacterias after 20 minutes
Steps to finding the M.A.D
1. Find the mean of the data!
- all all the numbers up and divide by how many numbers there are
2. Find the absolute value of the difference between each data value and the mean:
|data value – mean|.
3. Find the sum of the absolute values of the differences
4. Divide the sum of the absolute values of the differences by the number of data values.
I hope I helped! Tell me if this is confusing or not :)
