We will have the following:
Using exponential regression we will have that the line of best fit will be:

Now, we will have that:

So, the approximation using linear regression gives us as solution approximately 29.7 years; thus the closest one to match is then
Irrational Number
You can tell this easily because the square root of 50 isn't a perfect number.

I picked a point and counted up 3 and over 2 to the next point
Answer: −10
Step-by-step explanation: 9^2−21/−6
81−21/−6
60/−6
−10
To find decimal, divide 13/50= 0.26
To find percent divide decimal above by 100 (or move decimal place to the right two places).
0.26/100= 26%
Hope this helps! :)
