You need to explain what you posted.
It is the results of an exponential regression of a given data set.
The results show that the modelling function is
The regression coefficient is 0.97, which means that the model is quite close to the points on the data set.
HOWEVER, unfortunately the question did not state what x stands for, i.e. x is not properly defined.
Now back to the question:
What was the approximate number of mobile cellular subscriptions per 100 people in Zimbabwe in 2003.
A reasonable GUESS for the value of "x" in the regression equation is number of years since 2000.
So for 2003, x=3, and substitute in the formula to get a value.
Round this value to the nearest integer will give you the \(probably\) answer.
but how do i put that all together?
Substitute x=3 in the following:
AND remember that x has not been defined by the question, so x=3 is only a GUESS under circumstances of insufficient information, unless you have unposted additional information.
