Option C:
is the predicted population when 
Explanation:
The regression equation for an exponential data is 
Where x is the number of years and
y is the population
We need to determine the predicted population when 
The population x can be determined by substituting
in the equation 
Thus, we have,



Using the logarithmic definition
then 


Rounding off to the nearest whole number, we get,

Thus, the predicted population when
is 316
Hence, Option C is the correct answer.
Answer:
15.78 %
Step-by-step explanation:
It is given that,
Miguel made 80 on his Math test. He made 95 in last week's Math test.
We need to find the percent change on his scores. It can be calculated as follows :

So, there is a percent change of 15.78%.
Answer:
The correct answer is: Negative correlation.
Step-by-step explanation:
The negative correlation determines the relationship between two variables, it says that there is an inverse relationship between two variables, whenever one of them is decreasing, the other one increases, and it's the same in reverse.
