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:
D. 28.54
Step-by-step explanation:
To find the area of the shaded region, find the area of the circle and divide it in 4. This will the area of the portion with the triangle.
Now, find the area of the triangle and subtract the two. The resulting value will be the area of the shaded region.
Circle:

Divide by 4 for the area of the section with the triangle.
314/4 = 78.5
Triangle:

Subtract the two, 78.5 - 50 = 28.5.

Step-by-step explanation:
(2, 5) and (3, 8)
m=(y2-y1)/(x2-x1)
m=(8-5)/(3-2)
m=3/1
m=3
