Answer:
The maximum amount spent on clothing and footwear occured in late 2008.
Step-by-step explanation:
The existence of a maximum in a continuous differentiable function is determined by the First and Second Derivative Test, which consist on the following process:
1) First and second derivatives of the given function are obtained.
2) First derivative is equalized to zero and roots are found. (Critical points)
3) Each critical point is evaluated in the second derivative expression in order to determine if each point is an absolute maximum (f'' < 0) or minimum (f'' > 0).
The first and second derivatives of the function are, respectively:
Since first derivative is a first-order polynomial (linear function), there is a root, which is found herein:
The second derivative indicates that critical value leads to an absolute maximum, therefore, the maximum amount spent on clothing and footwear occured in late 2008.
Answer: The total registered voters of the city Raleigh i.e. 9500 registered voters.
Step-by-step explanation:
In statistics , the term population refers to the entire group of individuals having similar characteristics .
