Answer:
Step-by-step explanation:
Given that:

If we are to consider the estimator 
a. Then, for
to be an unbiased estimator ; Then:



b) If
are independent


Thus; in order to minimize the variance of
; then constant a can be determined as :

Using differentiation:

⇒

This implies that

So,
is minimum when 
As such;
if 
The base of the prism is a 6 cm square. Any cross section parallel to the base has the same dimensions as the base, so is a 6 cm square. Its area is ...

Answer:
exponential
Step-by-step explanation:
An exponential function is defined as a function with a positive constant other than 1 raised to a variable exponent. A function is evaluated by solving at a specific input value. An exponential model can be found when the growth rate and initial value are known.
The answer is B. 6.3 * 10^6
6.3 * 10^6 = 6,300,000
