Answer:
781250
Step-by-step explanation:
Let x = length of fenced side parallel to the side that borders the river
and y = length of each of the other two fenced sides
Then, x + 2y = 2500
<=> x = 2500- 2y
Area = xy = y(2500-2y)
= -
+ 2500y
The graph of the area function is a parabola opening downward.
The maximum area occurs when y = -2500/[2(-2)] = 625
x = 2500-2y = 1250
The maximum area that can be enclosed = xy = 1250*625 = 781250

Step-by-step explanation:
Answer: 9% parameter, 3% statistic
Step-by-step explanation: Parameter and statistic are are statistical terms used to describe a group or observation.
However, the distinction between a parameter and a statistic is in the measured observation.
Parameter is used to describe an entire population while statistic is used to describe a sample.
Where a population refers to the entire number of people or inhabitant of a particular country while a sample refers to a subset of observation drawn randomly from a population which serves a representative of the entire population.
In the question above, 9% is used to make a description of the whole American population who are at least 75 years of age. While,
3% is used to describe a subset of the American population (sample) who are 75 years or older.
