<h3>
Exact Area = 1200 - 300pi square cm</h3><h3>
Approximate Area = 257.522203923062 square cm</h3>
Work Shown:
The area of the rectangle is 40*30 = 1200 square cm
Note how we have 4 circles along the horizontal dimension which is 40 cm, so each diameter is 40/4 = 10 cm, and the radius is 10/2 = 5 cm
Each circle has an area of pi*r^2 = pi*5^2 = 25pi
There are 4*3 = 12 circles, so the circle areas combine to 12*25pi = 300pi
Using a calculator, we find that 1200 - 300pi = 257.522203923062 approximately. Round this however you need to.

Point estimate is the method of looking for an approximate value of some parameter - example: the mean (average) and it could be also the sample standard deviation of a population from random samples of the population.
To get the point estimate: 20 (people wearing hearing aids) / 304 (total random sample) = 0.0657894 or 0.066

Answer:
I) Option 2)
II) Minimum 35 passengers must be carried in the flight to make a profit.
Step-by-step explanation:
We are given the following in the question:
I) Number of seats in plane = 295
Estimated cost = $3,845
Cost per passenger= $110 per hour of flight
Let x be the number of passenger travelling by flight.
Total cost =
Then, we can design the profit function as:
The domain is the collection \of all the values of x for which the function is defined.
Thus, the domain of the profit function will be
Option 2)
II) least number of passengers it must carry to make a profit
Thus, minimum 35 passengers must be carried in the flight to make a profit.
