A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the
1 answer:
Answer:
x = $34.45
Step-by-step explanation:
Solution:-
The company makes a profit of $y by selling widgets at a price of $x. The profit model is represented by a parabola ( quadratic ) equation as follows:
We are to determine the profit maximizing selling price ( x )
From the properties of a parabola equation of the form:
The vertex ( turning point ) or maximum/minimum point is given as:
The profit maximizing selling price of widgets would be x = $34.45.

Follows are the solution to the given points:
Step-by-step explanation:
In point A:
In point B:
In point C:
For df = 70, the top 5% critical t score
tcrit = 1.666914479
Thus,
In point D:
For df = 70, the top 5% critical t score
tcrit = -1.666914479
In point E:
The lower cutoff is 0.10 in the center, which would be around 80 %. The critical point therefore is
tcrit = -1.293762898
In point F:
The lower cutoff is 0.90 in the center, which would be around 80 %. The critical point therefore is
tcrit = 1.293762898
Answer:
40,000 units on the first day then 18% per week
Step-by-step explanation:
Exponential function:
An exponential function has the following format:
In which r is the rate of change, as a decimal.
In this question:
The number of phones sold in thousands of units per day, in t weeks since the date of release, is:
Since , it solds 40,000 on the first week.
The rate of percentage increase is:
1 + r = 1.18
r = 0.18
So an increase of 0.18 = 18% a week.
So the correct option is:
40,000 units on the first day then 18% per week
