Answer:
The selling price that will maximize profit is $56.
Step-by-step explanation:
Given : It costs 12 dollars to manufacture and distribute a backpack. If the backpacks sell at x dollars each, the number sold, n, is given by
To find : The selling price that will maximize profit ?
Solution :
The cost price is $12.
The selling price is $x
Profit = SP-CP
Profit = x-12
The profit of n number is given by,
Substitute the value of n,
Derivate w.r.t x,
Put it to zero for critical point,
Derivate again w.r.t x, to determine maxima and minima,
It is a maximum point.
Therefore, the selling price that will maximize profit is $56.

Answer:
During halftime of a basketball game, a sling shot launches T-shirts at the crowd. A T-shirt is launched with an initial upward velocity of 78 feet per second. The hight of the t-shirt (h) in feet after t seconds is given by the function h=-16t^2+78t+5. How long will it take the T-shirt to reach its maximum height? What is the maximum height? What is its maximum height?

Using a calculator, it is found that the correlation coefficient is of 0.997.
<h3>What is a correlation coefficient?</h3>
It is an index that measures correlation between two variables, assuming values between -1 and 1.
If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
In this problem, we have the data-set for the weight and for the height. To find the coefficient, we insert each data-set in the calculator. Doing this, we find that the coefficient is of 0.997.
