Answer:
Manufacturers has to produce 63 DVD/Blu-Ray players to achieve a minimum cost of $644
Step-by-step explanation:
The cost equation is given as:

This is a quadratic equation in general form, which is:

Matching, we can say:
a = 0.04
b = -5
c = 800
The minimum occurs at 
and the minimum value would be to place that "x" value into the equation.
First, we find the minimum using values of a and b:

Plugging this into original, we get:

Rounding off to nearest whole number, we can say:
Manufacturers has to produce 63 DVD/Blu-Ray players to achieve a minimum cost of $644
Answer:
M<E=T M<T=E
Step-by-step explanation:
As you can see in the trapezoid the show you only one two sides that are equals so that's mean that the angles are congruent each other.

- [Frac] Divide/Simplify:

When we divide (x + 2), we would have a <em>removable</em> <em>discontinuity</em>. If we were to graph the original function, we would see at x = -2 there would be a hole in the graph.
Answer: 0.9660
Step-by-step explanation:
Given: Mean : 
Variance : 
⇒ Standard deviation : 
The formula to calculate z is given by :-

For x= -3

The P Value =
For x= 3
The P Value =

Hence, the probability that a given error will be between -3 and 3=0.9660
