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:

                       y = -10x^2 + 689x -6775

We are to determine the profit maximizing selling price ( x )

From the properties of a parabola equation of the form:

                      y = ax^2 + bx + c

The vertex ( turning point ) or maximum/minimum point is given as:

                     x = -\frac{b}{2a} \\\\x = - \frac{689}{2*(-10)} =  \frac{689}{20}\\\\x = 34.45

The profit maximizing selling price of widgets would be x = $34.45.

Ron has a bag containing 3 green pears and 4 red pears he randomly selects a lead then randomly selects another pear without rep
Alborosie
First pear            Second pear      probability

green (3/7)---------green (2/6)         (3/7)*(2/6) = 1/7
                  ---------red (4/6)             (3/7) *(4/6) = 2/7

red (4/7)-------------green (3/6)        (4/7)*(3/6) = 2/7
             -------------red (3/6)             (4/7)*(3/6) = 2/7
                                                     -------------------------
                                                     1/7 + 2/7 + 2/7 + 2/7 = 1

The probailities that two are green are: 1/7

The probabilities that one is green and the other is red are:2 /7 + 2/7 = 4/7

The probabilities that two are red are: 2/7
