Find the equilibrium point for the pair of demand and supply functions. Here q represents the
olya-2409 [2.1K]

The equilibrium point for the pair of demand and supply function is 100

We have been two linear function, one is linear supply function and other is linear demand function.

In general , linear supply function is given as:

                            Qs = x + yP

                       Where , Qs = quantity supplied

                                        x = quantity

                                        P = price

And linear demand function is given is :

                             Qd = x + yP

                      Where , Qs = quantity supplied

                                        x = quantity

                                        P = price

According to the question,

                   Linear supply function is q = 300 + 5x

          And  linear demand function is q = 4800 – 40x

To find the equilibrium point we will put two quantities equal, that is,

                                 Qs = Qd

                      300 + 5x = 4800 – 40x

                        5x + 40x = 4800 – 300

                          45x = 4500

                             x =  100

Hence the equilibrium point is 100

Brooke had 70 chairs but he had less than20 rows how many chair he can put on each row
RideAnS [48]
Put in a equality

20 > (70/x)

then you solve 

20x > 70

x>70/20

x> 3.5    you can not put part of a chair in a row so you round up

****You can put  4 or more chairs in a row****

What is the slope of a line perpendicular to the line whose equation is
GenaCL600 [577]

Answer:

The slope or incline is -5

Step-by-step explanation:

rewrite to get the form

y = ...

x - 5y = -10

- 5y = -10 -x

divide left and right if the = sign by -5 gives:

(-5/-5)y = (-1/-5)x + (-10/-5)

y = 1/5x +2

So the incline is 1/5

a perpendicular line has an incline of -1 *5/1 = -5

The slope or incline is -5

3. A medical devices company wants to know the number of MRI machines needed per day. A previous study found a standard deviatio
lozanna [386]

Answer:

173 MRI machines

Step-by-step explanation:

Margin of error E = 0.5

Confidence interval 90% = 1-0.9 = 0.1

Standard deviation = 4 hours

Number of MRI machines needed per day n, = [(z alpha/2 * SD)/E]²

Z alpha/2 = 1.645 at alpha = 0.1

Inputting these values into n we have that

[(1.645*4)/0.5]²

= 13.16²

= 173.18 is approximately equal to 173

The company has to study 173 machines.
