Answer:

\frac{1}{a} =\frac{1}{b} +\frac{1}{c}  \\ \\\frac{1}{a} =  \frac{1}{3} + \frac{1}{2/3} \\\\\frac{1}{a} =  \frac{1}{3} + \frac{3}{2}\\\\\frac{1}{a} =  \frac{11}{6}\\\\a = \frac{6}{11}

Answer:

  y = 7

Step-by-step explanation:

The slope is ...

  m = (7 -7)/(0 -4) = 0

The y-intercept is the point (0, 7), so the slope-intercept equation is ...

  y = mx +b

  y = 0·x +7

Simplifying this puts it in standard form:

  y = 7

A business that offers services to people by providing many amusement and fun with gate fees

The algebraic equations to be used is the general linear equation

Y = MX + C

Where

Y = total income or money realised

M = rate or price rate

X = number of goods or services

C = flat rate or gate fees

The business can also operate differently by using exponential equation

A = P(1 + R%)^t

Where

A = profit

P = capital

R = rate

t = time

Sedaia [141]

Answer:

A) distribution of x2 = ( 0.4167 0.25 0.3333 )

B) steady state distribution = \pi a \frac{4}{9}   ,    \pi b  \frac{2}{9}     ,   \pi c \frac{3}{9}

Step-by-step explanation:

Hello attached is the detailed solution for problems A and B

A) distribution states for A ,B, C:

Po = ( 1/3, 1/3, 1/3 )  we have to find the distribution of x2 as attached below

after solving the distribution

x 2 = ( 0.4167, 0.25, 0.3333 )

B ) finding the steady state distribution solving

\pi  p = \pi

below is the detailed solution and answers
