Answer:

x/2 + 21 = 36

First we get rid of constants to isolate the variable.

In order to do that we must do the inverse operation.

Inverse operation of addition is subtraction.

-21           -21(subtracting 21 from both sides, whatever we do to the left side we do it to the right side too)

x/2 = 15

inverse property of division is multiplication

x2    x2

X = 30

Answer:

X=28

Step-by-step explanation:

X/2 + 21 = 36

X/2 = 36-21

X/2=14

X=14*2

X=28

Sedaia [141]

Answer:

Step-by-step explanation:

Given data:

SS={0,1,2,3,4}

Let probability of moving to the right be = P

Then probability of moving to the left is =1-P

The transition probability matrix is:

\left[\begin{array}{ccccc}1&P&0&0&0\\1-P&1&P&0&0\\0&1-P&1&P&0\\0&0&1-P&1&P\\0&0&0&1-P&1\end{array}\right]

Calculating the limiting probabilities:

π0=π0+Pπ1                 eq(1)

π1=(1-P)π0+π1+Pπ2     eq(2)

π2=(1-P)π1+π2+Pπ3    eq(3)

π3=(1-P)π2+π3+Pπ4    eq(4)

π4=(1-P)π3+π4             eq(5)

π0+π1+π2+π3+π4=1

π0-π0-Pπ1=0

→π1 = 0

substituting value of π1  in eq(2)

(1-P)π0+Pπ2=0

from

π2=(1-P)π1+π2+Pπ3  

we get

(1-P)π1+Pπ3 = 0

from

π3=(1-P)π2+π3+Pπ4

we get

(1-P)π2+Pπ4 =0

from π4=(1-P)π3+π4  

→π3=0

substituting values of π1 and π3 in eq(3)

→π2=0

Now

π0+π1+π2+π3+π4=0

π0+π4=1

π0=0.5

π4=0.5

So limiting probabilities are {0.5,0,0,0,0.5}

Q1.

D= 1546

T= 67

S= D/T=S

1546/ 67= 23.07

Q2.

D= 29

T= 32

S= D/T=S

29/32= 0.91

Q3.

D= 43

T= 40

S= D/T=S

43/40= 1.08

Q4.

D= 2467

T= 4.41

S= D/T=S

2467/4.41= 559.41
