Answer:

The responses to the given can be defined as follows:

Step-by-step explanation:

For point a:

fixing probability vector that is W = [a b c]

\therefore

relation: WT =W

\to 0.5a+0.3b+0.2c=a ..................(1)\\\\  \to  0.4a+0.4b+0.3c=b..............(2)\\\\  \to  0.1a+0.3b+0.5c=c.................(3)

solving the value:

a=0.3387 \\\\ b=0.3710\\\\ c=0.2903

Therefore the stationary distribution \pi =[0.3387 \ 0.3710\  0.2903]

For point b:

\pi will be limiting distribution if \pi_j=\lin_{n\to \infity} (X_n=\frac{j}{X_0}=i) \Sigma_{\sqrt{j}} n_j=1

\pi satisfies the above condition so, it is limiting the distribution.

<u>Complete Question</u>

The table shows the number of grade 7 and grade 8 students on the student council at Jeremy’s school.

Number of Students

  • Grade 7 - 17
  • Grade 8 - 34

Answer:

C- The number of outcomes representing each grade level does not change after the first student is chosen.

Step-by-step explanation:

The ratio of Grade 7 students to Grade 8 students is:

17:34

This written in reduced form is 1:2

Therefore, initially, the six parts of the cube can be divided into the ratio 2:4 which Jeremy did.

However, after the first selection of a student, the ratio of Grade 7:Grade 8 student changes since the same student cannot be chosen more than once.

Therefore the cube rolls represent only the first student choice and may not be accurate for subsequent rolls.

The correct option is C.

The volume of a gas in a container varies inversely with the pressure on the gas. A container of helium has a volume of 370in3 u
Elan Coil [88]

Answer:

Step-by-step explanation:

When two variables vary inversely, it means that an increase in one would lead to a decrease in the other and vice versa. Since the volume of a gas, V in a container varies inversely with the pressure on the gas, P, if we introduce a constant of proportionality, k, the expression would be

V = k/P

If V = 370 in³ and P = 15psi, then

370 = k/15

k = 370 × 15 = 5550

The equation that relates the volume, V, to the pressure, P would be

V = 5550/P

if the pressure was increased to 25psi, the volume would be

V = 5550/25 = 222 in³

Lostsunrise [7]
We know that

<span>4 1/2 gallons-------> (4+2+1)/2-----> 9/2 gallons
</span>
1 <span> wall in the house will need --------> 3/4 of a gallon of paint
</span> X wall-----------------------------------> 9/2 gallons
x=(9/2)/(3/4)----> 9*4/2*3-----> 36/6----> 6 walls

the answer is
6 walls
