Mike can bind 109 flowers per hour, John can bind 116 flowers

antiseptic1488 [7]

Hello!

We know that mike can bind 109 flowers per hour.

Lets create an equation to remember this.

Mikes equation:

109x = y

We know that John can bind 116 flowers per hour, here is his equation.

Johns equation:

116x = y

Question: If they work together for 5 hours, how many flowers can they bind?

First, plug in the number five in both equations.

Second, solve the equation by multiplying.

Mikes:

109(5) = y

109 times 5 is 545

y = 545

Johns:

116(5) = y

116 times 5 is 580

y = 580

We want to know how many flowers can they bind if they work together.

This means we need to add the answers of the equations from both mike's and john's together.

545 + 580 = 1,125

The answer is 1,125

Problem 7.1 (10 points) Let pXnqn"0,1,... be a Markov chain with state space S " t1, 2, 3u and transition probability matrix P "

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.

One night, it is 24LaTeX: ^\circ

tatuchka [14]

Answer:

$T^\circ = -12^\circ$

Step-by-step explanation:

Given

Represent the temperature in Tucson with T and that in Minneapolis with M.

From the first statement, we have:

$T^\circ = M^\circ - 24^\circ$

From the second, we have:

$T^\circ = -M^\circ$ or $M^\circ = -T^\circ$ --- i.e. both are opposite numbers

Required

Find T

To calculate T, substitute -T for M in $T^\circ = M^\circ - 24^\circ$

This gives:

$T^\circ = -T^\circ - 24^\circ$

Collect Like Terms

$T^\circ +T^\circ =- 24^\circ$

$2T^\circ =- 24^\circ$

Make T the subject

$T^\circ =- 24^\circ/2$

$T^\circ = -12^\circ$

Hence, the temperature in Tucson is $-12^\circ$
