A fair coin is tossed repeatedly with results Y0, Y1, Y2, . . . that are 0 or 1 with probability 1/2 each. For n ≥ 1 let Xn = Yn

Gekata [30.6K]

Answer:

False. See te explanation an counter example below.

Step-by-step explanation:

For this case we need to find:

$P(X_{n+1} = | X_n =i, X_{n-1}=i') =P(X_{n+1}=j |X_n =i)$ for all $i,i',j$ and for $X_n$ in the Markov Chain assumed. If we proof this then we have a Markov Chain

For example if we assume that $j=2, i=1, i'=0$ then we have this:

$P(X_{n+1} = | X_n =i, X_{n-1}=i') =\frac{1}{2}$

Because we can only have $j=2, i=1, i'=0$ if we have this:

$Y_{n+1}=1 , Y_n= 1, Y_{n-1}=0, Y_{n-2}=0$ , from definition given $X_n = Y_n + Y_{n-1}$

With $i=1, i'=0$ we have that $Y_n =1 , Y_{n-1}=0, Y_{n-2}=0$

So based on these conditions $Y_{n+1}$ would be 1 with probability 1/2 from the definition.

If we find a counter example when the probability is not satisfied we can proof that we don't have a Markov Chain.

Let's assume that $j=2, i=1, i'=2$ for this case in order to satisfy the definition then $Y_n =0, Y_{n-1}=1, Y_{n-2}=1$

But on this case that means $X_{n+1}\neq 2$ and on this case the probability $P(X_{n+1}=j| X_n =i, X_{n-1}=i')= 0$ , so we have a counter example and we have that:

$P(X_{n+1} =j| X_n =i, X_{n-1}=i') \neq P(X_{n+1} =j | X_n =i)$ for all $i,i', j$ so then we can conclude that we don't have a Markov chain for this case.

Find the y-intercept for the parabola defined by this equation: y=2x2+x−1

Natalija [7]

Answer:

(0, -1)

Step-by-step explanation:

The c value of the equation represents the y-intercept. c=-1 so the y-intercept must be (0,-1)

The Smiths want to buy a 9 ft. by 12 ft. carpet and center it in a 15 ft. by 20 ft. room.

Maksim231197 [3]

1 inch = 1 foot is the answer. The appropriate scale to use on an 8 1/2 by 11 sheet of paper for a sketch of the room and carpet is 1 inch = 1 foot. The other choices are incorrect because it is not possible for 1/2 inch= 1 foot and it is grammatically wrong when we say 1 inches= 1 foot.

otez555 [7]

Answer: a) $26.55/year

b) $64.13/year

Step-by-step explanation:

a) $7.64 . 1 ft³ . 50 gal . 1 load . 52 week = $26.55

100 ft³ 7.48 gal 1 load 1 week 1 year year

The total cost per year is $26.55

b)$7.64 . 1 ft³ . 17.2 gal . 1 shower . 365 days = $64.13

100 ft³ 7.48 gal 1 shower 1 day 1 year year

The total cost per year is $64.13
