Hello,

x + 2 = 6

x = 6 - 2

x = 4

Bye :)

Subtract 2 to both sides

6 = x + 2 it will then become

6 - 2 = x + 2 - 2

4 = x

State the y-coordinate of the y-intercept for the function below.

Molodets [167]

When y intercpets, x = 0
so here,

ƒ(x)=x^3-x^2-x+1
ƒ(x)=(0)^3-(0)^2-0+1
ƒ(x)= +1

Let P = 0.50.30.50.7 be the transition matrix for a Markov chain with two states. Let x0 = 0.50.5 be the initial state vector fo

Answer:

Probability distribution vector = $\left(\begin{array}{c}0.375\\ 0.625 \end{array} \right)$

Step-By-Step Explanation

If $P=\left(\begin{array}{cc}0.5&0.3\\ 0.5&0.7 \end{array} \right)$ is the transition matrix for a Markov chain with two states.

$x_{0}=\left(\begin{array}{c}0.5\\ 0.5 \end{array} \right)$ be the initial state vector for the population.

$X_{1}=P x_{0}=\left(\begin{array}{cc}0.5&0.3\\ 0.5&0.7 \end{array} \right) \left(\begin{array}{c}0.5\\ 0.5 \end{array} \right) =\left(\begin{array}{c}0.4\\ 0.6 \end{array} \right)$

$X_{2}=P^{2} x_{0}=\left(\begin{array}{c}0.38\\ 0.62 \end{array} \right)$

$X_{3}=P^{3} x_{0}=\left(\begin{array}{c}0.38\\ 0.62 \end{array} \right)$

$X_{30}=P^{30} x_{0}=\left(\begin{array}{c}0.37499\\ 0.625 \end{array} \right)$

In the long run, the probability distribution vector Xm approaches the probability distribution vector $\left(\begin{array}{c}0.375\\ 0.625 \end{array} \right)$ .

This is called the steady-state (or limiting,) distribution vector.

Answer:

$T_{23}=-153$

Step-by-step explanation:

$T_{23}=a+(n-1)d\\$

$=a+(23-1)d=a+22d$

Now $a=-21$ and

$d=-27-(-21)\\=-6$

So $T_{23}==21+((22)6\times-1)$

$=-153$

The orbital period, P, of a planet and the planet’s distance from the sun, a, in astronomical units is related by the formula P=

Elodia [21]

Answer: 9.54731702 astronomical units

Step-by-step explanation:

Given: The orbital period, P, of a planet and the planet’s distance from the sun, a, in astronomical units is related by the formula $P=a^{\frac{3}{2}$ .

Saturn’s orbital period P = 29.5 years

Substitute this value in the equation above, we get

$29.5=a^{\frac{3}{2}}\\\Rightarrow(29.5)^{\frac{2}{3}}=a\\\Rightarrow\ a=9.54731702\text{ astronomical units}$

Hence, its distance from the sun = 9.54731702 astronomical units.

How many one inch cubes do you need to create an edge with a length of 5 inches

Bingel [31]

Actually you would need 125 inches cube:

5 inches of length × 5 inches of height × 5 inches of width which equals to 125 inches cube !

I hope you understood my brief explanation. And please consider marking this awnser as Branliest. Thank you ! :)
