nata0808 [166]

Answer:

First option: 10 - (1) = 9

Second option: 10 - 5 + 4 = 5 + 4 = 9

Step-by-step explanation:

(10 -5) -4 = 5 - 4 = 1

Equivalent equation: 10 - 5 - 4 = 1

10 - (5-4) = there would be 2 ways to do this, you can either solve the equation in the bracket first or break it out. Because the sign before the bracket is minus so when you break it out, the minus sign in the bracket would become -- or equal to +

First option: 10 - (1) = 9

Second option: 10 - 5 + 4 = 5 + 4 = 9

Hope this help you:3

Ad libitum [116K]

Answer:

The steady state proportion for the U (uninvolved) fraction is 0.4.

Step-by-step explanation:

This can be modeled as a Markov chain, with two states:

U: uninvolved

M: matched

The transitions probability matrix is:

\begin{pmatrix} &U&M\\U&0.85&0.15\\M&0.10&0.90\end{pmatrix}

The steady state is that satisfies this product of matrixs:

[\pi] \cdot [P]=[\pi]

being π the matrix of steady-state proportions and P the transition matrix.

If we multiply, we have:

(\pi_U,\pi_M)*\begin{pmatrix}0.85&0.15\\0.10&0.90\end{pmatrix}=(\pi_U,\pi_M)

Now we have to solve this equations

0.85\pi_U+0.10\pi_M=\pi_U\\\\0.15\pi_U+0.90\pi_M=\pi_M

We choose one of the equations and solve:

0.85\pi_U+0.10\pi_M=\pi_U\\\\\pi_M=((1-0.85)/0.10)\pi_U=1.5\pi_U\\\\\\\pi_M+\pi_U=1\\\\1.5\pi_U+\pi_U=1\\\\\pi_U=1/2.5=0.4 \\\\ \pi_M=1.5\pi_U=1.5*0.4=0.6

Then, the steady state proportion for the U (uninvolved) fraction is 0.4.

What is d in d • 24= -12
Firdavs [7]

Answer:

The answer is (-1/2)

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • d • 24 = (-12)
<h3><u>To </u><u>Find</u>;</h3>
  • The value of d

So,

24d = -12

Divide both side by 24 we get,

24d/24 = -12/24

d = -1/2

Thus, The value of d is (-1/2)
