Answer:

440 ≤ x ≤560

Step-by-step explanation:

|x−500|≤60
Rewrite it as a compound inequality−60≤x−500≤60
Solve for X by adding 500 to each side. -60+500≤x-500+500≤60+500
Leaving you with 440≤x≤560
Answer: The coffee shop is expected to serve a maximum of 560 customers and a minimum of 440 customers per morning.

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 the product written in scientific notation?

wel

Answer is C. Definitely not d right off the bat because both exponents are negative so cross that out. After that its just counting zeros.

Terry has 43 in her checking account....she then writes a check for 62...
43 - 62 = - 19 <==
