Answer:

e=4/100s+200

Step-by-step explanation:

The commission earned in a week is a function or a percentage of the sales. Given that the relationship is in percentage, it means that the commission is the percentage given multiplied by the weekly sales. The sum of the result and $200 earned for the week gives the weekly earning.

Hence if the weekly sales is s,

commission = 4% × s = (4/100)s

Weekly earnings e,

= 200 + (4/100)s      (in $)

That’s the number is written in standard scientific notation?
Nata [24]

Option D: 3.47*10^-7 is the correct answer

Step-by-step explanation:

In order to determine the number written in standard scientific notation, first of all we have to understand how the scientific numbers are written

the scientific numbers are written in the form of:

a*10^n

Here

a is a number between 1 and 10 while the value of n can be only integer (positive or negative)

so,

In the given options:

Option A has a number larger than 10 in place of a so it is not in standard notation

Option B has a number less than 1 in place of a  so it is also not in standard notation

Option C has a number larger than 10 in place of a so it is not in standard notation

Option D is in standard scientific notation as 1<3.47<10 and the power of 10 is integer

Hence,

Option D: 3.47*10^-7 is the correct answer

Exercise 7.3.5 The following is a Markov (migration) matrix for three locations        1 5 1 5 2 5 2 5 2 5 1 5 2 5 2 5 2

Answer:

Both get the same results that is,

\left[\begin{array}{ccc}140\\160\\200\end{array}\right]

Step-by-step explanation:

Given :

\bf M=\left[\begin{array}{ccc}\frac{1}{5}&\frac{1}{5}&\frac{2}{5}\\\frac{2}{5}&\frac{2}{5}&\frac{1}{5}\\\frac{2}{5}&\frac{2}{5}&\frac{2}{5}\end{array}\right]

and initial population,

\bf P=\left[\begin{array}{ccc}130\\300\\70\end{array}\right]

a) - After two times, we will find in each position.

P_2=[P].[M]^2=[P].[M].[M]

M^2=\left[\begin{array}{ccc}\frac{1}{5}&\frac{1}{5}&\frac{2}{5}\\\frac{2}{5}&\frac{2}{5}&\frac{1}{5}\\\frac{2}{5}&\frac{2}{5}&\frac{2}{5}\end{array}\right]\times \left[\begin{array}{ccc}\frac{1}{5}&\frac{1}{5}&\frac{2}{5}\\\frac{2}{5}&\frac{2}{5}&\frac{1}{5}\\\frac{2}{5}&\frac{2}{5}&\frac{2}{5}\end{array}\right]

     =\frac{1}{25} \left[\begin{array}{ccc}7&7&7\\8&8&8\\10&10&10\end{array}\right]

\therefore\;\;\;\;\;\;\;\;\;\;\;P_2=\left[\begin{array}{ccc}7&7&7\\8&8&8\\10&10&10\end{array}\right] \times\left[\begin{array}{ccc}130\\300\\70\end{array}\right] = \left[\begin{array}{ccc}140\\160\\200\end{array}\right]

b) - With in migration process, 500 people are numbered. There will be after a long time,

After\;inifinite\;period=[M]^n.[P]

Then,\;we\;get\;the\;same\;result\;if\;we\;measure [M]^n=\frac{1}{25} \left[\begin{array}{ccc}7&7&7\\8&8&8\\10&10&10\end{array}\right]

                                   =\left[\begin{array}{ccc}140\\160\\200\end{array}\right]
