The residents of a certain dormitory have collected the following data: People who live in the dorm can be classified as either

Stella [2.4K]

Answer:

the steady-state percentage of residents who are uninvolved is 0.5

Step-by-step explanation:

Given the data in the question;

let N represent total number of people in the dormitory

I represent people involved in a relationship

and U represent people uninvolved in a relationship.

N = I + U

I = N - U ------ let this be equation 1

Rate of Uninvolved = U/N

now, given that rate of break ups B = 15% every month = 0.15

rate of entering into relationship R = 15% every month = 0.15

Now, the steady state condition is;

RU = BI ------- let this be equation 2

such that uninvolved rate is constant.

we input equation 1 into 2;

RU = B( N - U )

we divide both sides by N

RU/N = B( N/N - U/N )

RU/N = B( 1 - U/N )

U/N = B / (B + R)

so we substitute

U/N = 0.15 / (0.15 + 0.15)

U/N = 0.15 / 0.3

U/N = 0.5

Therefore, the steady-state percentage of residents who are uninvolved is 0.5

Simplify the following rational expression

MatroZZZ [7]

Answer:

The value of k for the expression to be undefined is 9 .

Step-by-step explanation:

Given as :

The rational expression is written in the form

$\dfrac{5k^{2}-50k+45}{k^{2}-18k+81}$

Now, according to question

The expression to be undefined , denominator should be 0

<u>As, $\frac{1}{0}$ is infinite ( ∞ ) term and it is undefined , so for expression to be undefined , the denominator should be 0</u>

∴ k² - 18 k + 81 = 0

Or, k² - 9 k - 9 k + 81 = 0

Or, k ( k - 9 ) - 9 ( k - 9) = 0

Or, ( k - 9 ) ( k - 9 ) = 0

Or, ( k - 9 ) = 0 , ( k - 9 ) = 0

∴ k = 9

So, The value of k = 9

Hence The value of k for the expression to be undefined is 9 . Answer
