Answer: the value of the diversity index D is Zero (0)

Step-by-step explanation:

Just as the meaning of diversity index is boldly explained in the question, it is the probability that randomly selected organism from a population are from a different species.

Now if the organisms are all from the same species in a population  then it is impossible to select two organisms from different species.

That is, we can never select two organisms that are not from the same species.

Hence, we cant fulfil or meet the definition of diversity index .

Therefore in this situation the value of our diversity index D will be exactly zero, D = 0.

f(x)=13|x-5|-6 is the equation represented by all the operations.

<u>Step-by-step explanation:</u>

The given function is

f(x)=|x|

It is vertically compressed by a factor of 13 then the function becomes,

f(x)=13|x|

It shifted down 6 units, then the function becomes,

\mathbf{f}(\mathbf{x})=\mathbf{1 3}|\boldsymbol{x}|-\boldsymbol{6}

It shifted right by 5 units then the function becomes,

f(x)=13|x-5|-6

Thus the resultant equation thus obtained is  f(x)=13|x-5|-6

13. Write an equation for the given function given the amplitude, period, phase shift, and vertical shift.
aev [14]

Answer:

y=4sin(\frac{\pi}{2} x+\pi)-2

Step-by-step explanation:

The equation of a periodic  function is in the form:

y = Asin(Bx + C) + D

Where A = amplitude, B = 2π / period, D = vertical shift, phase shift = -C / B.

Given that:

amplitude: 4, period 4 phase shift = vertical shift = -2

Hence:

A = amplitude = 4, B = 2π / period = 2π / 4 = π / 2, D = vertical shift = -2.

Phase shift = -C / B

C = -phase shift * B = - * -2 * π / 2 = π.

Therefore substituting gives:

y=4sin(\frac{\pi}{2} x+\pi)-2
