Answer:

d. 4

Step-by-step explanation:

The degree of freedom is the amount of independent data set used to calculate an estimate. The degree of freedom is quite different from the sample size (n). It is calculated by subtracting one(1) from the total value of the data set (sample size (n)).

From the information given:

The sample size is the number of people in the same group

sample size n = 5

degree of freedom = n - 1

= 5 - 1

= 4

iris [78.8K]

Answer:  x - 5

Step-by-step explanation:

Since, the area of the rectangle = x^2 - 25=(x+5)(x-5)

Length of the rectangle = x+5

Let the width of the rectangle = b

Thus, the area of the rectangle = (x+5)\times b

⇒ (x+5)\times b=(x+5)(x-5)

⇒  b=\frac{(x+5)(x-5)}{(x+5)}

⇒ b=x-5

Therefore, the expression that shows the width of the rectangle = x-5

ANSWER

Biodiversity index = 0.096

EXPLANATION

Given 7 different organisms with their individual numbers.

Biodiversity Index is:

\text{  }\frac{Total\text{ number of species}}{Total\text{ number of individuals in the area}}

i.e:

\begin{gathered} Biodiversity\text{ Index = }\frac{7}{15+2+30+1+4+16+5} \\ \text{ = }\frac{7}{73} \\ \text{ = 0.09589} \end{gathered}

Hence, the Biodiversity Index of Fraya's local park is 0.096. This is a low biodiversity since it's closer to 0.
