Write both sides as powers of $e$ :

$\ln(x+4)=-1\implies e^{\ln(x+4)}=e^{-1}\implies x+4=e^{-1}$

since $b^{\log_ba}=a$ . Then

$x=e^{-1}-4\approx-3.63$

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.
