Answer:

D;2/5

Step-by-step explanation:

Count how many points (lines) are there from 0-1.

After, count how many points (lines) are form 0-the red dot.

You get 4/10 (4 is the point, out of ten because it is the total)

Simplify: 4/2=2;10/2=5

This is the complete list of proper factors of a number<br>what is the number

creativ13 [48]

The factors are all the possible things you would multiply to get the number. So finding the 2 middle numbers, in this case is 21 and 28 and multiplying them, you get 588. If you're not sure if that's right, take the number on the left or right of the 2 middle numbers, 14 and 42. The product of these 2 numbers are also 588. So your number is 588.

Identify the 12th term of a geometric sequence where a1 = 8 and a6 = −8,192.

vodka [1.7K]

Geometric sequence
$a_{n}=a_{1}*r^{n-1}$
r=common ratio
a1=first term
find r

a1=8
a6=-8192
$-8192=a_{6}=8*r^{6-1}$
$-8192=8*r^{5}$
divide both sides by 8
$-1024=8*r^{5}$
take 5th root of both sides
-4=r
sub
$a_{12}=8*(-4)^{12-1}$
$a_{12}=8*(-4)^{11}$
$a_{12}=8*-4194304$
$a_{12}=-33554432$

I need help with this practice problem solving The subject is : biodiversity index I will send an additional picture that goes a

snow_lady [41]

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.
