Answer: the value of the diversity index D for the population is 0.42
Step-by-step explanation:
Given that; population of the two species are
p1 = 30% = 0.3 (snapping turtle)
p2 = 70% = 0.7 ( box turtle)
so if two (2) organisms are picked, then they can be different from each other ( i.e Event E) under following two scenarios
E1 → First organism selected from p1 and second organism selected from p2
E2 → First organism selected from p2 and second organism selected from p1
which means we are observing the different orders in which the organisms can be picked.
So the probability of event E = the sum of probabilities of events E1 and E2.
which is;
D = P(E) = P(E1) + P(E2)
= P1×P2 + P2×P1
= 2P1P2
so we substitute
D = 2 × 0.3 × 0.7
D = 0.42
Therefore the value of the diversity index D for the population is 0.42
Answer:
(-2, -1)
Step-by-step explanation:
-2 is x
-1 is y

86 divided by 10
Which equals 8.6
8.6 times 16
The answer is 137.6
Answer and Step-by-step explanation:
For this triangle, to find x, we will use the cosine trigonometric function.
cosine functions look like this:
(The weird looking symbol is called theta, and represents an angle measurement)
Plug in the values into the equation.
cos(42) = 
Multiply both sides by 15.
15(cos(42)) = x

Answer:
(-7)(-1.2)=8.4
(7)(-1.2)=-8.4
(2.5)(-2)=-5
(-2 1/2)(2)=5
Step-by-step explanation:
First,a negative multiplied by another negative will have a product that is positive.
Also, -2 1/2 is the same as -2.5
