1. X=3 since the graph seems to be going in a straight direction on the y axis
2. Y=2 since the graph seems to be going in a straight direction on the x axis
3. X=-2 since the graph seems to be going in a straight direction on the y axis
Answer:
B. 12
Step-by-step explanation:
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:
a=5
Step-by-step explanation:
15=3a
1. You need to try to get the variable alone, in this case its a
2. So you divide 15 by 3
3. That will give you 5=a or a=5
I think the answer is 43.8.
