Answer:61
Step-by-step explanation:
Its common logic
The population Pa of insect A after t years is given by the equation
Pa = 1.3(1-0.038)^t
while the population Pb of insect B after t years is
Pb = 2.1(1-0.046)^t
We equate the above expressions to find the number of years t it will take the two populations to be equal:
Pa = Pb
1.3(1-0.038)^t = 2.1(1-0.046)^t
1.3(0.962)^t = 2.1(0.954)^t
These are the equations that can be used to determine how long it will be before the populations of the two species are equal.
We can now solve for t:
(0.962)^t / (0.954)^t = 2.1/1.3
(0.962/0.954)^t = 2.1/1.3
After taking the log of both sides of our equation, number of years t is
t = log (2.1/1.3) / log (0.962/0.954)
t = 57 years
Therefore, it will take 57 years for the population of insect A to equal the population of insect B.
Answer:
K would be 375.
Step-by-step explanation:
You take the number you already have and divide it by the new number its giving. (0.06)
Answer:
C. The number of responces
is also 46
Step-by-step explanation:
Note that:
means both p and q must hold;
means either p or q must hold.
From the diagram,
- the number of responses
is 46; - the number of responces
is also 46; - the number of responces
is 0; - the number of responces which are neuther p nor q is 20.
So, you can state that the correct answer is C
