Answer: The post-reinforcement pause.
Explanation:
The post-reinforcement pause occurs when the delivery of a reinforcer on fixed-ratio and fixed interval schedule of reinforcement. When he considers not to do anything after having so much before him this behavioural type is known as post-reinforcement pause
The Enlightenment was an<span> eighteenth-century European philosophical movement that emphasized the preeminence of reason rather than faith.</span>
The answer is a desirable outcome. In an approach-approach, the individual is faced with the necessity of making a choice between two (or more) desirable goals. Since both goals are desirable, this is the least worrying situation. "Shall I fly or take a boat to Europe?" might be easily determined if both means of travel are seen as pleasurable. Such situations produce a state of unstable equilibrium. As soon as one goal is approached, its desirability increases and completely dominates, thereby making the choice easy. The choice becomes easier the closer one moves toward either goal. Another example is when a person pick between two attractive and practicable careers, may lead to some indecisiveness but rarely to great distress. A person chooses the most convenient goal that results to a desirable outcome.
Answer:
From the first generation = 2 ancestors.
From the second generation = 4 ancestors or (2)^2 ancestors.
From the third generation = 8 ancestors or (2)^3 ancestors.
We can infer from the given data, each consecutive generation possesses twice the number of members.
The sum will be:
2 + 4 + 8 + 16 + ... + (2)^39
To evaluate the amount of ancestors, let's employ the formula for the summation of a geometric sequence.
(Geometric sequence shows the sequence of numbers that varies by a specific factor. This factor is specifically known as a ratio).
Formula for Geometric sequence:
S = (a1) × 1 - (r)^n
--------------------------
1 - r
Take:
S -> sum
a1 -> first member of a sequence
r -> ratio
n -> number of elements
In this question, our:
a1 = 2; r = 2; and n = 39
S = (2) × 1 - (2)^39
-------------------------
1 - 2
S = 1,099,511,627,777
