Answer:
example of the contact hypothesis
Explanation:
we know here that student find roommate and as they get to know each other
and they are able to overcome their initial prejudices
so this is an example of contact hypothesis , because
contact hypothesis is hold that contact between people of different groups tends to reduce
and whatever inter groups negative attitudes may be exist
there are greater the contact and the less the antipathy
so we can say here this is an example of the contact hypothesis
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
