Answer:
The correct answer is - a. learn about your audience.
Explanation:
Observing, collecting data, doing surveys and making inferences all are examples to know about the audience how they react, what they like, what influences them. These all research methods are very useful to learn about an audience.
For analyzing diversity they must be a comparison of types of diversity present. Observation, surveys, interview or making inferences are not something can be used in make presentational adaptations.

Answer:
stop being so judgmental and getting along with our differences.
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
