Answer:
C. a third variable, such as students' home environment, must have caused students to both drink more non-diet soda and engage in aggressive acts
Explanation:
From the question, we are informed about An observational study that was conducted in inner-city Boston approximately four years ago demonstrated that high-school students who consumed more than five cans of non-diet soda every week were between 9 and 15-percent likelier to engage in an aggressive act compared with counterparts who drank less non- diet soda. In this case, we can reliably conclude that a third variable, such as students' home environment, must have caused students to both drink more non-diet soda and engage in aggressive acts.
Observational studies can be regarded as studies whereby
researchers make observation about different effect of factors such as
risk factor, home, as well as environment and diagnostic test that affects the experiment. In observational studies Variables are very crucial, A variable can be anything that that is liable to change, it can change and it can be changed as well. They are factors which the observer can manipulate or control for when carrying out experiments.
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
Answer:
Compromise
Explanation:
According to my research on intercultural marriage styles, I can say that based on the information provided within the question Roger and Adair have probably used the Compromise style of interaction. This can be said because both Roger and Adair have decided to give up certain aspects of their own cultures in order to make the other happier and live a happy marriage, this is called compromising.

Explanation:
Ancient Greek warships are known for their distinct features, which were large with three towns of oars and multiple sails. Because of these features, they were called "Triremes."
It is generally believed to be faster and deadlier compared to other warships at that period. It was also believed that at some point, Greek had about 300 of this particular warship in their arsenal
