Answer:
A. Yes -- Aricka drew the line correctly because the line is decreasing with data points above and below the trend line.
Explanation:
This is what is known as having a line of best fit. The data points should <em>at least</em> <em>nearly</em> be evenly distributed on both sides of the line for it to be a good line of best fit. You should also make sure that you have at least a few points TOUCHING the line. This is a majour part of having a line of best fit.

Answer:Hint:
the remainder is 2.
Step-by-step explanation:
23≡1 mod 7 and 33≡−1 mod 7.
Edit: The only thing you need from the modular arithmetic is that
a⋅b mod 7=(a mod 7)(b mod 7) mod 7,
meaning the remainder of a product is the remainder of the product of remainders. This is self-evident as a⋅b must have the same remainder as (a−7k)⋅(b−7l).
Since exponentiation is just repeated multiplication, we can write
230⋅320=(23)10⋅(33)6⋅32≡110⋅(−1)6⋅9=9
