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:
The number is 72
Step-by-step explanation:
2/3*27 = 2*9 = 18
so 18 = 25%
25% = 1/4
so 1/4 = 18/?
so ? = 18*4 = 72
Hello!
GCF, or greatest common factor, is the greatest factor shared between two numbers. (A factor is something which you can divide a number by to get a whole number)
To do this, first list out all the factors of 21 and 25. (There are other methods to do this, but, this method will work for smaller numbers)
21: 1, 3, 7, 21
25: 1, 5, 25
As you can see, the greatest factor shared between them is the number 1.
Therefore, the GCF of 21 and 25 is 1.
Hope this helps!
(Side note: a better method to do this for larger numbers is to list out the prime factorization for each number, then find all the numbers in common, and multiply)
D and E because they are both colder than -10
