Answer:
The correct answer is D
Step-by-step explanation:
As it can be clearly visualized from the graph that the variation is not likely to be 2.0 as at most of the points the difference is not close to 2.0
Hence, The difference is not significant because a difference of 2.0 is not very likely.
Answer:
15/60 or 1/4, which is 25%
Step-by-step explanation:
Answer:
Option D.75°
Step-by-step explanation:
we know that
The sum of the interior angles of a regular dodecagon is equal to
where
n is the number of sides
In this problem
n=12 sides
substitute
Find the measure of each interior angle
Divide the sum of the interior angles by the number of sides
The measure of the angle formed by the radius and the side of a regular dodecagon is half the measure of the interior angle
therefore
The first is going to be, D. & the second question is, C.

Answer:
Step-by-step explanation:
Like terms are ones with the same variable (or set of variables). Here, any x-terms are "like" terms. They are combined by adding their coefficients.
4x +4x +4x +4x = x(4+4+4+4) = 16x
-7x +4 +3x = x(-7+3) +4 = -4x +4
3x +5x +8 = x(3+5) +8 = 8x +8
4x +4x = x(4+4) = 8x
