Answer:
<u>A) Matched pairs design</u>
<u>Step-by-step explanation:</u>
In<em> </em><em>experimental design</em>, the match pairs experimental design is one that often involves only two treatment conditions; which in this case are the 'refrigerated and the room temperature battery storage types'.
Thus, these two treatment conditions form a matched pair because we are told that 10 fully charged batteries are placed into each type of storage.
(x^3 - y^3)(x^3 + y^3)
You can get this by factoring based on the a^2 - b^2 model
X^2+x+8 is the answer unless you need it factored
1.02 is the answer to your question
Y = kx
Where 'k' is the constant of variation.
y = 4x means that 4 is the constant of variation.
Answer: 4
