Answer:
Collision theory, theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another.
It tells you on the side of the y axis Amount Spent (in dollars) D is the only one that says anything about amount spent.
Answer: b. The sampling distribution of the proportion of damaged trees is approximately Normal
Step-by-step explanation:
The sample mean is an unbiased estimator of the true (unknown) population mean and The sampling distribution shows how the sample mean will vary among repeated samples. In the case above the samples are selected at random from a normally distributed population, and the number of samples selected (n=100) is a bit large therefore the sampling distribution will be approximately normal.
Answer:
see explanation
Step-by-step explanation:
Not sure quite what you are asking, but
Using the trigonometric identity
cos² x = 1 - sin²x, then
cos²x - sin²x
= 1 - sin²x - sin²x
= 1 - 2sin²x
Thus
cos²30° - sin²30° = 1 - 2sin²30°
with that template in mind, let's see
so, the parent equation could be
y = x² ====> y = A(x + C)² + D
shrink by 3, A = 3
left 4, C = +4
down 9, D = 9
