Answer:
Choice A (older trees are generally taller than younger trees)
Step-by-step explanation:
As you increase the x value, the y value tends to increase as well. Choice B is incorrect because the points are clustered together in a linear fashion, showing correlation. Choice C is incorrect because the fact that they are clustered around a line of best fit shows high correlation. Choice D is incorrect because a negative correlation coefficient would mean the y decreases as x increases.
Step-by-step explanation:
This is the answer for I)
Just use Pythagorean theorem formula to the tye hypotenuse.
Answer:
x = 13.48
Step-by-step explanation:
Given that,
Angle, 
base, b = x
Hypotenuse, H = 15
We need to find the measure of x. It can be solved using trigonometry i.e.

Put all the values,

So, the value of x is equal to 13.48.
