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.
Answer:
x = 53 degrees
Step-by-step explanation:
Alternate exterior angles are equal if two parallel lines are cut by a transversal.
If m and n are parallel, then
3x-28 = 2x+25
Subtract 2x from each side.
3x-28-2x = 2x+25-2x
x-28 =25
Add 28 to each side.
x-28+28 = 25+28
x = 53
Answer:
x: C
y: A
z:
Step-by-step explanation:
In a 45-45-90 triangle, the hypotenuse is larger than either of the legs by a factor of 
. The length of x is therefore:
In a 30-60-90 triangle, the longer leg is larger than the shorter leg by a factor of 
. Therefore:
The hypotenuse of the 30-60-90 triangle is twice larger than the smallest leg, so it has a length of 
.
By the pythagorean theorem, you can find z+y:
Hope this helps!
Answer:
its 12
Step-by-step explanation:
you just simply divide 16x3/4 and you should get 12
