Answer:
A. Symmetric
Step-by-step explanation:
I expect the histogram be symmetric because, the trees are <em>same </em>species and all are planted at the <em>same time</em>.
There is no tree treated differently during planting or affected by an isolated factor.
Therefore, we should expect the differences in the height of the trees has a normal distribution.
I need options but so you know which one it is: it is the one with a number followed by an x (or it could just be x)
Hope this helps :)
You can just do it by having enough building blocks lol
Answer:
Xeno jumped 1 2/3 in
Step-by-step explanation:
if Mai jumped 3 times higher than Priya dividing Mai's 14 by 3 would get Priya's height. Then by subtracting 3 from Priya's height, which is 4 2/3, you get Xeno's height which is 1 2/3 in
-2x+1=-x^2+4
X^2 - 2X + 1 - 4 =0
X^2-2X-3=0
discriminant= (-2)^2 - 4(-3)(1)
=16
D1 = {-(-2)+√16}/2
D1=(2+4)/2
=6/2
D1=3.
D2={-(-2)-√16}/2
=(2-4)/2
=-2/2
D2= -1
the solutions are {-1 ; 3 }
so A) x= -1,3
