Answer:
Graph B
Step-by-step explanation:
we know that
The graph that represent the situation
As x increases, y increases
Is the graph B or the graph C
but
Graph B represent a moderate coefficient of correlation r (-0.5 to -0.3 or 0.3 to 0.5)
Graph C represent a strong coefficient of correlation r (-1.0 to -0.5 or 1.0 to 0.5)
In this problem we have r=0.42
so
The coefficient of correlation is Moderate
therefore
The answer is the Graph B
If we assume the hypotenuse is of side length 5:
a^2+b^2=c^2
3^2+b^2=5^2
9+b^2=25
b^2=16
b=4
If the hypotenuse is the unknown:
a^2+b^2=c^2
3^2+5^2=c^2
9+25=c^2
c^2=34
c=(34)^(1/2)
Answer:
4a) The sides are not scaled up equally for the sides. Plus, B is not a right triangle since it does not satisfy the pythogorean theorem.
4b) 6, 8, 10
