Answer:
We are given the correlation between height and weight for adults is 0.40.
We need to find the proportion of the variability in weight that can be explained by the relationship with height.
We know that coefficient of determination or R-square measures the proportion or percent of variability in dependent variable that can be explained by the relationship with independent variable. There the coefficient of determination is given below:
Therefore, the 0.16 or 16% of the variability in weight can be explained by the relationship with height
Answer:
D
Step-by-step explanation:
That is where the line meets.
Y2-y1 / x2-x1 i think. not sure if that's correct
The second answer I believe. Sorry if I am wrong.
Answer:
The expressions that show the value of q are
1) 
2) 
3) 
4) 
5) 
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
case A)
In the right triangle of the figure
Applying the Pythagoras Theorem
case B)
In the right triangle of the figure
solve for q
case C)
In the right triangle of the figure
solve for q
case D)
In a right triangle
if 
then
