Answer: 81% of the variance in dependent variable is explained by this correlation .
Step-by-step explanation:
For X = Independent variable and Y=dependent variable,
If r= correlation coefficient , then we say 
<em> </em>of the<em> </em>variance in Y is explained by Variable X.
Given: r= 0.90
So, 81% of the variance in dependent variable is explained by this correlation .
Answer:
-21-24/x
Step-by-step explanation:
f(x) is a function on his own which is f(x)=7x+8
we multiple it with another function which is g(x)=-1/x
that gives us (g*f)=-7-8/x
then multiple it by 3 we have -21-24x

Answer:
24,840 cubic inches
Step-by-step explanation:
18 x 30 = 540 - rectangle house front surface area
540 + .5(30 x 10) = 690 - triangle house front surface area
690 x 36 = 24,840 - (rectangle + triangle surface area) x depth
