Answer:
13
Step-by-step explanation:
The slope of the regression shows the average increase in response variable due to unit increase in explanatory variable. The regression equation of structure y=a+bx has slope=b.
The given regression equation y^=85+13x shows that the slope in the given equation is b=13. The response variable is amount of natural gas is used and explanatory variable is outside temperature in this case.
So, we can say that on increase of every unit of degree day the amount of gas used increase by 13 cubic feet.
Let's find the area of one parallelogram piece.
Formula:
Plug in what we know:
Multiply:
This is the area of one parallelogram piece, so multiply by 25 to find out the area of the entire quilt.
