Step-by-step explanation:
formulae=H×L×W so....5×9×4=180
Answer:
Slope
Step-by-step explanation:
In the regression equation y=a+bx, y is dependent variable and x is independent variable. It means that due to change in x the y changes respectively. The "a" is intercept of the model and it shows the value of y when x is zero. The "b" is the slope of the model and it depicts the change in y due to unit change in x. The positive value of b means that as the x increases y also increases and as the x decreases y also decreases. The negative value of b means that as the x decreases y increases and as the x increases the y decreases.The sign of b shows the type of relationship between independent and dependent variable.
Answer:
The answer is Graph X.
- Always start by isolating the variable \color{red}y on the left side of the inequality.
- Change the inequality to equality symbol.
- Graph the boundary line from step 2 in the XY-plane.
- The last step is to shade one side or region of the boundary line.
