Your boss wants you to analyze the relationship between the company's monthly operating costs and the current cost driver she has chosen. You run a regression analysis and receive the following information:

Intercept Coefficient = 653,434
X Variable 1 Coefficient 5.76
R-square= 0.3784

What is your company's monthly cost equation?

A. y = $0.38x + $576
B. y = $653,434x + $5.76
C. y = $5.76x + $653,434
D. y = $0.38% + $653,434

With reference to the solutions, following things may be noted1) homogeneous solutions comprises of single phase.2) heterogeneous solution comprises of more than one phase.3) in colloidal solution, solute is evenly distributed in solvent. in such system, it is difficult to separate solute and solvent.4) in suspension, there is an uneven distribution of solute in solvent. in such system, solute and solvent gets separated on standing long.    blood is a homogeneous and colloidal solution,salad dressing is a heterogeneous and suspension solution.
