Many times, multiple variables can be correlated, affecting the outcome of the dependent variable. Describe, in detail, the process for determining if more than one variable contributes to the outcome of a single dependent variable. How accurate is a regression analysis and how do you know? What attributes of the analysis will determine whether the analysis is accurate and to what extent? Can inaccurate regression analyses be used to an analyzer’s benefit? Explain in detail

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
