Based on data collected over several sessions, a statistically minded trainer of office typists modeled the linear relationship between the number of hours of training a typist receives and the typist's speed (in words per minute) with the equation ModifyingAbove speed with caret equals 10.9 plus 5.7 (hour ). After some training, one of the typists was told that the speed he attained had a residual of 4.1 words per minute. How should he interpret this?

< 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
