What is the interquartile range (iqr) for the data set? 12, 14, 15, 18, 22, 24, 28, 31, 35

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

< 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
