8) The larger the variability number the greater the spread of the numbers in a data set. True or False

True

Step-by-step explanation:

The variance of a data set gives you a rough idea of how spread out your data is. A small number for the variance means your data set is tightly clustered together and a large number means the values are more spread apart.

< 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
