The table shows the number of glass bottles of different colors in a shelf. a fair coin is shown below the table. red: 9 blue: 1 green: 6 purple: 4 danny selects a glass bottle from the shelf randomly without looking and then tosses the fair coin. what is the probability that he will select a purple glass bottle and that the coin will land heads up? a. 1/10 b. 1/8 c. 1/6 d. 1/5

< 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

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
