The annual profits for a company are given in the following table, where x represents the number of years since 1995, and y represents the profit in thousands of dollars.
Write the linear regression equation that represents this set of data, rounding all
coefficients to the nearest hundredth. Using this equation, estimate the calendar year
in which the profits would reach 431 thousand dollars.

ian gone lie this got me confused

step-by-step explanation:

< 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

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
