The measurement of the height of 600 students of a college is normally distributed with a mean of 175 cm and a standard deviation of 5 cm. what percent of students are between 180 cm in 185 cm in height?
a. 12.5
b. 13.5
c. 34
d. 68

< 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:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

no
