Write a polynomial function in standard form with the given zeros. x = 3, -1, -7

Choose the correct answer below.

A. f(x) = x3 - 5x² – 17x + 21
B. f(x) = x3 + 5x2 – 17x- 21
C. f(x) = (x - 3)(x + 1)(x + 7)
D. f(x) = (x+3)(x - 1)(x - 7) E. f(x)=- 21 + x3 – 17x + 5x2
F. f(x) = 21 + x3 – 17x - 5x2

< 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

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
