If yhe product of two zeroes of polynomial 2x^3+x^2-5x-6 is 3, then find its third zero.

1

Step-by-step explanation:

If a cubic polynomial ax³ + bx² + cx + d has three zeros α, β, and γ, then the product of the zeros is -d/a.

αβγ = -d/a

a = 2, d = -6, and αβ = 3.

3γ = 3

γ = 1

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;

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784
