Which of the following shows the polynomial below written in descending order?
3x - 5x+ x + 9 + 4x11
O A. x+ 3x9 + 9 + 4x11 - 5x
B. 4x11 + x² + 3x3 – 5x + 9
C. 9 + 4x! + x² + 3x3 - 5x
D. 4x11+ x - 5x+ 9 + 3x3

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

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;

what are the
