What is the form of the Sum of Cubes identity? O A. 2° +8° = [(a+b)(27 - ab+b7}
O B. a – b = (a - b)(22 +ab+87)
O C. 22 – 2 = (a + b) (2 + ab + }}
O D. 22 +62 = (2-6)(a + ab+8}

step-by-step explanation:

answer: do we write it

step-by-step explanation:

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;
