What is the quotient of (x4 + 10x3 + 21x2 + 6x – 8) ÷ (x + 2)? Question 8 options: A) x3 + 8x2 + 5x – 4 + 2∕x + 2 B) x3 + 8x2 + 5x + 4 C) x3 + 8x2 + 5x – 4 + 2∕x - 2 D) x3 + 8x2 + 5x – 4

C

Step-by-step explanation: Hope this help :D

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

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;
