Rewrite the polynomial in the form ax + by + c and then identify the values of a, b, and c. x+4+y/8

Step-by-step explanation:

x+4+y/8

= 1(x) + 1/8(y) +4

a=1

b= 1/8

c = 4

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;

nope.   happens to me as well.
