If we are given a function and it is raised to the second power, why is it still considered a function even though functions are supposed to be raised to the first power?

lol we need to see what the question is asking about

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;

i have no clue what you just said. write a question in english?

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
