the photography club decided to go on a field trip to the andy warhol museum. they had to break into smaller groups once they got there. the first group had 25 students and 2 teachers. their cost was $97.50. the second group had 32 students and 3 teachers. their cost was $127. what is the cost of each student and each teacher?

part a: define your variables

part b: write a system of equations to represent this situation

part c: solve the system of equations you wrote in part b.

part d: interpret what your answer means in context to this situation.

answer all parts. you for your : )

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;

hello, there is a new name in town and that's the human spider!

answer: d.) the total number of protons and neutrons is 15

merry christmas!

your friendly neighborhood human spider! .
