I promise brainliest 5 stars and a thank you to the first to answer Choose the graph that best represents the solution to the system of equations. y = x y = -x + 1 one solution: (1 over 2 ,1 over 2 ) infinitely many solutions one solution: (-1 over 2 , -1 over 2 ) no solution .

the answer is a

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;

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4
