Miranda just got an after-school job at a kiosk. She’s planning out how much time she needs for her job, and how much time she needs for school. She wants to work at least 10 hours a week at
the kiosk, and at least 12 hours a week on homework/
studying. After deducting time in school, Miranda has about 36 hours of free-time a week (including weekends). What is the feasible region for her schedule?

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

mean, 40.6

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;
