Samuel is working two summer jobs, making $19 per hour lifeguarding and making
$8 per hour walking dogs. In a given week, he can work no more than 10 total hours
and must earn a minimum of $120. Also, he must work at least 6 hours lifeguarding.
If x represents the number of hours lifeguarding and y represents the number of
hours walking dogs, write and solve a system of inequalities graphically and
determine one possible solution.

answer: idk

step-by-step explanation:

can you make your screen more see able?

then i might be able to .

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;

answer: i wpould go with c
