3- quiz
line k passes through the point (-3,-5) and has a slope of -1/3. what is the
equation for line k?

y+5=-1/3(x+3)

Step-by-step explanation:

y-y1=m(x-x1)

y-(-5)=-1/3(x-(-3))

y+5=-1/3(x+3)

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;
