Line g goes through (8,2 )and ( -12,-23) write in point slope form\

y-2=5/4(x-8)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-23-2)/(-12-8)

m=-25/-20

m=25/20

m=5/4

y-y1=m(x-x1)

y-2=5/4(x-8)

the answer is ! ?

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;
