Find the distance between A(-6, -4)and B(9, -12)

17 units

Step-by-step explanation:

Calculate the distance using the distance formula

d =

with (x₁, y₁ ) = A(- 6, - 4) and (x₂, y₂ ) = B(9, - 12)

AB =

     =

     =

      =

      = 17 units

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;
