The Midpoint of Jk is M(6,3). One endpoint is J(14,9). Find the coordinates of endpoint K.

(-2,-3)

Step-by-step explanation:

If the midpoint is located at (6,3), we know that it will be equally apart from the endpoints. So, from endpoint J, it is 8 units away (x), and 6 units away(y). So, the endpoint K would be (6-8,3-6) = (-2,-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;
