Find the midpoint of the line segment with endpoints (-9,-1,) and (7,0)

The midpoint is;

(-1,-0.5)

Step-by-step explanation:

To do this, we shall use the midpoint formula

That would be;

(x,y) = (x1 + x2)/2 , (y1 + y2)/2

(x1,y1) = (-9,-1)

(x2,y2) = (7,0)

(x,y)

= (7-9)/2 , (0-1)/2

= -2/2 , -1/2

= (-1, -0.5)

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;
