Slope of the line between (3,-2) and (-5,4)

The slope given two ordered pairs is (y2-y1)/(x2-x1)

Plugging in the ordered pairs, we get:

(4-(-2))/(-5-3)

6/-8

-6/8

-3/4

So the slope is -6/8 or -3/4 simplified

Hope this helped!

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;
