What is the slope of a line that goes through 0,0 and 5,-1

  slope = -1/5

Step-by-step explanation:

The slope of a line between two points is ...

  slope = (change in y)/(change in x)

  = (-1 -0)/(5 -0) = -1/5

The slope of the line is -1/5.

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;

d is the only accurate one
