Select the correct statement about the function represented by the table
a. it is an exponential function because the y-values increase by an
equal factor over equal intervals of x-values.
b. it is an exponential function because the factor between each x-
and y-value is constant.
c. it is a linear function because the difference between each x- and
y value is constant.
d. it is a linear function because the y-values increase by an equal
difference over equal intervals of x-values.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

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;
