Suppose you own a publishing company that sells political non-fiction books to a large retailer for $8.25 per book. The daily cost of the company
to print x books is C(x) = $8.25x + 1500 dollars. If the marginal cost of
producing books doubles but the fixed cost decreased by 30%, then the
new cost function will be represented by function K(x). Write K(x) as a
transformation of C(x).

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

it is x=-4

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;
