If C(x) is the cost of producing x units of a commodity, then the average cost per unit is c(x) = C(x) x . Consider the cost function C(x) given below. (Round your answers to the nearest cent.) C(x) = 16,000 + 140x + 4x3/2 (a) Find the total cost (in dollars) at a production level of 1,000 units.
(b) Find the average cost (in dollars per unit) at a production level of 1,000 units.
(c) Find the marginal cost (in dollars per unit) at a production level of 1,000 units.
(d) Find the production level (in units) that will minimize the average cost.
(e) What is the minimum average cost (in dollars per unit)?

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;

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
