All you have to do is write the function!
sasho [114]

Answer:

The function that represents the average cost in dollars of saleable software CD is given as follows;

f(x) = 500,020/x + 0.10

Step-by-step explanation:

The given parameters are;

The cost of manufacture of each software CD = $0.10

The development cost to produce the CD = $500,000

The number of CDs that are not sold = The first 200 CDs

The total cost of production. 'C', of the the CD is given as follows;

C = $500,000 + $0.10×200  = $500,020

The function, 'f' for the average cost in dollars of a saleable software CD where 'x' is the number of saleable software CDs is given as follows;

f(x) = (C + 0.10·x)/x = C/x + 0.10

∴ f(x) = 500,020/x + 0.10.

Which of the following describes the function x^3 − 8?
klemol [59]

Answer:

(A)

Step-by-step explanation:

A)The degree of the function is odd, so the ends of the graph continue in opposite directions. Because the leading coefficient is positive, the left side of the graph continues down the coordinate plane and the right side continues upward.

The president of a bowling league wanted to estimate the average highest bowling score of all its 200 members. Instead of survey
Nikolay [14]

Answer:


Step-by-step explanation:

In statistics, whenever full population cannot be surveyed, a random sample can be taken and from the observations population behaviour can be estimated.

Here given that there are 200 members.  Instead of collecting data from all 200, 20 members are randomly taken.

The sample mean x bar can be estimated to give an idea the population mean also.

ACcording to central value theorem, means of different samples will follow a distribution with mean = population mean and std deviation = std dev of sample/square root of n

Hence we fix confidence interval as Mean + or - Z critical * std error

This gives us an idea about within which means will lie for different samples and hence give an idea about population mean also.
