A company is trying to develop a computer algorithm to predict whether a
customer will make a purchase of $100 or more in an online store based on the
customer's browsing behavior and various characteristics about the customer. As
the company collects more customer data, it updates its algorithm to make it
more accurate. The graph below shows the algorithm's error rate for various
amounts of customer data. Which conclusion can the company make about the
error rate for this algorithm?
The error rate stabilizes and approaches an error rate of 2.5%.
,The average cost in dollars, A( x), to produce x cell phone screen covers is given by
the graph below. What happens to the average cost as more and more covers are
produced?
The average cost reduces to about $2 per cover.
The volume of calls, V( h), at a particular customer service center can be written
as a function of the number of hours after opening each day, h. What would the
ordered pair (6,8) represent for this function?
There were 8 calls 6 hours after opening.
A company has developed two functions, L( t) and M( t), that determine the least
amount and most amount, respectively, of revenue it will make in any given
month in dollars (with t = 1 corresponding to January). What can the company

In February, it will make between $3,000 and $5,000.
A server at a restaurant has realized that tips, T, in dollars are related to the
number of hours, h, that have been worked on any given day. Tips can be

A local business is looking to become a franchise. The company wants to predict
the number of franchises, F, given a certain number of years, Y. This prediction is

In 5 years, there will be 10 open stores.
A bank begins a marketing campaign to increase its number of customers. Each
month, all new customers are put into a drawing. One customer then receives a
$50 credit in a checking account.The amount of money given away in the drawing,

What is the correct function notation to represent the amount of money given
away after the drawing has been going on for 5 months?
G(5) = 250
