A technology firm in Erie, Pennsylvania, receives a contract to develop a
computer program controlling the angle of a solar array on a daily basis.
In order to develop the program, the firm first needs to model the
hours of sunlight for every day of the year. The graphs below show the
amount of hours of daylight for Erie, Pennsylvania, on December 21,
March 21, June 21, and September 21. From December to March, the
hours of daylight are increasing faster and faster, and from March to
June, they are increasing slower and slower. Which graph would be an
appropriate model for this firm to use?
answer in image
,The following graph represents revenue from vending machines at a
large business during a typical day. The y-axis represents revenue in
dollars, and the x-axis represents time. What is the difference between
the maximum revenue and the minimum revenue?
Answer- $85
The U.S. housing price index from 1970 to 2010 is plotted in the graph
below. Which conclusion about this graph is correct?
Answer- The lowest housing price index occurred in 1970, and the
highest housing price index occurred in 2005.
,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?
Answer- 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?
Answer- The average cost reduces to about $2 per cover.
, A software developer recently launched a new social media app and is
concerned about user retention (i.e., users continuing to use the app
after initial download). In order to study the retention of users, the
company looked at users who shared three or more pictures on the app
within the first five days of downloading the app (Group A, which is
indicated by the solid line in the graph below) and compared the use of
the app by these users in the days following the initial download with
the use of the app in the days following the initial download by users
who did not share three or more pictures on the app within the first
five days after downloading the app (Group B, which is indicated by the
dashed line in the graph below). The data in the graph shows the
retention rates for these two groups, where t is the number of days
since the initial download of the app, and y is the percentage of users
who still use the app
The retention rates of both Group A and Group B stabilize as time
increases and appear to have different asymptotes.
