Find Equation With Least Squares
Question
With computer security always a hot-button issue, demand is growing for technology that authenticates and authorizes computer users. The following table gives the authentication software sales (in billions of dollars), including projections, from 1999 through 2004.
Year x 0 1 2 3 4 5
Sales y 2.4 2.9 3.7 4.5 5.2 6.1
(Here, x = 0 represents 1999)
Find an equation of the least-squares line for these data. Please round the coefficients in your equation to three decimal points. Use the result to estimate the sales for 2009, assuming the projection is accurate.
a. y = 0.749x + 2.262; $9.752 billion
b. y = 0.759x + 2.273; $9.863 billion
c. y = 0.759x + 2.273; $9.826 billion
d. y = 0.749x + 2.262; $9.775 billion
Summary
The question belongs to Mathematics and it is about finding an equation of the least squares for the data.

WHAT OUR STUDENTS SAY
I had missed out on the classes on Leadership and Development at school due to ill health and hardly had the time to go back and understand the topic on my own. That is when I decided to take the assistance of online tutoring at HwA to understand the topic in order to write the projects and assignments that were due. The online HRM tutor assigned to me was extremely patient with all my queries and answered every single one of them. The session really helped to get a grip on the topic and write my assignment essay with excellent examples and reference work.

Religion as a subject is quite sensitive and I needed my world religion assignments to be worded and structured in such a manner so that the analysis was objective and did not appear to be biased or insensitive. The assignment writers at TheReliableTutor.com understood my requirement and with their expertise in writing managed to provide the assignments exactly the way I wanted

When I was assigned the case study analysis of integumentary system patient I had no clue as to where to reach out for help. Luckily I bumped into HwA and was astonished to find that they have specific integumentary system related section.

Excel formulas get me confused at the very basic level and to say that I was in deep waters with using Excel Solver in my math assignments would be an understatement. Thanks to the Excel Solver assignment help experts at HwA, I am now much more confident and my grades have improved.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
