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
To be honest, chemical engineering is not my field. However, I had to deal with heat transfer assignments during one of my metallurgy assignments. The experts here are spot on and helped me get good grades without any hassle. The experience had been wonderful to say the least.

I was really nervous about my college application essay for a university in Sydney but luckily I came across HwA and with the help of their wonderful support team, my application essay was highly appraised. Since then I often take help and assistance for my essay writing projects.

I was struggling with the deadlines of my assignments and increasingly felt at a loss with my Asian Legal Studies assignments. 24 hours in a day were not enough to do the research and structure the assignment essay. At TheReliableTutor the tutors understand my deadlines and I have never had them delay.

I was having difficulty in structuring and writing the nuclear chemistry assignment on Balancing Nuclear Equations & Predicting the Product of a Nuclear Reaction. The nuclear chemistry assignment expert guided me through the process in such a way that I not only finished writing the assignment but also acquired a clear concept of the topic.

Honestly speaking, most of the online essay writing experts, available on the internet, are US based writers. So, naturally their perspectives are different than what we are being taught in our school. The variation in socio-political viewpoints makes critical impact in the arguments presented in an essay. Luckily, HwA has essay writing experts who have not only passed out from schools from New Zealand but also taught there. So, naturally they understood the need of the argumentative essay I needed, and delivered quality work.

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
