UIL-B regression problem

Postby MathMaestro » Mon Feb 22, 2010 6:43 pm

I tried all the regressions on the TI-84 and TI-89, and I tried the log scaling regression x vs log y, but I can't seem to find a quick 30-second technique to solve this. Any gurus have insight on this?

10B-47 Moore's Law predicts that the number of transistors on a circuit board doubles every 2 years. In 1971, the count was 2300. In 1981 it was 100,000; in 1990 it was 1,000,000; in 2008 it was 1.5 billion. Based on these data, what is the actual time for doubling the number of transistors?
