bThe average rate of change of the linear function f(x)=3x+5 between any two points is ________.
The scatter plot below shows data for the average cost of a high-end computer (y, in dollars) in the year x years since 2000. The least squares regression line is given by yˆ=−1677+314x. A coordinate plane has a horizontal x-axis labeled Year from 4 to 12 in increments of 2 and a vertical y-axis labeled Cost in dollars from 0 to 2000 in increments of 500. The following points are plotted: left-parenthesis 6 comma 250 right-parenthesis, left-parenthesis 7 comma 550 right-parenthesis, left-parenthesis 9 comma 1000 right-parenthesis, left-parenthesis 10 comma 1300 right-parenthesis, and left-parenthesis 11 comma 2000 right-parenthesis. A line rises from left to right, passing through left-parenthesis 7 comma 550 right-parenthesis and left-parenthesis 10 comma 1500 right-parenthesis. All coordinate are approximate. Interpret the y-intercept of the least squares regression line. Select the correct answer below: The predicted cost of a computer in the year 0 is…

Disk drives have been getting larger. Their capacity is now often given in terabytes (TB) where 1 TB = 1000 gigabytes, or about a trillion bytes. A study of external disk drives finds the data available below. The least squares line was found to be Price = 14.00 + 66.457 Capacity with s. = 49.27 and SE (b,) = 13.2769. The assumptions and conditions for regression are met. Complete parts a through c below. E Click the icon to view the external disk drive data. a) Disk drives keep growing in capacity. Some tech experts now talk about the Petabyte (PB = 1000 TB = 1,000,000 GB) drives. What does this model predict that a Petabyte-capacity drive will cost?
