The statistician performed a linear regression and also plotted the residuals.
• Based on the residual plot, the statistician decided to exclude one data point.
The statistician then performed linear regression on the set of remaining data points.
• The result was that the new linear model fit the remaining data more closely than the original model fit the original de
Which data point did the statistician exclude?

Which expression is equivalent to (9x - 3 1/ + 1 3/8)

Acable company wants to provide cell phone service for residents on an island. the function for the cost of laying the cable from the island to the mainland is c(x)= 6.500 square root x2+4, where x represents the length of the cable in feet. what are the domain and range of the function? a) domain: all real numbers range: all real numbers greater than or equal to 17,000 b) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 17,000 c) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 13,000 d) domain: all real numbers greater than or equal to 13,000 range: all real numbers greater than or equal to 0
