Two companies, A and B, drill wells in a rural area. Company A charges a flat fee of 3681 dollars to drill a well regardless of its depth. Company B charges 1168 dollars plus 10 dollars per foot to drill a well. The depths of wells drilled in this area have a normal distribution with a mean of 260 feet and a standard deviation of 40 feet. Find the probability that Company B would charge more than Company A to drill a well.

Complete the standard form of the equation that represents the quadratic relationship displayed above, where a, b, and c are rational numbers.

Select the margin of error that corresponds to the sample mean that corresponds to each population: a population mean of 25, a standard deviation of 2.5, and margin of error of 5%
