Mileage tests were conducted on a randomly selected sample of 100 newly developed 5) automobile tires. The sample mean tread wear was 50,000 miles, with a population standard deviation of 3,500 miles. What is the best estimate of the average tread life in miles for the entire population of these tires?

On a coordinate grid, point p is at (4, 3) and point r is at (−2, −5). points q and s are a reflection of both points across the x-axis. what are the coordinates of q and s? q(−4, 3), s(2, −5) q(4, −3), s(−2, 5) q(−4, −3), s(2, 5) q(−4, 3), s(−2, 5) ; -; i can't figure it out, if someone can me with the answer,that would be nice
