The map of a biking trail is drawn on a coordinate grid. the trail starts at p(−2, 1) and goes to q(6, 1). it goes from q to r(6, −3) and then to s(9, −3). what is the total length (in units) of the biking trail? i need this really soon

The parabola opens: y=√x-4 (principal square root) up down right left

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
