The D. O.T. collected data for a particular stretch of I-85 and found that the average speed was 70 mph with a standard deviation of 15 mph and the distribution is approximately normally distributed. The actual Speed Limit for the stretch of road is a maximum of 70 mph and minimum of 40 mph. What percentage of drivers actually drive between 40mph and 70 mph

List the sides of δrst in ascending order (shortest to longest) if: m∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
