In a destructive test of product quality, a briefcase manufacturer places each of a simple random sample of the day’s production in a viselike device and measures how many pounds it takes to crush the case. from past experience, the standard deviation has been found to be 21.5pounds. for 35 cases randomly selected from today’s production, the average breaking strength was 341.0 pounds. the lower confidence limit of 99% confidence interval for the mean breaking strength of the briefcases produced today would equal to;

Malia is observing the velocity of a cyclist at different times. after two hours, the velocity of the cyclist is 15 km/h. after five hours, the velocity of the cyclist is 12 km/h. part a: write an equation in two variables in the standard form that can be used to describe the velocity of the cyclist at different times. show your work and define the variables used. (5 points) part b: how can you graph the equations obtained in part a for the first 12 hours? (5 points) if you can try and make this as little confusing as you can
