All manufacturing processes have some variation. For example, when manufacturing batteries for a smart phone, not all batteries will have the exact same usage-hours upon leaving the factory. In other words, one battery might last 8 hours under normal conditions before needing to be charged; while another battery may last 8.2 hours (under the same conditions) before needing to be charged.
The company advertises that the life of a battery is 8 hours. To maintain quality control, they test battery life of a random sample of batteries coming out of production. The sample had a mean usage time of 8 hours and 10 minutes with a standard deviation of 25 minutes.
The manufacturer feels as though they are replacing too many batteries, and wishes to improve their manufacturing process. They wantto adjust the production process so that only 1 in 100 has a charge life that lasts less than the advertised time. What should the mean time of the manufacture batteries be in order to meet this goal(assuming the standard deviation is unchanged)?

20 points 1. your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. 2. taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1 g(x)=2x^2+1
