1. At what temperature is the electronic device running if its estimated is 120 hours.

2. Estimate the life time of the electronic device in hours it is runing on 53 degrees celcius

3. At what temperature is the electronic device running if its estimated is 240 hours.

17. A company manufactures an electronic device to be
used in a very wide temperature range. The company
knows that increased temperature shortens the life time
of the device, and a study is therefore performed in
which the life time is determined as a function of
temperature. The following data is found:

The following linear regression model can be used to predict ticket sales at a popular water park. Ticket sales per hour = - 631.25 + 11.25(current temperature in °F)23) Choose the statement that best states the meaning of the slope in this context. A) The slope tells us that a one degree increase in temperature is associated with an average increase in ticket sales of 11.25 tickets. B) The slope tells us that high temperatures are causing more people to buy tickets to the water park. C) The slope tells us that if ticket sales are decreasing there must have been a drop in temperature. D) None of these
