1) A photographer has noticed that a freshly mixed batch of chemicals will develop photographs faster than an old batch of chemicals. The photographer keeps records of the time needed to develop a print and the age of the chemicals:
Age of chemicals (days) 1 4 6 9 12 14
Time to develop (seconds) 35 38 40 44 49 52
a. Use these data to find the regression equation for predicting time as a function of age of the chemicals.
b. Using your regression equation, predict how long it should take to develop a print if the chemicals are 10 days old. (4 points)

A. Issues [1] In addition to damages for one year's notice period, can a trial judge award significant damages for the mere fact of an employee's dismissal, or for the stigma that that dismissal brings? Or for the employer thereafter competing with the ex-employee for the clients, before the ex-employee has got a new job? B.

Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other
hand, Collaborative communication involves a...
