After ingesting 15 mL of 95% alcohol, the blood alcohol level of a 75 kg adult male rises rapidly to a maximum level then gradually decreases over time. Measurements of the subject's blood alcohol level at time t (in minutes) since the maximum blood alcohol level was observed gave the following results: Time t (in minutes) Blood alcohol level, B (in mg/L) 10 25 60 70 90 150 160 130 70 60 40 20 ) Using least squares regression, determine an equation of the form B=B,ekt that best fits the relationship shown.

a) Using least squares regression, determine an equation of the form B= Be-kt that best fits the
relationship shown. You do not need to graph the data. (Note any transformations you have
applied to your data: x→, y→, round the values that appear in your final equation to three
significant figures, and use the correct variable names...not x and y.)|
b) Using your equation from part a), estimate the time t at which the subject's blood alcohol level will
be 90 mg/L? Round your answer to the nearest minute.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc70dc89a-4830-4387-b3e3-c1245fb11a40%2Fce78f42a-d75a-4d38-b137-d7191c653f77%2F8n112f1j_processed.jpeg&w=3840&q=75)
