The graph shows the number of milligrams of a chemical in the body,  days after it was first measured. Explain what the point (1, 2.5) means in this situation. Mark the point that represents the amount of medicine left in the body after 8 hours

A car is initially located 40 km North of a truck. The car then begins to travel North at 20 km/h, while at the same time, the truck travels due West at 30 km/h. After travelling for 2 hours , the distance between the two vehicles is 11. A. decreasing at 26 km/h B. increasing at 26 km/h C. decreasing at 34 km/h D. increasing at 34 km/h

Each row represents an experimental “run” (in this case, averaged sample of mango wine). Column A shows the run number; Column B shows the percentage of ethanol; Column C shows the amount of glycerol (in g/L); Column D shows the amount of acid (in g/L); Column E shows the temperature of the run (in °C); and Column F shows the pH of the run. Y represents Ethanol of mango wine. 1. Create a scatterplot of the ethanol data for all 20 runs  a. Draw a graphical representation of the model that you chose to use. b. Comparing the model to your data, evaluate its fit in one or two sentences. (Not sure what this question is getting at. I've provided all the information given) c. Replace the generic Yi = β0 + ε with the information you have here. Please help. I have no idea what this even means or where to start. HERE is the attached dataset to start with;    a          b             c              d            e           f Run Ethanol Glycerol Acidity Temp pH 1 4.8 3.5 0.84 24 3.8 2 9.6…
