1) The line plot shows the part of a gallon of water that Jill drank each day last week. How many gallons of water did Jill drink?

3 1/8

Step-by-step explanation:

1. You can add the 2 halves together making 1

2. Then add a 3/4 and one 1/4 together making another 1

3. With the remaining two 1/4s, that makes another half. So at the moment, you have 2 1/2

4. Convert 2 1/2 to eighths. 2 4/8

5. Finally add one 5/8.

So the answer is 3 1/8

a. the residual plot for model 1 has a random pattern and is a good fit for the data.
