Based on the data, the most likely correlation coefficient would be -1.
The slope between 20 and 30 days is -1, and it represents the change in the surface area of the lake per day.
The data represents correlation, not causation.
Since the data would form a perfectly straight line through the points, the correlation coefficient would be -1 for a perfect decreasing fit.
To find the slope, find the change in the surface area between those days, the change in the days, and write it as surface area/days: 80-90=-10; 30-20=10; -10/10=-1
This is not causation because there could be lurking variables we cannot see.

Answer:
218
Step-by-step explanation:
456 - 238 =
Borrow 1 from 5 so number is 4 4 16 - 238=
16-8 = 8 in ones' place
4 - 3 = 1 in tens' place
4 - 2 = 2 in hundreds' place
2.8 mi
3.3mi
4.8+7(3)=8+21=29mi
5.yes, she hikes continuously so distance can be fractional parts of a mile
7.y=12x+120, y=12(5)+120=180
8.y=6.5x+10,6.5(10)+10=75
The answer is b=8!! hope this help
