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:
80 minutes or 1 hour and 20 minutes
Since Joe can type 60 word per minute, divide 4800 by 60, you will get 80 minutes which is basically 1 hour and 20 minutes.
60%
You divide 3/5 and then you get a decimal 0.6. Then you convert it to a percentage
Sang grew more. and by 17/40 ( I could be wrong)
