-2, -5, -8. The pattern shows that the numbers decrease by 3.
Answer:
At 0 hours, there are 100 grams of the substance remaining.
Step-by-step explanation:
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:
Step-by-step explanation:
31 - 4 + 6 = 33
-17 + 22 - 5 = 0
31 - 4 + 6 > -17 + 22 - 5
