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.
The quadrilateral adds up to 360 degrees.
the 3 angles given add up to 289 degrees.
subtract the 3 given from 360
360 - 289
71 degrees.
i hope this helped!
If you dont mind, please give me the brainliest answer! i am three away from the next rank :D
Answer:
1
Step-by-step explanation:
<em>⇒2/3 ÷ (-4) - [ 1/6 - 8/6]</em>
<em>⇒2/3 / (-4) - [- 7/6]</em>
<em>⇒-1/6 + 7/6</em>
<em>⇒6/6</em>
<em>⇒1</em>
