Have a nice day.
First of all, let's find the water tank total amount
according to the exercice, there were 2 L (L =liters) of water at 6 am (6hours after midnight ).
Consider T as total amount of water
so we have
T=(6×2)+2=14 as we already know it's emptying 2 L per hour
y=14-2x , here is the equation !
Answer:
The best estimate of the correlation coefficient is 0.9 from the given data.
Step-by-step explanation:
From the scatter plot, the line of best fit will have a positive slope.
So, the correlation coefficient ,
is greater than 0.
so,
≠ - 0.9
Also, there is a deviation from absolute linearity.
So,
≠ 1
Again from the scatter plot it is closer to linearity than further.
Hence,
≠ 0.3 .
So
= 0.9
