There are 11 ways a pair of dice can show a 5. Of those, 2 have a sum of 6.
Your probability is 2/11.
No, that line will not be the correct line of best fit for the data set
Step-by-step explanation:
A positive correlation relationship means that both variables move in the same direction.
This means when one variable increases the other one also increases or one variable decreases as the other one decrease.
If value of r is 0.2-0.39 it is considered to be weak. Values of r 0.6 and above to 1.0 are considered to be strong.
However,these are all arbitrary limits thus context of the results should be considered.

Answer:
7.13
Step-by-step explanation:
The length of an arc in a circle is radius x the angle (Ф).
Mind you angle Ф should be in radian.
In our case we have the arc length & the radius, find the angle (Ф)
Arc Length = Ф x 4 = 10 meters ===> Ф=10/4 =5/2 = 2.5 RADIANS
Now let's convert 2.5 RADIANS into DEGREE:
2.5/π = x/180 ===> x= (2.5 x 180) / π ==>143.239° or 143.24° (A)
