Answer:
The correlation coefficient is r = 0.52
Step-by-step explanation:
From the question we are told that
The correlation coefficient is r = 0.52
Generally correlation has no unit and is not affected by unit (i.e it show the ratio between two quantities )
Hence a change of the unit of measurement of length from cm to mm will not affect the correlation coefficient r hence the value will still remain r = 0.52
Answer:
6.5<<em>3rd</em> side <19.9
Step-by-step explanation:
Extremely easy. All you have to do to get the first answer is minus 13.2-6.7 which is 6.5. Then add 13.2+6.7 to get 19.9 for the other answer. So the two answers would be 6.5 and 19.9.

Answer:
11y²
Step-by-step explanation:
16y² + -5y²
So in this expression ignore y² and solve 16 + -5
Since both terms are like terms you can add
16 + -5
= 11
____________________________________________________________
Now add y² to your answer
= 11y²
8pi
C=2pir
We’re given that the radius (r) is 4
So replace r with 4
C=2(pi)(4)
C=8pi
