8am : -14F
noon : -14+10 = -4F
increase between noon and 4 is 2*10 =20
4 pm: -4F + 20 = 16F
temperature at 4 pm is 16F
Answer:
Relationship is linear as r is closest to 1.
Step-by-step explanation:
From statistics we know that,
![\text{Corelation Coefficient}=r=\dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2-(\sum x)^2][n\sum y^2-(\sum y)^2]]}}](https://tex.z-dn.net/?f=%5Ctext%7BCorelation%20Coefficient%7D%3Dr%3D%5Cdfrac%7Bn%28%5Csum%20xy%29-%28%5Csum%20x%29%28%5Csum%20y%29%7D%7B%5Csqrt%7B%5Bn%5Csum%20x%5E2-%28%5Csum%20x%29%5E2%5D%5Bn%5Csum%20y%5E2-%28%5Csum%20y%29%5E2%5D%5D%7D%7D)
Putting all the values from the table,
we get corelation factor as 0.9995
Therefore, the relationship is linear as r is closest to 1.
Answer:
-1
Step-by-step explanation:
the additive inverse of -5is5 because (-5+5=0) &
the multiplicative inverse of -5is 1/-5. because (-5*1/-5=1)
therefore 5*1/-5=5/1*1/-5
=5/-5
=-1
