Answer:
B) There is a correlation between start time and amount of tea consumed. There may or may not be causation. Further studies would have to be done to determine this.
Step-by-step explanation:
Correlation in terms of statistics refers to the relationship that exists between two components. The extent to which the two components or data are related to each other is highlighted with correlation. The change in one component brings the same amount of change in the other component. Correlation discloses the way the variables are related.
In the given excerpt, the correlation between start time and amount of tea consumed has been highlighted. This data is required for further research about the cause.
That would be a right triangle.
The differential equation
is considered exact if (where subscripts denote partial derivatives). If it is exact, then its general solution is an implicit function such that and .
We have
and , so the equation is indeed exact.
Now, the solution satisfies
Integrating with respect to , we get
and differentiating with respect to , we get
Then the general solution to the exact equation is
Answer:
<XYZ = 117°
<XYW+ WYZ = 117°
(6x+44)+(-10x+65)= 117°
6x+44-10x+65= 117°
-4x+ 109= 117°
-4x= 117-109
-4x= 8
x= 8/-4
x= -2
<XYW= 6x+44= 6×-2+44= -12+44= 32°
<WYZ= -10x+65 = -10×-2+ 65= 20+65= 85°
