Answer:
The graph I expect to have a negative correlation is the third graph.
Step-by-step explanation:
Positive correlation is when the the x-values increase with a corresponding increase in y-values.
Negative correlation is when the x-values increases with a corresponding decrease in y-values.
No correlation is when only x or y variable changes.
From the graphs given the only one that has a negative correlation is the third graph.
7 stamps. He will give 6 stamps to them each and there will be 7 left
Answer:
1/6 or 2/12
Step-by-step explanation:
Answer:
Should be P(A∩B)=P(A)⋅P(B)
Polar coordinates (r,ϑ) and Cartesian coordinates (x,y) are related as follows:
Cartesian -> Polar
x = r cos(ϑ)
y = r sin(ϑ)
Polar -> Cartesian
r^2 = x^2 + y^2
ϑ = arctan( y/x)
The polar coo's can be extended to cylindrical by introduction a dimension z - which is perpendicular to the polar plane, it follows that:
z = z
in between the systems (r,ϑ,z) and (x,y,z)
The polar coordinates are particularly useful when a problem has circular or cylindrical symmetry, i.e. it is usually "easier" to perform calculations on a circle (for example) using the polar coordinates.
