Answer:
Step-by-step explanation:
The scientific method is the construction and testing of a scientific hypothesis and scientific inquiry is different ways in which scientist study the natural world. They propose explanations based on evidence from their work.
Hope this helps
Answer:
180=144+3X
X=12
Step-by-step explanation:
angles must add to 180
180=45+80+3X+19
gather like terms
180=144+3X
subtract
36=3X
divide
X=12
The sample mean is equal to the population mean.

The standard deviation of X-bar (the standard error) is:
If P has Cartesian coordinates (7, pi/3), then its Polar coordinates are (square root of ((7)^2 + (pi/3)^2) , arcton (pi/21))
<u>Explanation</u>:
The given coordinates (
7
, π
/3
) look as if they are already in polar form (radius = 7
, and angle = π/3).
but in case (
7
, π
/3
) really are Cartesian coordinates (i.e. (
x
,
y
) =
(
7
, π/3
)
)
The radius is given by √(
x /2 + y/
2) and the angle by the arctan (
y
,x
).
