Answer:
Step-by-step explanation:
The number system in most common use today is the Arabic system. It was first developed by the Hindus and was used as early as the 3rd century BC. The introduction of the symbol 0, used to indicate the positional value of digits was very important.
Answer:
All systems have 2 real solutions.
Step-by-step explanation:
there are X and Y unknowns.
Answer:
<em><u>All three choices would occur, and are all correct.</u></em>
Step-by-step explanation:
The y-intercept of the least-squares regression line would decrease.
The standard deviation of the residuals would decrease.
The correlation coefficient (r) would get closer to 1.
glad to help :)
sqrt(1610) = 40.12 = -40.2
sqrt(680) = 36.08 = -36.08
sqrt(410) = 20.25 = -20.25
sqrt(27) = 5.20 = -5.20
is that supposed to be 025 or negative 25?
the way the question is written
the answer is C & D
The Jacobian for this transformation is
with determinant 
, hence the area element becomes
Then the integral becomes
where 
is the unit circle,
so that
Now you could evaluate the integral as-is, but it's really much easier to do if we convert to polar coordinates.
Then
