X-8y+5=0
Step by step explanation
Answer:
The answer to
1. 22/5
2. 3
Step-by-step explanation:
Answer:
(3, - 1 )
Step-by-step explanation:
given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( 
, 
)
here (x₁, y₁ ) = R (4, - 5 ) and (x₂, y₂ ) = D (2, 3 )
midpoint = ( 
, 
) = ( 
, 
) = (3, - 1 )
Assuming 8ft is the radius and 12ft is the height, the answer is approximately V=2412m^3
The value of a correlation coefficient ranges between -1 and 1.
The greater the absolute value of the Pearson product-moment correlation coefficient, the stronger the linearrelationship.
The strongest linear relationship is indicated by a correlation coefficient of -1 or 1.
The weakest linear relationship is indicated by a correlation coefficient equal to 0.
A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.
A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.
therefore
d is correct
-0.9
