Answer:
sample variance
the value of the one observation
the mean value of all observations
the number of observations
Step-by-step explanation:
Answer:
X = 25°
Step-by-step explanation:
The sum of angles between two parallel lines is 90°.
So, (2x-5) = 90°-45°
= 45°
<u>4</u><u>5</u><u>+</u><u>5</u> = <u>5</u><u>0</u> = 25°

Answer:
C) ( 8,2) and (4,1)
The slope of the line
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the set of points ( 8,2) and (4,1)
ThesSlope of the line
The slope of the line
The volume of any solid whose base is uniform is V = Ah. Since
the base is a sector of a circle, it’s area is defined by the equation A = θ (r^2)/2, where θ is in radians.
90 degrees in radians
is Pi/2. So the A = (PI) (r^2)/4
Therefore, V = [(PI) (r^2)/4]*h
