The arithmetic mean is a weighted mean where each observation is given the same weight.
What does mean mean
the mean is an average of a set of numbers
1.The Geometric mean is less then the arithmetic mean. GEOMETRIC MEAN < ARITHMETIC MEAN 2.
The mean of the sampling distribution is the population mean.
shapes made of congruet...?
An equilateral triangle
A squat
Cube, eg dice
No but its diagonals intersect each other at 90 degrees
no
According to the symmetric property (and common sense) line segmetn AB is congruet to line segment BA since they are the same segment, just with a different name
Rectangle: A quadrilateral with 4 right angles, diagonals congruent/bisecting, and opposite sides congruent, BUT ADJACENT SIDES ARE NOT CONGRUENT. Rhobus: A quadrilateral with opposite congruent angles, but adjacent angles are Not congruent, perpendicular bisecting diagonals and 4 congruent sides. Square: A quadrilateral that is a rectangle and a square with 4 right angles, diagonals congruet/bisecting that ar perpendicular, and opposites sides congruent.
In general no.For example a triangle with sides 3, 4, 5 is not congruent to one with sides 3, 4, 6; nor one with sides 3, 4, 2, but in both these examples, two sides are the same.For congruent triangles you need three factors, which can be:Three sides (SSS)Two sides and the enclosed angle (SAS)One side and two angles (AAS)A right angle, hypotenuse. and one side (RHS)
you mean what you mean
Mean is the average.
It mean what you don't what does it mean.
