∙ 15y agoYou can think of an arc as a fraction of the circumferance of a circle. Also, a complete circle is 2pi radians, so any central angle is THETA / 2pi of a complete circle. Multiply by the circumferance to get the length of the arc: THETA / 2pi * 2(pi)(r) = THETA * r or the length of the arc is simply the radius times the central angle in radians

It depends on what measures you are comparing between!
The relation between the arc of length and the central angle is that the arc of length divided by one of the sides is the central angle in radians. If the arc is a full circle, then the central angle is 2pi radians or 360 degrees.
Negative skewness means the average (mean) will be less than the median. Positive skewness means the opposite. I'm not sure if any rule holds for the mode.

Simple Harmonic Motion (SHM) involves an oscillating motion back and forth around a central equilibrium point, while uniform circular motion involves an object moving in a circular path at a constant speed. The two are related in that the projection of uniform circular motion onto one axis can produce SHM, such as the motion of a pendulum. Mathematically, SHM can be described using trigonometric functions that are similar to those used to describe uniform circular motion.
"Measures of central tendency are statistical measures." is an accurate statement.
Measures of central tendency are averages. Range , the difference between the maximum and the minimum, is a measure of dispersion or variation.
One of the measures of central tendency IS the average, also known as mean. You can't calculate the average from other measures of central tendency.
It varies, since the moons orbit around earth is not perfectly circular and central.
"What are the benefits of measures of central tendency? Explain with an example
