Answer:
The standard deviation is a measure of the dispersion of a series of data
Result = x_{average} ± σ
Explanation:
The standard deviation is a measure of the dispersion of a series of data, it is generally used when a series of measurements of some parameters are made and it is desired to take into account the statistical fluctuations of these measurements, its formula is
where N is the number of measurements
This is a measure equivalent to the absolute error in a single measurement.
Therefore, the number of decimal places in a result must not be greater than the standard deviation.
Result = x_{average} ± σ
Answer:
The driving force behind plate tectonics is convection in the mantle. Hot material near the Earth's core rises, and colder mantle rock sinks. ... Geologists refer to the places where segments meet and divide as plate boundaries. They're thought to wrap around the Earth like seams on a baseball.

Answer:
The answer is below
Explanation:
The question is not complete since the liquid density is not given.
Archimedes principle states that a body at rest in a fluid is acted upon by an upward force known as the buoyant force. The buoyant force is equal to the weight of the fluid displaced.
An object floats when it is placed in a liquid only if the density of the object is less than the density of the liquid. Therefore those metals with density less than that of mercury would float while those with density greater than mercury would sink.
According to Newton's gravitational law, the magnitude of the gravitational force is:
In this case, we have:
Therefore, replacing this values and solving for F' in function of F:
