Alkalinity is determined by titration with standard acid. The alkalinity is often expressed as mg/L of CaCO3. If Vp mL of acid of normality N are required to titrate Vs mL of sample to the the phenolphthalein end point, what is the formula for the phenolp Is physical chemistry qualitative...
This requires a single deviation from the right-of-way, at Shell Interlocking just south of New Rochelle, which deviation is calibrated not to damage a historic building close to the track and may not require any building demolitions at all; the main purpose of the Shell Interlocking project i...
is read “n choose x”, and refers to the number of combinations that x outcomes can be picked from n possibilities. It is calculated using the factorial function. As the number of trials (n) gets larger than 70, n factorial gets enormous and can no longer be calculated on a standard ...
1. About 68% of the data lies between one standard deviation of the mean (μ± 1σ). 2. Roughly 95% of data lies within two standard deviations of the mean, μ± 2σ. 3. About 99.7% of the data lies within three standard deviations of the mean (μ± 3σ). This rule is very...
To interpret this indicator, one has to look at the divergences between the share price development and the indicator. If, for example, the share price increases further and the indicator does not follow this movement, this is regarded as a sign that the share price movement is not backed by...
(Actually, from the Brunn-Minkowski inequality, the distribution of these entries is log concave, so once once controls the standard deviation one also gets a bit of exponential decay beyond the standard deviation; Narayanan and Sheffield had also recently established the existence of a rate ...
Money makes the world go round, and in the vast world of finance, there are various ways to earn a profit. One such method is by receiving a finder’s fee. But what exactly is a finder’s fee? How does it work, and what are the standard fees involved? In this blog post, we’ll...
These mechanisms might be at an atomic level, where the cloud of electrons surrounding the nucleus of an atom is displaced, resulting in an atom having a slightly positive charge on one side and corresponding negative charge on the other. It can also occur at a molecular level, due to ...
A calculator is a device that performs mathematical calculations. You input numbers and operations using the buttons, and it quickly calculates and displays the result on the screen. Many calculators use microchips and programming to execute the calculations. ...
This is equivalent to using multiple JOINS in an SQL statement. Specify data types for the lookup column: Up until now, when you configure lookups, the child column inherits the data type of the parent column. With new update, you can now pick a different data type for the child column...
