This is a mathematical symbol meaning "does not equal", as opposed to the usual "equals" sign.
1. If you do work on an object in one-third the usual time, your power output is A) one third the usual power output. B) the usual power output. C) three times the usual power output. D) impossible to predict without additional information. Answer: C
Standard error (statistics)From Wikipedia, the free encyclopediaFor a value that is sampled with an unbiased normally distributed error, the above depicts the proportion of samples that would fall between 0, 1, 2, and 3 standard deviations above and below the actual value.The standard error is a method of measurement or estimation of the standard deviation of the sampling distribution associated with the estimation method.[1] The term may also be used to refer to an estimate of that standard deviation, derived from a particular sample used to compute the estimate.For example, the sample mean is the usual estimator of a population mean. However, different samples drawn from that same population would in general have different values of the sample mean. The standard error of the mean (i.e., of using the sample mean as a method of estimating the population mean) is the standard deviation of those sample means over all possible samples (of a given size) drawn from the population. Secondly, the standard error of the mean can refer to an estimate of that standard deviation, computed from the sample of data being analyzed at the time.A way for remembering the term standard error is that, as long as the estimator is unbiased, the standard deviation of the error (the difference between the estimate and the true value) is the same as the standard deviation of the estimates themselves; this is true since the standard deviation of the difference between the random variable and its expected value is equal to the standard deviation of a random variable itself.In practical applications, the true value of the standard deviation (of the error) is usually unknown. As a result, the term standard error is often used to refer to an estimate of this unknown quantity. In such cases it is important to be clear about what has been done and to attempt to take proper account of the fact that the standard error is only an estimate. Unfortunately, this is not often possible and it may then be better to use an approach that avoids using a standard error, for example by using maximum likelihood or a more formal approach to deriving confidence intervals. One well-known case where a proper allowance can be made arises where Student's t-distribution is used to provide a confidence interval for an estimated mean or difference of means. In other cases, the standard error may usefully be used to provide an indication of the size of the uncertainty, but its formal or semi-formal use to provide confidence intervals or tests should be avoided unless the sample size is at least moderately large. Here "large enough" would depend on the particular quantities being analyzed (see power).In regression analysis, the term "standard error" is also used in the phrase standard error of the regression to mean the ordinary least squares estimate of the standard deviation of the underlying errors.[2][3]

The usual cause is when air is holding the maximum amount of water possible.
The investment plan that banks offer usually has a minimum and maximum age which ranges between 18-70 years. However, you should check for the exact age from your bank.
The maximum weight capacity of a usual pallet truck scale is around 4,400Lb. This amount can increase and decrease when purchasing better and more expensive pallet trucks.
Minimum temperatures can drop down to 5 degrees but around 10-12 degrees Celsius is more usual. Maximum daytime temperatures generally range between 18 and 24 degrees Celsius.
The electrons on the outermost level are called Valence electrons. the usual maximum is 8.
The common use of dialect often connotes regional identity, cultural heritage, and social belonging. Dialects can signal a sense of community and belonging among speakers who share a particular linguistic variation. At the same time, they can also be stigmatized or seen as less prestigious in some contexts.
Technically no, the absolute minimum working age is 14 and the usual starting age is 16.
