There can be other things in the sample beside bacteria that don't grow on this kind of plate like viruses, molds or larger microbes like amoebae. So the sample isn't necessarily sterile.
at a large university a simple random sample of 5 female proffesors is seleted and a simple random sample of 10 male professors is selected. the two samples are combine to give an overall sample of 15 professor. the overall sample is?
only if you are stupid enought to do that and risk jail
It need not be if: the number of samples is small; the elements within each sample, and the samples themselves are not selected independently.
This depends on the nature of solution; when the sample react with an acid the mass decrease and the solution become colored.
It is a program design that allows it to detect permutations of an original sample. This is typically done with anti-virus programs to detect behavior similar to known viruses. This allows an antivirus program with only 30,000 or so definitions to successfully stop over 1,000,000 different viruses.
It keep hearing Stevie Nicks' "Stand Back" sampled in "Alejandro" as well as Hall and Oates' "Out of Touch". Maybe if you combine these with Abba's "Fernando" you get "Alejandro"?
Two Na plus ions will combine with an O2- to form the basic compound sodium oxide. When water is further added, the neutral salt, sodium hydroxide is formed.
Yes, it can be (provided that all the countries where still there ia sporadic cases of polio gets under the program of the WHO, eradication of polio-worldwide and co-operate with them and the laboratories destroys their sample viruses
The weighted arithmetic mean is used, if one wants to combine average values from samples of the same population with different sample sizes: : The weights wi represent the bounds of the partial sample. In other applications they represent a measure for the reliability of the influence upon the mean by respective values. rhinostar
random sample is a big sample and convenience sample is small sample
Authentication is based upon either:Something you know (such as a PIN).Something you have (such as an ID card).Something you are (such as a fingerprint, retina scan or DNA sample).Preferably, authentication will combine two or more of the three.
