Want this question answered?
in pcm entie sample is sent.. where as in dpcm the difference between the predicted value and the original sample is sent which will be smaller when compared rto the original sample..
You can estimate a population's size when counting individuals if the density in a sample is greater than the population density.
If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.
he population mean
If the sample is not representative of the population, then the characteristics of the sample are not the characteristics of the population. Example: If I want to estimate the percentage of the population that are men, and my sample is the school's football team, my estimate would be that 100% of the population is comprised of men. What went wrong with my survey ? Simple. The football team is not a representative sample of the population, at least not as regards gender.

Silicon dioxide contains only silicon and oxygen - no carbon., The only carbon in a sample labelled " silicon dioxide", would be an impurity or contaminant probably on the surface
The half-life of carbon-14 is about 5700 years. Some sources say 5730, but I don't know the accuracy of that number. In the case of carbon-14, this is the period of time for half the original material to decay to nitrogen-14. This is useful in carbon dating, where the ratio of carbon-14 to carbon-12 and carbon-13 is measured, giving an estimate for the age of a carboniferous (plant material) sample.
No, steel is a combination of Carbon and Iron. When referring to steel as "carbon steel" usually means the particular sample contains more carbon. This makes the steel harder but less flexible making it more liable to fracture.

in every sample of carbon monoxide ,the mass ratio of carbon to oxygen is 3:4
The half-life of carbon-14 is 5 730 years.
They are identical.
