Why is the bandwidth of DPCM is greater than PCM?
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..
When can you estimate a population's size when counting individuals in a sample of the population?
You can estimate a population's size when counting individuals if the density in a sample is greater than the population density.
What is a sample correlation?
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.
A sample mean is the best point estimate of the?
he population mean
Why is it so important to have a representative sample?
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.
Which air sample contains the most carbon dioxide?
the leg
The half life of Carbon 14 is 5470 years If a particular archaeological sample has three quarters of its original radioactivity remaining what is the best estimate for its age?
it is 2860
A sample of ascorbic acid contains 1.50 of carbon and 2.00 of oxygen while another sample of ascorbic acid contains 6.35 of c. How many grams of oxygen does it contain?
23
What is the half life of carbon-14 and what does this refer to?
The half-life of carbon-14 is approximately 5,730 years. This refers to the time it takes for half of the radioactive carbon-14 atoms in a sample to decay into stable nitrogen-14 atoms. This is used in radiocarbon dating to determine the age of organic materials.
How do you calculate age using carbon dating?
Carbon dating measures the amount of carbon-14 remaining in an object to determine its age. By comparing the amount of carbon-14 to carbon-12 in a sample, scientists can calculate the approximate age of the object. The half-life of carbon-14 is about 5,730 years, so by measuring the proportion of carbon-14 remaining, scientists can estimate the age of the sample.
Who measures the ratio of unstable to stable atoms in a rock sample to estimate the age of the fossil it contains?
A geologist or archaeologist would use radiometric dating techniques to measure the ratio of unstable to stable atoms in a rock sample to estimate the age of the fossil it contains. This process involves analyzing the decay of radioactive isotopes present in the rock to determine its age.
Carbon 14 has a half life of 5715 years it is used to determine the age of ancient objects if a sample today contains 0.060mg of carbon 14 how much carbon 14 must have been present in 430 years ago?
.06798mg
When A carbon-14 sample starts with 100 atoms and 5730 years later there are 50 atoms. What is the half-life of carbon-14?
The half-life of carbon-14 is 5 730 years.
In very sample of carbon monoxide the mass ratio of carbon to oxygen is 34?
in every sample of carbon monoxide ,the mass ratio of carbon to oxygen is 3:4
According to Dalton how do the atoms from one sample of the element carbon compare to the atoms of another sample of carbon?
They are identical.
How many moles are there in a 63.60 g sample of carbon?
A 63,60 g sample of carbon is equal to 5,296 moles.
Which element is used for archaeological discoveries?
Carbon-14 dating is commonly used in archaeology to determine the age of organic materials, such as bone and charcoal. This method measures the radioactive decay of carbon-14 isotopes in the sample to estimate its age.
