For which object would a geologist use carbon-14 dating to determine age?​
Debora [2.8K]

Answer:

The correct option is the first one. An animal skull

Step-by-step explanation:

The correct option is the first one. An animal skull

The radiocarbon dating, also referred to as carbon -14 dating, is used for the determining of the age of an object containing organic matter based on the properties of the radiocarbon.

The age detection of the ancient objects are very tough,due to no records are available about the objects.

That's why scientists use carbon-14 dating process.

In this picture, the only object that contains organic material is the animal skull, thus it is the only one that can be dated with this method.

About 78% of the US, population claims that they visit the dentist at least once a year. simple random sample of 200 people is s
Blababa [14]

Answer:

D) 0.78, 0.029

Step-by-step explanation:

Central Limit Theorem:

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

About 78% of the US, population claims that they visit the dentist at least once a year.

This means that p = 0.78

Random sample of 200 people:

This means that n = 200

Mean and standard deviation of the sampling distribution:

By the Central Limit Theorem

Mean \mu = 0.78

Standard deviation s = \sqrt{\frac{0.78*0.22}{200}} = 0.029

So the correct answer is given by option D.
