Apaleotndologist finds a bone that might be a sauropod’s bone. in the laboratory, she finds that the carbon-14 found in the bone is 1/10 of that found in a living bone tissue. could this bone have belonged to a sauropod? explain your reasoning. (hint: the sauropods lived from 200 million years ago to 145 million years ago. the constant for carbon-14 is 0.00012.)
a.) no, because the amount of carbon-14 found indicates a period before the sauropods even came into existence.
b.) no, because the amount of carbon-14 found indicates a period after the sauropods became extinct.
c.) yes, because the number of years calculated is in the range of 200 million years and 145 million years ago.
d.) yes, because the amount of carbon-14 found in the bone is one-tenth of that found in a living bone tissue.

  b.)  No, because the amount of Carbon-14 found indicates a period after the sauropods became extinct.

Step-by-step explanation:

The amount of time corresponding to the fraction found satisfies the equation ...

  1/10 = e^(-0.00012t)

  ln(1/10) = -0.00012t . . . . . taking natural logs

  t = ln(1/10)/-0.00012 ≈ 19,200 . . . . years

19000 years is much different from 145 million years, so the bone will be much different from a sauropod bone. The bone found is from a time later than the last living sauropod.

probability for j is 1/4

while

a is 1/6

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
