AfilCa [17]

Answer:

Therefore the required probability is 0.15.

Step-by-step explanation:

Poisson distribution:

The Poisson distribution is the number of an event is occur within a time period.

P(X=x)=\frac{e^{-\mu}\mu^x}{x!}

μ= The mean

x= event.

In Poisson distribution , the average rate event per time period is constant.

12%  defective parts is produced by one of the machines of the time.

μ= (12%×7)= 0.84

x= the number of defective product =2

P(X=2)=\frac{e^{-0.84}(0.84)^2}{2!}

               =0.15

Therefore the required probability is 0.15.

An old bone contains 80% of its original carbon-14. Use the half-life model to find the age of the bone. Find an equation equiva
Ira Lisetskai [31]

Answer:

An old bone contains 80% of its original carbon-14 in 1844.6479 years

Step-by-step explanation:

We know that

half life time of C-14 is 5730 years

so, h=5730

now, we can use formula

P(t)=P_0(\frac{1}{2})^{\frac{t}{h} }

we can plug back h

and we get

P(t)=P_0(\frac{1}{2})^{\frac{t}{5730} }

An old bone contains 80% of its original carbon-14

so,

P(t)=0.80Po

we can plug it and then we solve for t

0.80P_0=P_0(\frac{1}{2})^{\frac{t}{5730} }

0.80=(\frac{1}{2})^{\frac{t}{5730} }

\ln \left(0.8\right)=\ln \left(\left(\frac{1}{2}\right)^{\frac{t}{5730}}\right)

t=-\frac{5730\ln \left(0.8\right)}{\ln \left(2\right)}

t=1844.6479

So,

An old bone contains 80% of its original carbon-14 in 1844.6479 years
