Assume that the mean length of a human pregnancy is 268 days with a standard deviation of 9 days. What percentage of human pregn

Ann [662]

Μ = 268 days, the population mean
σ = 9 days, the population standard deviation

For the random variable x = 272 days, the z-score is
z = (x-μ)/σ
= (272 - 268)/9
= 0.4444

From z-tables, obtain
P(z <= 0.6716) = 0.6716 = 67.2%

Answer: 67.2%

The work done by $\vec F$ is

$\displaystyle\int_C\vec F\cdot\mathrm d\vec r$

where $C$ is the given curve and $\vec r(t)$ is the given parameterization of $C$ . We have

$\mathrm d\vec r=\dfrac{\mathrm d\vec r}{\mathrm dt}\mathrm dt=k(1-2t)\,\vec\imath+\vec\jmath$

Then the work done by $\vec F$ is

$\displaystyle\int_0^1((t-kt(1-t))\,\vec\imath+kt^2(1-t)\,\vec\jmath)\cdot(k(1-2t)\,\vec\imath+\vec\jmath)\,\mathrm dt$

$=\displaystyle\int_0^1((k-k^2)t-(k-3k^2)t^2-(k+2k^2)t^3)\,\mathrm dt=-\frac k{12}$

In order for the work to be 1, we need to have $\boxed{k=-12}$ .
