Answer:

dy/dx = 2x+1/x(x+1)

Step-by-step explanation:

y = In x(x+1)

Let u = x(x+1) = x^2 + x

du/dx = 2x + 1

y = In u

dy/du = 1/u

dy/dx = dy/du × du/dx = 1/u × 2x+1 = 2x+1/u = 2x+1/x(x+1)

The length of human pregnancies from conception to birth varies according to a distribution that is approximately Normal with me

andrey2020 [161]

Answer:

0.5466

Step-by-step explanation:

Given that the length of human pregnancies from conception to birth varies according to a distribution that is approximately Normal with mean 266 days and standard deviation 16 days.

Let X be the length of pregnancies

X is N(266,16)

To find out the probability that pregnancies last between 240 and 270 days (roughly between 8 months and 9 months)

P(240<x<270)

convert each into Z score as $z=\frac{x-266}{16}$

x=240 means Z = -1.625

x=270 means z=0.25

Required prob

= $P(-1.625$
