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

Evaluate for x=2 and y=3: x^2y^-3/x^-1y
Artemon [7]

Answer:

8/81

Step-by-step explanation:

It's most efficient to simplify the quotient algebraically before inserting the values of the variables x and y.  

The given expression reduces to x³ / y^4.

Substituting 2 for x and 3 for y, we get:

 (2)³           8

--------- = ---------- (Agrees with first given possible answer)

 (3)^4         81
