$f(x)=-\frac{2}{3}x+5$

f(12) this means that x is 12, so you can plug in 12 for "x" in the function:

$f(x)=-\frac{2}{3}x+5$

$f(12)=-\frac{2}{3}(12)+5$

$f(12)=-\frac{24}{3} +5$

f(12) = -8 + 5

f(12) = -3

Your answer is -3

Y^3-27=9y^2-27y how to factor

Kryger [21]

Hello! And thank you for your question!

First we are going to redo the equation:

y^3−3y^2(3)+3(y)×3^2−3^3=0

Then we are going to use Cube of Difference:

0 = (y - 3)^3

That take cube root of both sides:

0 = y - 3

Finally add 3 to both sides:

3 = y

Final Answer:

y = 3

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 $z=\frac{x-266}{16}$
