What criteria must a polygon meet to be considered inscribed in a circle? <br> Help ASAP!!

Monica [59]

A polygon is inscribed in a circle if all its vertices are points on the circle and all sides are included within the circle. All regular polygons can be inscribed in a circle. The center of an inscribed polygon is also the center of the circumscribed circle.

The average home price in Massachusetts is $410,000, with a standard deviation of $65,000. A city planner is studying the distri

Answer:

$P(z$

And replacing the value obtained we got:

$z=-1.282$

And if we solve for a we got

$a=410000 -1.282*\frac{65000}{\sqrt{200}}=404107.68$

Step-by-step explanation:

Let X the random variable that represent the average home prices of a population, and for this case we know the distribution for X is given by:

Where $\mu=410000$ and $\sigma=65000$

For this part we want to find a value a, such that we satisfy this condition:

$P(X>a)=0.90$ (a)

$P(X$ (b)

We want to find a value who accumulate 0.10 of the area on the left and 0.90 of the area on the right of the normal standard distributon and for this case it's z=-1.282

And using the distribution for the sample mean we can do this:

$P(X$
