The probability that a  randomly selected point within the  circle falls in the red shaded area is p=0.75.

Step-by-step explanation:

We have to calculate the probability that a randomly selected point within the circle falls in the red shaded area.

This probability can be calculated as the quotient between the red shaded area, that is a regular pentagon inscribed in the circle, and the area of the circle.

We start by calculating the area of the circle:

Then, we can calculate the area of the pentagon as:

Then, we can calculate the probability p as the quotient between the areas:

6mm^3 or .6cm^3

  36     6

  /   \     /

6     6   6

factor trees are nice.

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
