Answer from: tshepi5348

The correct answer is b. $1920(in)^{2}$

Step-by-step explanation:

We know that the stop sign is in the shape of a regular octagon. Also, a regular octagon can be created using eight triangles of equal area.

We have the dimensions of one of this triangles. One triangle has a base of 20 inches and a height of 24 inches.

Wherever we have a triangle of base '''' and height '''' we can calculate its area using the following equation :

$area=\frac{(b).(h)}{2}$ (I)

The area of one of this triangles using the equation (I) is :

$area=\frac{(20in).(24in)}{2}=240(in)^{2}$

To obtain the area of the stop sign we need to multiply the area of one single triangle by 8 (because a regular octagon can be created using eight triangles of equal area) ⇒

$area_{StopSign}=8.(240in^{2})=1920(in)^{2}$

We found out that the correct answer is b. $1920(in)^{2}$

Answer from: Quest

amount of oatypop that contains the prize = 40%

amount of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

= s +f s +f f s+ff f s+ff f f s+ infinity.where f= failure,s= success

= or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

= = 87.04 %
