Experimental probability = number of positive results / number of experiments
Experimental probability = 67 / 450

Answer:
(2) 72°
Step-by-step explanation:
In this geometry, the angle at the tangent is half the measure of the intercepted arc.
∠CBD = (arc BD)/2 = 144°/2
∠CBD = 72°
__
<em>Additional comment</em>
Consider a point X anywhere on long arc BD. The inscribed angle at X will have half the measure of short arc BD, so will be 144°/2 = 72°. This is true regardless of the position of X on long arc BD. Now, consider that X might be arbitrarily close to point B. The angle at X is still 72°.
As X approaches B, the chord XB approaches a tangent to the circle at B. Effectively, this tangent geometry is a limiting case of inscribed angle geometry.
First, let's figure out how many cups of cheese we need for one dozen people.
There are 12 people in one dozen.
<u>3 cups of cheese </u> = <u>x cups of cheese</u>
6 people 12 people
<u>
</u>
that means we will need 6 cups of cheese for 12 people, or one dozen.
However, we want to make nachos for two dozen people.
6 cups of cheese for one dozen x 2 dozen = 12 cups of cheese
<em>You need 12 cups of cheese to make nachos for two dozen people. </em>

Answer:
6
Step-by-step explanation:
On the fourth day, there were b^3 beads and 216 beads on the belt, which means b^3 = 216. Taking the cube root of both sides, we have b = 6, which means there were 6 beads on the belt on the first day.
