okay 1 student = 1/20 chance of picking yellow

1/20 (30/30) = 30/600 chance of picking yellow out of 30 studnets

30/600 = 0.05 = 5% chance of choosing yellow.

I each studnet picks 1 yellow marker. Is that all the options?

Liula [17]

Answer:

1297.37 feet.

Step-by-step explanation:

Given:

The carousel at a local theme park has a diameter of 32 feet.

Each ride last three minutes and the speed of the carousel is 4.3 revolutions per minute.

Question asked:

What is the maximum distance riders travel in one full ride? Round to the nearest hundredth.

Solution:

First of all we will find the radius of the carousel:-

Diameter = 32 feet

Radius, r = $\frac{Diameter}{2} =\frac{32}{2} =16\ feet$

Now, we will find distance covered by the carousel in one ride that means its circumference;

$Circumference\ of \ the \ circle=2\pi r$

$=2\times\frac{22}{7} \times16\\ \\ =\frac{704}{7} \\ \\ =100.571\ feet$

In 1 minute, number of revolution taken by carousel = 4.3

As each ride last for 3 minutes:-

In 3 minutes, number of revolution taken by carousel = 3 $\times$ 4.3 = 12.9

In 1 revolution, distance covered by carousel = 100.571 feet

In 12.9 revolution, distance covered by carousel = 100.571 $\times$ 12.9

= 1297.365 feet

Thus, the maximum distance riders travel in one full ride is 1297.37 feet.

$y > mx+b$

The line is dotted and the shading is above the line

case 3) if you have

$y \geq mx+b$

The line is solid and the shading is above the line

case 4) if you have

$y \leq mx+b$
