How does the experimental probability of choosing a Queen compare with the theoretical probability of choosing a Queen?

The experimental probability is 4 less than the theoretical probability.

The experimental probability is StartFraction 1 over 15 EndFraction less than the theoretical probability.

The experimental probability is StartFraction 1 over 15 EndFraction more than the theoretical probability.

Solve for x. Show or explain your work.
belka [17]

Answer:

-8 = x

Step-by-step explanation:

-15 = 2x + 1

-1            - 1            Subtract 1 from both sides

-16 = 2x                 Divide both sides by 2

-8 = x

To make sure this answer is correct, plug it into the equation to see if it works.

-15 = 2(-8) + 1       Multiply

-15 = -16 + 1          Add

-15 = -15

Norm must pay to have trash collected he can put out 1 barrel of trash per week a rectangler container measure 32 inches by 18 i
Ainat [17]

Answer:

The Cycling Rick container can hold more trash.

Step-by-step explanation:

The rectangular container is basically a rectangular prism, so to find its volume, we are using the formula for the volume of a rectangular prism:

V=whl

where

V is the volume

w is the width

h is the height

l is the length

We know that the rectangular container is 32 inches by 18 inches by 10 inches, so l=32in, w=18in, and h=10in. Let's replace the values in our formula:

V=whl

V=(18in)(10in)(32in)

V=5760in^3

The rectangular container can hold 5760 cubic inches of trash.

Now, the Cycling Rick container is basically a cylinder, so to find its volume, we are suing the formula for the volume of a cylinder:

V=\pi r^2h

where

V is the volume

r is the radius

h is the height

We know that the its height is 30 inches, so h=30in. Since the container is 20 inches wide, its diameter is 20 inches, and since the radius is half the diameter, r=\frac{20in}{2} =10in. Let's replace the values:

V=\pi r^2h

V=\pi (10in)^2(30in)

V=9424.78in^3

The Cycling Rick container can hold 9424.78 cubic inches of trash.

Since 9424.78 cubic inches is bigger than 5760 cubic inches, we can conclude that the Cycling Rick container can hold more trash.
