Why did many americans seek a change in the election of 1980
Naya [18.7K]
<span>That is because they were unsatisfied with the way Jimmy Carter was running the country. Not only was economy doing fairly poor, but he also lost a lot of support because of the way he solved the hostage crisis. All of these combined to allow Ronald Reagan to easily win the presidency.</span>

Find exact volume of a sphere with a radius of 10in
Elodia [21]

To find the volume of a sphere, we can apply the following formula:

(4

/3)πr^3

We know the radius is 10, so we can plug that value in.

(4/3) * pi * 10^3

<h3>V = 4188.79020479in^3</h3>

The question says "exact" volume, so I've included all of the digits in the tenths and beyond place, without rounding.

For the lateral area, don't include the base area. For the surface area, you should include it.

Prisha rolls a fair number cube multiple times and records the result of each roll. Her results are shown in the table.
Leona [35]

Answer:

The experimental probability of rolling a 3 is greater than the theoretical probability of rolling a 3

Step-by-step explanation:

* Lets explain the difference between the theoretical probability and

 experimental probability

- Theoretical probability is what we expect to happen

- Experimental probability is what actually happens when we try it out

- Both of them calculated by the same way, the number of possible ways

 an outcome can occur divided by the total

* Lets solve the problem

- The table has two column;

# Number Cube             # Observed Frequency

           1                                           18

           2                                          16

           3                                          24

           4                                          26

           5                                          16

           6                                          20

        Total                                      120

∵ The experimental probability of rolling a 3 = 24/120 = 1/5 = 0.2

∴ The experimental probability of rolling a 3 = 0.2 = 20%

∵ The theoretical probability of rolling a 3 = 1/6

∴ The theoretical probability of rolling a 3 = 0.1666 ≅ 17%

∵ 20% is greater than 17%

∴ The experimental probability of rolling a 3 is greater than the

  theoretical probability of rolling a 3
