Using the table for many repetitions of the experiment of tossing a coin 10 times, what is the mean number of heads in 50 repeti

When there are 1000 repetitions, the mean will be 5.002.

The charts that you have list the number of total heads when you flip the coin 10 times in each trial.

Multiply the total of each by the number number of heads for that category and divide by 1000.

1 x 0
8 x 1
43 x 2
117 x 3
2017 x 4
248 x 5
203 x 6
121 x 7
45 x 8
6 x 9
1 x 10

If you add up those products and divide by 1000, you have 5.002.

Using the law of large numbers, the experiment with 1000 rolls will be the closest to the theoretical amount.

The party was 5 hours. 353.86-200.51=153.35 then you divide that number by 30.67 and you get 5.

What is the volume of a cylinder with a diameter of 12 in. and a height of 7 in.?
Stels [109]

Answer

Find out the  volume of a cylinder .

To prove

Formula

Volume\ of\ cylinder = \pi r^{2}h

Where r is the radius and h is the height.

As given

Diameter of 12 in. and a height of 7 in.

Radius = \frac{Diameter}{2}

Radius = \frac{12}{2}

Radius = 6 in

\pi = 3.14

put all the values in the formula

Volume\ of\ cylinder = 3.14\times 6\times 6\times 7

                                          = 791.28 in³

Therefore the volume of the cylinder is 791 .28 in³ .
