The standard deviation is 19.91.

To find the standard deviation is a binomial distribution, you have to take the square root of the total number multiplied by the percent and its compliment.

Our expression will be:

\sqrt{x} 1617*.57*.43

This will evaluate to about 19.91.

(20+80 divided by 2x8) divided [(54 divided by 9+14)divided by 4]
lesya692 [45]

Answer:

80

Step-by-step explanation:

Let's write out the equation:

8(20+80/2)/[(54/9+14)/4]

For the first part we get 8(100/2)

Then 50x8

Then 400

For the second part we have (6+14)/4 as we divide 54 by 9. PEMDAS

Then 20/4

Then 5

So our final answer is 400/5 which is 80.

Hope this helps!
