What is the x in this equation <br><br> 14x−8=4

Aleksandr-060686 [28]

Answer:

x = 6 / 7

Step-by-step explanation:

Let's solve your equation step-by-step.

14 x − 8 = 4

Step 1: Add 8 to both sides.

14x − 8 + 8 = 4 + 8

14x = 12

Step 2: Divide both sides by 14.

14 x / 14 = 12 / 14

x = 6 / 7

Find the standard deviation, σ, for the binomial distribution which has the stated values of n and p. round your answer to the n

True [87]

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.
