1/2 hour = 30 minutes = 1800 seconds = 1/12 day

Deffense [45]

Answer:

5.10 people

Step-by-step explanation:

Calculation to Find the standard deviation for the number of people with the genetic mutation

Using this formula

Standard deviation = √ ( n * p * q)

Where,

n = 400

p = .07

q = 100%-7% = 93% or .93

Let plug in the formula

Standard deviation =√400*07*.93

Standard deviation =√26.04

Standard deviation = 5.10 people

Therefore the standard deviation for the number of people with the genetic mutation is 5.10 people.

The employees that drive to work is 380

The total number of employees that drive to work is 660

<h3>How many employees drive to work?</h3>

A fraction is a non integer that is made up of a numerator and a denominator. A fraction is used to express the ratio or the relationship between two or more quantities. An example of a fraction is 1/2.

The number of employees that drive to work can be determined by multiplying the fraction of the employees that drive to work by the total number of employees.

Employees that drive to work = 2/3 X 570 = 380

In order to determine the employees that drive to work, take the following steps:

Determine the total number of employees : 3 x 330 = 990

The total number of employees that drive to work: 2/3 x 990 = = 660
