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.

Q1. Look at the picture.

Q2. Look at the picture.

Q3.
Put the value of x = 2 to the equation 3x + y = 5:

<em>subtract 6 from both sides</em>

Q4.

Substitute (*) to (**):
<em>use distributive property</em>

<em>add 33 to both sides</em>
<em>divide both sides by 11</em>

Put the value of m to (*):


Q5.
w - width
3w - length
24 in - the sum of length and width
The equation:

<em>divide both sides by 4</em>
