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 arc length of the semicircle is 5π units
<h3>Calculating length of an arc</h3>
From the question, we are to calculate the arc length of the semicircle
Arc length of a semicircle = 1/2 the circumference of the circle
∴ Arc length of a semicircle = 1/2 × 2πr
Arc length of a semicircle = πr
Where r is the radius
From the given information,
r = 5
∴ Arc length of the semicircle = 5 × π
Arc length of the semicircle = 5π units
Hence, the arc length of the semicircle is 5π units

Independent variable (IV): something the scientist can change.
Thus, in this case, the IV can be the weight of the person.
The midpoint of a line divides the line into equal segments.
The option that proves PQ = LO is (a)
The given parameters are:
P is the midpoint of LM.
So, we have:
Q is the midpoint of NO.
So, we have:
Distance PQ is calculated as follows:
This gives:
Distance LO is calculated as follows:
So, we have:
Thus:
Hence, the correct option is (a)
