About 10% of the population has a particular genetic mutation. 700 people are randomly selected. find the standard deviation for the number of people with the genetic mutation in such groups of 700.

7.94

Step-by-step explanation:

The formula to calculate the standard deviation for binomial distribution :-

, where n is the number total of trials and p is the probability of getting success in each trial.

Given : The probability of the population has a particular genetic mutation=0.1

If 700 people are randomly selected, then the standard deviation for the number of people with the genetic mutation in such groups of 700 will be :-

Hence, the standard deviation for the number of people with the genetic mutation in such groups of 700 = 7.94

the line of reflection is x=3

Step-by-step explanation:

The reflection and original shape are equal distant from x=3 you can use midpoint formula to mathematical determine this.
