About 10% of the population has a particular genetic mutation. 700 people are randomly selected. Find the standard deviation for
Oduvanchick [21]

Answer: 7.94

Step-by-step explanation:

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

\sigma=\sqrt{np(1-p)}, 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 :-

\sigma=\sqrt{700\times0.1(1-0.1)}\\\\\Rightarrow\sigma=\sqrt{63}\\\\\Rightarrow\sigma=7.9372539331\approx7.94

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

Nila uses the equation c=8h to figure out the total amount c she should charge a customer if she babysits for h hours.
nydimaria [60]

Answer:

c = 10h

Step-by-step explanation:

c = 8h

Where,

c = Total amount she should charge a customer

h = Number of hours

8 = amount charged per hour of babysitting

A. 8 is the constant of proportionality and it means Nila charges $8 per hour of babysitting

B. If she decides to increase the rate she charges customers by $2 per hour, then the new equation she should use to determine how much to charge her customers is:

c = (8 + 2)h

c = 10h
