Answer:
<h3>20</h3>
Step-by-step explanation:
Standard deviation of the mean is expressed as:
SM = s/√n
s is the standard deviation of all invoices
n is the sample size of the invoiced
Given
s = $200
n = 100
Required
Standard deviation of the mean
Substitute the given parameters into the given equation
SM = 200/√100
SM = 200/10
SM = 20
Hence the standard deviation of xbar is 20
Probabilities are used to determine the chances of events
The probability that a randomly selected person with multiple jobs is a male or married is 0.782
<h3>How to determine the probability</h3>
The given parameters are:
Sample size, n = 655
Male = 381
Married = 299
Male and Married = 168
The number of those that are male or married is calculated as:
Male or Married = Male + Married - Male and Married
So, we have:
Male or Married = 381 + 299 - 168
Evaluate
Male or Married = 512
The probability is then calculated as:
p = 512/655
Evaluate
p = 0.782
Hence, the probability that a randomly selected person with multiple jobs is a male or married is 0.782

They would be 4 more points because it’s less then on their essay but okay yeah
Answer:
Step-by-step explanation:
The time is inversely related to the number of people working so that as the number of people working increases, the time required decreases
t = k p
divide both sides by p
t/p =k
