Answer:
$6520
Step-by-step explanation:
salary = hourly rate * hours + 5% of sales
salary = $13/hour * 40 hours + 0.05 * $120,000
salary = $520 + $6000

Answer:
I'm very sorry. What is the question?
Step-by-step explanation:
Answer:
$21.62
Step-by-step explanation:
Suppose the student guesses the answers, we shall consider this a binomial probability problem of success. This implies that getting a question right is p=1/5.
The number of questions is n=20 questions.
The mean of binomial distribution is
mean=n*p= 20*1/5=4
b] The standard deviation of a binomial distribution is given by:
σ=√(n*p*(1-p))
=√(20*0.2*0.8)
=1.79~1.8
Answer:
μ=4 ; σ=1.8
