Both are correct they just chose a different variable to solve for first. they will both get correct answers if they do the rest correctly.
Answer:
Step-by-step explanation:
Let n be a random variable that represents the first Jonathan apple chosen at random that has bitter pit.
a) P(X = n) = q(n-1)p, where q = 1 - p.
From the information given, probability if success, p = 12.6/100 = 0.126
b) for n = 3, the probability value from the geometric probability distribution calculator is
P(n = 3) = 0.096
For n = 5, the probability value from the geometric probability distribution calculator is
P(n = 5) = 0.074
For n = 12, the probability value from the geometric probability distribution calculator is
P(n = 12) = 0.8
c) For n ≥ 5, the probability value from the geometric probability distribution calculator is
P(n ≥ 5) = 0.58
d) the expected number of apples that must be examined to find the first one with bitter pit is the mean.
Mean = 1/p
Mean = 1/0.126 = 7.9
Approximately 8 apples
Answer: $18
Explanation: 6x3
Using P.E.M.D.A.S. ( parentheses exponent multiply divide add subtract ) you would multiply the nine into the parentheses
The function that models Mason's yearly income is 42,500(1 + 0.035)^x.
Mason's income after 5 years would be $48,084.85.
<h3>What would be Mason's income after 5 years?</h3>
The function that models Mason's income is an exponential function that has the form:
p(1 + r)^x
Where:
- r = percentage increase
- x = number of years
- p = present income
42,500(1 + 0.035)^x
Income after 5 years: 42,500(1 + 0.025)^5 = $48,084.85
