The waiting time at which 10 percent of the people would continue to hold is given as 2.3
<h3>How to solve for the waiting time</h3>
We have to solve for X ~ Exponential(λ).
then E(X) = 1/λ = 3,
= 0.3333
Remember that the cumulative distribution function of X is F(x) = 1 - e^(-λx). ; x is equal to the time in over case
For 10 percent of the people we would have a probability of
10/100 = 0.1
we are to find
P(X ≤ t)
= 1 - e^(0.3333)(t) = 0.1
Our concern is the value of t
Then we take the like terms
1-0.1 = e^(0.3333)(t)
1/0.9 = e^(0.3333)(t)
t = 3 * ln(1/0.9)
= 0.3157
Answer:
enduring;
situational
Explanation:
The concept of enduring participation implies the existence of a long-term relationship, regardless of the current situation.
Situational participation depends on the moment and how attractive the event is in a specific period of time.
Answer:
Return on investment ≈ 29%
Explanation:
<em><u>using excel function </u></em>
Determine :
Rate = 7% / 12 = 0.0058
Nper value = 30 years * 12 = 360
PV = -$150,000
∴ PMT value = $997.95
next : calculate the outstanding balance 15 years later
= ( 997.95 / 0.00583 ) * ( 1 - ( 1 / ( 1 + 0.00583 )^15*12 ))
= 171174.96 * 0.6489
= $ 111,075.43
<u>Considering the opportunity to refinance </u>
Rate = 6% /12 = 0.005
Nper = 15 * 12 = 180
Pv = - $111,075.43
∴ PMT = 937.32
the monthly saved up payment = PMT 1 - PMT 2
= 997.95 - 937.32 = $60.63
Finally
Rate of return on investment
= 2500 = 60.63 * 
hence Rate of return ≈ 29 %
attached below is a screenshot of the excel function used for question 2 and it can be used for question 1 as well just change the values
The manager such as the CEO
12 I think is the answer it has jus been answered in my test
