Step-by-step explanation:
This is the exact form
 
        
             
        
        
        
1. The problem gives the residual value in percentage, and you need it in dollars. So, if the MSRP for the car Jennifer is leasing is $ 17,500, you have:
 57%/100=0.57
 residual value=$17,500*0.57= $9,975
 2. Then, you need to substract the residual value and the lease term, to calculate the value of the car, as below:
 car value=$17,500-$9,975=$7,525 
 3. You need to calculate the money factor, which is the interest rate divided by 2400. Then, you have:
 Interest rate=9%/100=0.09
 Money factor=0.09x2400
 Money factor=0.00375
 4. The interest is:
 I=($17,500+$9,975)(0.00375)
 I=$103.03
 5. Therefore, the monthly payment is:
 Monthly payment=(car value/36 months)+Interest
 Monthly payment=($7,525/36)+$103.03
 Monthly payment=$209.02+$103.03
 Monthly payment=$312.06
 What will Jennifer’s monthly lease payment be?
 The answer is: d. $312.06
        
                    
             
        
        
        
Answer:
Probability (Both fail)  = 0.001369
Probability (None fails) =0.927369
Probability (at least one fails)   = 0.072631
Step-by-step explanation:
given data 
Probability (fail) P = 0.037
two alternators is  independent
solution
we get here first  probability that both will fail will be 
Probability (Both fail) = 0.045²    ................1
Probability (Both fail)  = 0.001369
and 
now we get probability that neither will fail 
Probability (None fails) = (1-0.037)²              ...............2
Probability (None fails) =0.927369
and 
now we get probability that at least one fails 
Probability (at least one fails)  = 1 - Probability (non fails)     .................3
Probability (at least one fails)   = 1 - 0.927369
Probability (at least one fails)   = 0.072631
