Answer:
$62.32
Step-by-step explanation:
54.19 · 15/100 = 812.85/100 = 8.1285
simplify 8.1285, so it's 8.13
$54.19 + $8.13 = $62.32

Answer:
P(at least 1 wrong in 10) =0.5160
Step-by-step explanation:
Let A be the event that there is a problem in the proces. Then the probability of problem with the process is P ( A) = 0.07
Let B be the event that the process is without the problem. Then the probability of without problem is P ( B) = 0.93
Now we want to find the 10 successive points of event B. Since the events are independent we can find this as
P(B)+P(B)+P(B)+P(B)+P(B)+P(B)+P(B)+P(B)+P(B)+P(B)
or
P(B)^ 10= .93^10=0.48398
As we have to calculate at least 1 in 10 then we will subtract it from 1.
P(at least 1 wrong in 10) = = 1 - .93^10 =1- 0.48398=0.5160
