Answer:
for 3644 produced books the costs will be the same.
Step-by-step explanation:
x = number of books
f(x) = production method 1 costs
g(x) = production method 2 costs
f(x) = 11.75x + 57077
g(x) = 21.25x + 22459
for what number of books (x) will that be the same ?
11.75x + 57077 = 21.25x + 22459
34618 = 9.5x
x = 34618 / 9.5 = 3644
Answer:
The probability that the first failure occurs among the five devices is given by
(a) 9 months =
(b) 12 months=
Step-by-step explanation:
probability is given as the; number of required outcome/ total number of possible outcome.
7%=0.7 14.5×.07=1.01500. 1.01500 1.02. 14.50+1.02=$15.52.
60%. You count how many total (15) and then how many got below a 90 (9) and then divide 9 by 15.
