Answer:
a) 80% probability that x lies between 7 and 27.
b) 28% probability that x lies between 6 and 13.
c) 44% probability that x lies between 9 and 20.
d) 28% probability that x lies between 11 and 18.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value x between c and d, in which d is larger than c, is given by the following formula.
Uniform distribution from a = 4 to b = 29
(a) Find the probability that x lies between 7 and 27.
So
80% probability that x lies between 7 and 27.
(b) Find the probability that x lies between 6 and 13.
So
28% probability that x lies between 6 and 13.
(c) Find the probability that x lies between 9 and 20.
So
44% probability that x lies between 9 and 20.
(d) Find the probability that x lies between 11 and 18.
So
28% probability that x lies between 11 and 18.
Answer:
The minimum number of bicycles that must be produced and sold to break even = 20
Explanation:The profit generated by producing and selling n bicycles per week is given by the formula:
To get the minimum number of bicycles that must be produced and sold to break even, let P(n) = 0 (Since break even means no profit is made)
Solve the resulting quadratic equation above
This means that, to break even, either 60 or 20 bicycles must be produced and sold
The minimum number of bicycles that must be produced and sold to break even = 20
