Answer:
C) Uniform distribution
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely. In this case, the probability of producing a defective light bulb from a production line is the same over an interval of 90 minutes, so the correct answer is C.
We can calculate the probability.
Uniform probability distribution
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 lower than x is given by the following formula.
For this problem, we have that:
Uniformily distributed over a 90 minute interval, that is, between 0 and 90, so and .
We want to find
To find the price per shirt, simply divide the total (combined) cost of the shirts by the amount of shirts
A.) $26.96 (cost of 6 shirts) ÷ 6 (shirts) = $4.49 per shirt
B.) $21.00 (cost of 5 shirts) ÷ (5 shirts) = $4.20 per shirt
C.) $28.50 (cost of 7 shirts) ÷ (7 shirts) = $4.07 per shirt
Comparing A, B, and C, the best buy would be C ($28.50 for 7 shirts)

Answer:
$56
Step-by-step explanation:
$480 times .30 is 144 so you would subtract that from $480 because 144 is 30% of $480.
480-144=336
So then you would subtract 280 from 336 which would be $56.
336-280=56
