Step-by-step explanation:
For each bulb, there are only two possible outcomes. Either they are defective, or they are not. This means that we solve this problem using the binomial probability distribution.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinatios of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
There are 100 bulbs, so .
3% are defective, so .
a) 0
b) 1
c) 2
d) 3
e) 4
e) 5
Brand A is. Just divide 100 (100% of a pickle) by each number, so 100 divided by 240 and 100 by 325. Then you multiply them by the fraction of 100, which 1/3 is 33.3% and 1/2 is 50%. It comes very close but A is the lowest.
Is 6/2(2+1) 1 or 9? I will tell you why it should be one:
6/2a = 3/a. Let a = 2+1.
A) let the number of cameras sold per day for breakeven be x
Total daily cost = 2000 + 9x
Total daily revenue = 17x
therefore for just covering expenses both cost and revenue must be equal
2000 + 9x = 17x
2000 = 17x - 9x = 8x
x = 2000/8 = 250 cameras
b) increasing production by 50 cameras per day will give a daily profit of;
50 * (17 - 9) = 50 * 8 = $400 (seeing that the fixed daily cost of $2000 remains unchanged)
It's a
