Using the binomial distribution, it is found that the variance of the number that pass inspection in one day is 5.7.
For each component, there are only two possible outcomes, either it passes inspection, or it does not. The probability of a component passing inspections is independent of any other component, hence, the binomial distribution is used to solve this question.
Binomial probability distribution
Probability of <u>exactly x successes on n repeated trials, with p probability</u>, and has variance given by:

In this problem:
- 95% pass final inspection, hence

- 120 components are inspected in one day, hence
.
The variance is given by:

The variance of the number that pass inspection in one day is 5.7.

To find the answer you would need to add 11 to 75 and then that is 86 so then divide that by 1 and the answer is 86
Answer:
The last one, 8 / 0
Step-by-step explanation:
The last expression is undefined because in math it is forbidden to divide by zero.
Hope this helps)))
20 total marbles....7 are green
probability on first draw is 7/20...and since the marble was not replaced, the probability on the second draw is 6/19. And since they cant happen at the same time, we multiply
7/20 * 6/19 = 42/380 which reduces to 21/190
Answer:
-1 
Step-by-step explanation:
4x-8y=15
4x-8y-4x=15-4x
-8y=15-4x
-8y/-8=15-4x/-8
y=-1 7/8+1/2x
slope is -1 7/8
