Answer:
a. .0125
Step-by-step explanation:
For each part, there are only two possible outcomes. Either it is defective, or it is not. The probability of a part being defective is independent of any other part. This means that the binomial probability distribution is used to solve this question.
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 combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
2% defective parts.
This means that 
A sample of nine parts from the production process is selected.
This means that 
What is the probability that the sample contains exactly two defective parts?
This is P(X = 2).
0.0125 = 1.25% probability that the sample contains exactly two defective parts. The correct answer is given by option a.
Answer:
see below
Step-by-step explanation:
As you can see 5 - 3 = 2, 2 - 3 = -1 and -1 - 3 = -4 so the rule is subtract 3.
Answer:
117.2
Step-by-step explanation:
Rounding a number to the nearest tenth:
A number rounded to the nearest tenth will have one decimal place.
To do this, we look at the second decimal digit.
If it is less than 5, the first decimal digit is kept.
Otherwise, one is added to the first decimal digit.
In this question:
117.22666
The second decimal digit is 2, which means that we keep the first decimal digit which is also 2.
So, the number rounded to the nearest tenth is 117.2.
The first question would be x + (x + 4). This is because Max has $x and Keisha has (x + 4) because she has four MORE THAN Max. I am pretty sure that the second one is A, but I am not positive. The first one is right though. I hope this helps!!!
