Step-by-step explanation:
Given
--- sample size
-- defective
--- selected
Required
The probability that the batch will be accepted
When the first is selected, the probability that it is okay is:
<em>The subtraction is done to get the number of items that are not defective</em>
Now, there are 2099 left
For the second selection, the probability is:
Now, there are 2098 left
For the third selection, the probability is:
Now, there are 2097 left
For the fourth selection, the probability is:
So, the probability that the batch will be selected is:

Answer:
The distance between of the park to the school is approximately 8.6 miles
Step-by-step explanation:
The given information are;
The location of the school from the house = 4 miles East and 1 mile South
The location of the park from the house = 3 miles East and 4 mile South
By representing the direction East (x-direction) as being in the direction of vector 
and the direction South (negative y-direction) as being in the direction of vector 
, we have;
The location of the school from the house = 4· +
The location of the park from the house = 3· + 4·
The distance, l, between the park and the school is given by the resultant of the two vectors as follows
= 4· + 3·
= + 4·
Therefore,
The distance between of the park to the school ≈ 8.6 miles.
Answer:
Step-by-step explanation:
12nl-4=8 start by adding 4 to both sides.
12nl=12/l Divide both sides by l.
12n=12 then divide both sides by 12.
n=1/l
