The polynomial is subtracted using the distributive property.
.. (16k^3 -3v^4) -(-9k^3 +6v^4)
.. = 16k^3 -3v^4 +9k^3 -6v^4
.. = (16 +9)k^3 +(-3 -6)v^4
.. = 25k^3 -9v^4
"Invert" means different things in different contexts. Here we suppose it means you simply want the reciprocal of this difference:
.. (16k^3 -3v^4) -(-9k^3 +6v^4)

Answer:
0.1150 = 11.50% probability that the sample does not contain any fibers of polymer B
Step-by-step explanation:
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this question:
Fibers are chosen without replacement, which means that we use the hypergeometric distribution.
92 fibers means that
Sample of 10 means that
No polymeter B which means that
17 fibers of polymeter B which means that
a. What is the probability that the sample does not contain any fibers of polymer B
This is P(X = 0).
0.1150 = 11.50% probability that the sample does not contain any fibers of polymer B
