Does the data in the table represent a direct variation or inverse variation? Write an equation to model the data in the table.
2 answers:
Answer: B: inverse Variation; xy= 20
Step-by-step explanation:
From the given table, it can be seen that when the values of x is increasing then the values of y decreasing .
Therefore, it is clear that there is inverse variation between x and y.
Also, the equation of inverse variation is given by :-
For x=2 and y=10, we have :
Now, the equation of inverse variation with k =20 will be :

Answer:
(A) 0.006593 or 0.6593%
(B) 0.01538 or 1.538%
Step-by-step explanation:
The total number of possibilities to pick 3 parts out of 15 possible parts is given by the following combination:
(A) There are only three possibilities for which the inspector finds exactly one nonconforming part (NCC, CNC, CCN). Therefore, the probability is:
(B) There are three possibilities for which the inspector finds exactly one nonconforming part, three possibilities for two nonconforming parts (NNC, CNN, NCN), and one possibility for all nonconforming parts (NNN). The probability that the inspector finds at least one nonconforming part is:
