Which of the following represents a function?
2 answers:
Answer: A
Step-by-step explanation:
- a function is the relation between the independent variable (x) and the dependent variable (y)
- the defining characteristics which differentiates a function from a relation is its input and output values
- a function can only have single input value that corresponds to a single output value, or an x value can only lead to one possible y value
- <u>Option A Coordinates</u>
<u />
- each x value only leads to one possible y value
- therefore, option A is a function

Answer:
0.3968 = 39.68% probability this shipment passes inspection.
Step-by-step explanation:
The parts are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x successes is given by the following formula:
In which:
x is the number of successes.
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:
50 parts means that
4 defective means that
10 are chosen, which means that
What is the probability this shipment passes inspection?
Probability that none is defective, so:
0.3968 = 39.68% probability this shipment passes inspection.
