Which set of ordered pairs does not represent a function?
Irina18 [472]
<h3>Answer:</h3>

B. { (3, –2), (3, –4), (4, –1), (4, –3) }

<h3>Step-by-step explanation:</h3>

Functions are a set of points that show how dependent variables change through independent variables.

Defining a Function

In functions, each x-value is assigned to exactly one y-value. This means that x-values do not repeat. So, if there is one x-value more than once in a set, then it cannot be a function.

For example, set B has the x-value 3 and 4 repeated twice. Thus, it does not represent a function.

Graph of a Function

Functions can also be defined through a graph. Just like with coordinate points, x-values do not repeat on the graph. You can use the vertical line test to see if a graph is a function. If you can draw a vertical line at every point on a graph without it ever intersecting with the graph more than once, then it is a function.

The null hypothesis claims that the proportion of community college students who work full-time is 0. 45. The alternative hypoth
diamong [38]

The stronger the evidence is against the null hypothesis, the higher the divergence from it.

What do you mean by null hypothesis ?

A statistical hypothesis known as a null hypothesis asserts that no statistical significance can be found in a collection of provided observations. Using sample data, hypothesis testing is performed to judge a theory' veracity. It is sometimes referred to as just "the null," and its symbol is H_{0}. To determine if a theory regarding markets, investing methods, or economies is correct or wrong, quantitative analysts employ the null hypothesis,

The null hypothesis states that the percentage of the population who works full time is 0.45.

As a result, 450 persons who are randomly selected from a population of 1000 work full-time.

A different hypothesis states that the ratio is higher than 0.45.

In the options provided, the proportion for the first option is 300/1000, or 0.3.

In the second choice, 500/1000 equals 0.5

Third alternative: 700/1000 = 0.7

Therefore, the stronger the evidence is against the null hypothesis, the higher the divergence from it.

To learn more about the null hypothesis from the given link.
