HELP PLEASE RNNNNNN
GalinKa [24]

Answer:

The three statements on the right hand side of the screen are the correct ones

Step-by-step explanation:

To take the average of the weight of the cat in the month of April is the following:

9.8 + 9.6 + 9.7 + 9.5 + 9.4 = 48

But then divide that by the number of samples:

48/5=9.6

The mean for April is 9.6

To take the average of the weight of the cat in the month of November is the following:

9.4 + 9.3 + 9.1 + 9.2 + 9 = 46

But then divide that by the number of samples:

46/5=9.2

Then, lastly, subtract the mean from November by the mean of April:

9.6-9.2=0.4

- Does the graph below represent a function? How do you know? please answer! ​
andrezito [222]

Answer:

No, the graph does not represent a function because it does not pass the vertical line test.

<h2>What is a function?</h2>

A function is when each x-value only has one y-value. We know that a graph represents a function if it passes the vertical line test.

<h3>Vertical Line Test</h3>

To pass the test, any vertical line that we draw on the graph should only touch one point.

A vertical line is a straight line that goes from top to bottom.

  1. Draw vertical lines through points on the graph, like in the photo below.
  2. Check if any vertical lines touch more than one point.

The yellow vertical line touches two points, which is more than one. So, the graph does not pass the test. This graph is does not represent a function.
