To solve this problem, we should set up an equation, letting the unknown number be represented by the variable x.
2/3x = 20
To solve this equation, we just have to divide both sides of it by 2/3, because we are trying to get the variable alone on the left side of the equation.
x = 30
Therefore, the number is 30.
Answer:
2
Step-by-step explanation:
The correct options are:
A. The scatter plot has an outlier at (15, 2)
B. The scatter plot has a cluster with a range from 2 to 4
<u><em>Explanation</em></u>
Co ordinate of any point can be written in form of (x,y) where first value is the distance across x-axis and second value is the distance across y-axis.
We can see in the plot, that the outlier point is 15 unit across x-axis and then 2 unit across y axis from the origin. So the co ordinate of that point will be (15, 2).
Range means the values across the y-axis. We can see that the cluster starts at y=2 and ends at y=4. That means, the scatter plot has a cluster with a range from 2 to 4.
