Step-by-step explanation:
Discrete data can only have certain values. For example, if you roll a die, there are only 6 numbers you can get. Continuous data can have any value within a range.
Graphically, discrete data will appear as only points, where as continuous data appears as a line or curve.
So the top left and bottom right graphs are discrete. The top right and bottom left graphs are continuous.
To be a function, each x value can only have 1 y value. Graphically, we can check this using the "vertical line method". Imagine a vertical line (or use a ruler or straight edge) and move it from left to right. If it ever crosses the graph in two or more places, the graph is not a function.
Therefore, the graphs on the left are not functions, and the graphs on the right are functions.
X has to be a larger valued negative number than y for the equation to be valid.
The correct answer for the question that is being presented above is this one: "<span> C. 27% ." </span>Relative Frequency is how often something happened divided by the number of situations when it could have happened (trials). So in our examples we divide the number of outcomes by trials:
Answer:
15
Step-by-step explanation:
The total number of teachers in the school is 100.
The number who teach Science is 60
The who teach humanities is 25.
The number that teach both humanities and Science is 15.
We want to find the number who teach Science but not Humanities.
We obtain this by subtracting the number of teachers who teach both subjects from the number that teach Science.
Therefore 25 teaches science but not Humanities
