Answer:
8.7
Step-by-step explanation:
To find the mean first you have to add up all the weight of the cats which is:
After, you have to divide the total weight by the number of cats there are
which is:
Since, this is a really long number you would normally round the number to the nearest tenth which is 8.7
The second one doesn't represent a function, because for some values of "x", you get two different values for "y" (which should not happen, if that were a function).
In every function, you must have a single "y" value for each "x" in the domain.
__________
In order to see it better, you can trace a vertical line onto that graph.
If that line and the graph intersects in more than one point, then that graph doesn't represent a funcion.
Look into the attached picture and see. That vertical red line and the graph intersects in two distinct points. Therefore, it can't represent a function.
Any doubt? Please, comment below.
I hope it helps. :-)
