Answer:
The mean is 30 and there are 2 patients over this age.
Step-by-step explanation:
Add up 27+13+16+20+41+9+84=210
Then divide by the amount of numbers "7" so
210/7 is 30.
There are 2 patients over the age of 30.
Make sure that you are correct and do the problem twice.

the probability is 5 out of 20
x=45
Step-by-step explanation:
x/5+7-7=16-7
5/1×x/5=9×5/1
x=45
A reflection over the line y=x implies exchanging the x and y coordinates of a point. For example if you take a generic point (a,b) then its reflection over y=x is (b,a). Our point is (-1,3) so its reflection over y=x is the point (3,-1).
Then we have to translate it two units left. Translating a point left means that we are moving towards negative x values so we need to substract 2 from the x coordinate:
Finally we have to translate it 1 unit up towards positive y values so we have to add 1 to its y coordinate:
And these are the final coordinates. In the following picture you have the points you get after each step (from A to D) with the y=x line in blue:
