The problem involves empirical probability. the table shows the breakdown of 95 thousand single parents on active duty in the u. s. military in a certain year. all numbers are in thousands and rounded to the nearest thousand. use the data in the table to find the probability that a randomly selected single parent in the u. s. military is in the army.

Since it doesnt matter if parent is male or female, there are total of 38 000 single parents in the army

There are total of 95 000 single perents serving in military that means that probability that randomly selected single perent is in the army is:
38000/95000 = 38/95 = 0.4

If you want that in percentage just multiply it with 100%
in that case answer is 0.4*100 = 40%

The coordinates of point a right now is (-3,-1) you have to multiply these coordinates by a factor of 2 to get (-6,-2)
