You want to find the value of x for which the area under the curve to the left of x is 0.6. One way to do that is to create the cumulative distribution function (CDF) for the given PDF, then see where it is equal to 0.6.
Doing that, we find a = 5.
When you divide something by 10, yo move the decimal place one place to the left so exg
20.0/10=2.0
so divide by 1000 means move the decimal place 3 places to the left so if you had 20,000.0/1000=20.0 so
6.82/1000=0.00682
5/2 is already in its simplest form. You cannot reduce this fraction any further.
I am assuming that the second equation is
. In that case, the correct answers are (0, -1) and (3, -8).
