Any proper CDF
has the properties
• 
• 
so we have to have a = 0 and b = 1.
This follows from the definitions of PDFs and CDFs. The PDF must satisfy

and so


Answer:
x = 22
Step-by-step explanation:
x-10=12
We want to solve for x
Add 10 to each side
x-10+10=12+10
x = 22
First rounding off the both values..
Answer = 53300 * 600
= 31980000
%age error = [(53300*600 - 53320*599) / (53320*599) ]*100
=0.1%
No Jeff is wrong, -2 has a higher value than -3.
