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: 57.5%
Step-by-step explanation:
Because....
23/40 =
23 ÷ 40 =
0.575 =
0.575 × 100/100 =
0.575 × 100% =
(0.575 × 100)% =
57.5%
* <em>Therefor, the correct answer would be 57.5% .</em>

Use the equation 300⇒5x to find how much tim made each day on average.
x⇒60 so, Day 1: $60, Day 2: $70 etc.. so the equation 300=5x+10 suffices the problem. 300⇒5x+10 ⇒ 290=5x
x=58
So, Tim earned $58 his first day. Hope this helped.
8.25x= 15 so....
15/8.25=x so....
1.81~=x so....
