2x-8=x+4
Get the x to the other side and the 8 to the opposite
2x-x=4+8
X=12
X=5/8 or x=-4/3
here is the work if needed...
24x^2+17x-20=0
Step one: Factor left side of equation.
(8x-5)(3x-4)=0
Step two: Set factor equal to 0.
8x-5=0 or 3x-4=0
x=5/8 or x=-4/3
<span>£1 equals to 1.43 us dollars.
7 </span>× 1.43 = <span>10.01
</span>10.01 ÷ 5 = <span>2.002

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
