I’m not 100% sure but I think it’s because 20/25 can still be simplified further, while the other 3 can’t.
In 1 meter is 10 decameters. In 14 meters=140 decameters
-1
I think I got this wrong I'm sorry if I couldn't help
Factor 3x^3-10x^2+3x+10
=(x-2)(3x^2-4x-5)
Answer:
Follows are the solution to the given points:
Step-by-step explanation:
Given value:
For point a:
Moment generating function of X=?
Using formula:


integrating the values by parts:
Therefore, the moment value generating by the function is 
In point b:
Using formula:

form point (a):

Differentiating the value with respect of t

when
