20. Suppose random variable Х is continuous
2x
0<x<1
f(x) = 1
0, otherwise
a. Check f(x) is a pdf? (1 pts)
b. Find p (x >0.5)? (2 pts)
c. Calculate E(x) and Var(x)? (​

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

hope this !

-1/3(x+1)^5

i’m pretty sure this is correct

the furthest the dog can be is 508 meters away from the house, and the closest he can be is 492 meters away from the house.
