Answer: n=-36
Step-by-step explanation:
Let the number be n
2 fewer than a doubled number can be written as 2n-2
The number decrease by 38,can be written as n-38
Equate both
2n-2=n-38
Collect like terms
2n-n=-38+2
n=-36
The number is -36
Answer:
The expected value of the random variable with the given probability distribution = 12 .52
Step-by-step explanation:
Given data
x : 0 1 5 10 1000
p(x) : 0.33 0.32 0.24 0.10 0.01
<em>The expected value of the given random variable of given probability distribution</em>
<em>E(X) = ∑ x p ( X = x)</em>
E(X) = 0 × 0.33 + 1 × 0.32 + 5 × 0.24 + 10× 0.10 + 1000×0.01
<em>E (X) = 12.52</em>
