Answer:
μ = 1 The firm expects that one oil exploration will be successful.
v(x)= 0.9
Step-by-step explanation:
The first step is to define the random variable x as:
x: number of oil explorations being succesful
Then x can be take this values:
x = 0 , x =1 ... x =10
x is a binomially distributed random variable with parameters.
p = 0.1 and n=10
And the mean or the expected value of x is:
μ = E(x) = np
Then μ = 10*0.1 = 1
And the variance of x is:
V(x) = np(1-p)
V(x) = 10(0.1)(1-0.1)= 0.9
Resposta: f ^ (- 1) (x) = (1/2) x-1/2
Answer:
They are equal. x= -24
Step-by-step explanation:
-2x - 7 ≥ 41
First you isolate the variable
-2x -7 ≥ 41
+7 +7
-2x≥48
then divide each side by -2
x≥-24
Then go back and plug in
-2(-24)-7=
48-7=41
Therefore
41=41
The answer for your question is x=-1
Answer:
D) 12
Step-by-step explanation:
divide each term by -8 and simplify
-8/-8x=-96/-8
x=12
