Less would be the answer for both i think :P im late XD
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
Answer:
C=30
Step-by-step explanation:
Supposing that we have the lines
x+2=10y
and
3x+6=Yc.
Note that dividing by 3 the second line can be rewritten as
x + 2= Y c/3.
Remember that a line is written as 
, in our case, both lines have 
and 
. Therefore, in orther that the two lines are equal, we need that 
, hence 
Answer:
n > -14
Step-by-step explanation:
Firstly, you use the distributive property;
-12 - 6n > 72
Then, since 12 is negative, you add 12 to both sides;
-12 - 6n > 72
+12 +12
-6n > 84
Then you divide both sides by -6 to get n > -14.
Shoot, hold on; this is an edit; did you mean that 72 is greater than -6(2 + n) or did you accidentally flip the sign in the picture? Hopefully I did what you needed.
