After careful testing and​ analysis, an oil company is considering drilling in two different sites. It is estimated that site A

will net ​$30 million if successful​ (probability .4​) and lose ​$4 million if not​ (probability .6​); site B will net ​$60 million if successful​ (probability .3​) and lose ​$8 million if not​ (probability .7​).
Which site should the company choose according to the expected return from each​ site?

Answer:

Expected return for site A = $9.6 million

Expected return for site B = $12.4 million

according to the above results the company should choose SITE B because it has higher Expected return

Step-by-step explanation:

Given;

For site A,

Site A net if successful = $30 million

Success probability = 0.4

Site A loss if not successful= -$4 million

Probability of not successful = 0.6

For site B.

Site B net if successful = $60 million

Success probability = 0.3

Site B loss if not successful= -$8 million

Probability of not successful = 0.7

To estimate the expected return on an event with outcomes X1 and X2 with probabilities p1 and p2

E = X1(p1) + X2(p2)

Substituting for site A

E = 30(0.4) - 4(0.6)

E = $9.6 million

Substituting for site B

E = 60(0.3) - 8(0.7)

E = $12.4 million

Therefore, according to the above results the company should choose site B because it has higher Expected return

GenaCL600 [577]

I believe it's E.) 12.96


12 times 8% equals .96 so $12.96 should be the answer since it wants the final price with tax :DD

Fill in the blanks below in order to justify whether or not the mapping shown
Fantom [35]

Let's start with the fact that this is a function.  Each element of Set A is paired with exactly one element of Set B.

This makes Set A the set of inputs and Set B the set of outputs.

There are a lot of other boxes to pick from, so I'm not sure what else you'd need to pick to make your answer correct.

When 7 is subtracted from two third of the square of a number it becomes 17 find the number​
Dmitry [639]

Answer:  6 or -6

hello,

Step-by-step explanation:

Let say n the number

\dfrac{2}{3} *n^2-7=17\\\Longrightarrow\ \dfrac{2}{3} *n^2=24\\\Longrightarrow\ n^2=\dfrac{3*24}{2}\\\Longrightarrow\ n^2=36\\\Longrightarrow\ (n-6)(n+6)=0\\\\n=6\ or\ n=-6\\

Find the complex fourth roots \[-\sqrt{3}+\iota \] in polar form.
____ [38]

Let z=-\sqrt3+i. Then

|z|=\sqrt{(-\sqrt3)^2+1^2}=2

z lies in the second quadrant, so

\arg z=\pi+\tan^{-1}\left(-\dfrac1{\sqrt3}\right)=\dfrac{5\pi}6

So we have

z=2e^{i5\pi/6}

and the fourth roots of z are

2^{1/4}e^{i(5\pi/6+k\pi)/4}

where k\in\{0,1,2,3\}. In particular, they are

2^{1/4}e^{i(5\pi/6)/4}=2^{1/4}e^{i5\pi/24}

2^{1/4}e^{i(5\pi/6+2\pi)/4}=2^{1/4}e^{i17\pi/24}

2^{1/4}e^{i(5\pi/6+4\pi)/4}=2^{1/4}e^{i29\pi/24}

2^{1/4}e^{i(5\pi/6+6\pi)/4}=2^{1/4}e^{i41\pi/24}
