Answer:

(C). ​(Probability of state A*Value in state A)+(Probability of state B*Value in state B)

Step-by-step explanation:

The expected value of a probability distribution, E(X) is defined as:

E(x)=\sum_{i=1} ^{k} x_{i} \cdot P(x_{i})\\$Where x=An Outcome\\P(x)=Probability of that Outcome

Given Outcome A and B, the Expected Value  therefore is:

Expected Value = ​(Probability of state A*Value in state A)+(Probability of state B*Value in state B)

Gala2k [10]

Answer:

(-8 , 3)

Step-by-step explanation:

(x1 , y1)   (x2 , y2) = (-10 , -1) (-6 , 7)

\frac{-6-10}{2} ,  \frac{7-1}{2}   -6 is going to be my x1 and -10 my y1

                     7 is going to be my x2 and -1 my y2

2/7x = 10 show work plz
Rashid [163]

Answer:

x = 35

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2/7*x-(10)=0

                 2

Simplify   —

                  7

  2        

 (— • x) -  10  = 0

  7        

Subtracting a whole from a fraction

Rewrite the whole as a fraction using  7  as the denominator :

             10             10 • 7

   10 =  ——  =  ——————

               1                 7  

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

           2x - (10 • 7)                       2x - 70

—————————————  =  ———————

                     7                                   7  

Pull out like factors :

  2x - 70  =   2 • (x - 35)

         2 • (x - 35)

 ————————————  = 0

                 7      

When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

      2•(x-35)

 ———————— • 7 = 0 • 7

          7    

Now, on the left hand side, the  7  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  2  •  (x-35)  = 0

Solve :    2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solve  :    x-35 = 0

Add  35  to both sides of the equation :

                     x = 35
