Bin $A$ has one white ball and four black balls. Bin $B$ has three balls labeled $\$1$ and one ball labeled $\$7$. Bin $W$ has f
nydimaria [60]

Answer:

$20

Step-by-step explanation:

Bin A:                             Bin B:                  Bin W:

white ball: 20%              $1: 75%                $8: 5/6

black ball: 80%              $7: 25%               $500: 1/6

first we can calculate the expected return of bins B and W:

expected return if the ball is black = ($1 x 75%) + ($7 x 25%) = $2.50

expected return if the ball is white = ($8 x 5/6) + ($500 x 1/6) = $90

expected return of the game = (expected return of a black ball x probability of choosing a black ball) + (expected return of a white ball x probability of choosing a white ball) =($2.50 x 80%) + ($90 x 20%) = $2 + $18 = $20

Determine the solution to the following system of equations: 2x+4y=-12 x+2y=-2
jolli1 [7]

Answer:

undefined/no solution

Step-by-step explanation:

you use elimination to solve. So multiply 2x+4y=-12 by 1 and x+2y=-2 by 2. then you subtract 2x+4y=-12 by 2x+4y=-4 and get 0y=-8. Anything divided by 0 is undefined/no solution because you can't divide anything by 0.

Arithmetic Operations with Numbers Written Using Scientific Notation <br> (7 × 10^−9)(5 × 10^5)
taurus [48]

Answer:

After multiplication number will be 3.5\times 10^{-5}

Step-by-step explanation:

We have given numbers which has to multiply using scientific notation

7\times 10^{-9}\times 5\times 10^5

We have to multiply the above number using scientific notation

We know that when two number are multiplied then there exponent power is being added

So when we multiply 7\times 10^{-9}\times 5\times 10^5 there power will be added and after multiplication number will be 35\times 10^{-4}=3.5\times 10^{-5}
