Answer:
A. 0.75
B. Elsa can expect to gain 0.75 dollars
Step-by-step explanation:
We have six outcomes
Using the table in the attachment, the expected value was calculated.
Expected value = 0.166667+0.3333+0.5-0.083333-0.083333-0.083333
= 0.75
B. From the answer in part A , we can conclude that Elsa can expect to gain money. She can expect to win 0.75 dollars per roll.
Answer:
The answer is w^2 + 2xw + x^2
Answer:
y = 2x - 3
Step-by-step explanation:
Let (2, 1) = ![(x_1,y_1)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29)
Let (4, 5) = ![(x_2,y_2)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29)
Slope formula: ![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
![\implies m=\dfrac{5-1}{4-2}=2](https://tex.z-dn.net/?f=%5Cimplies%20m%3D%5Cdfrac%7B5-1%7D%7B4-2%7D%3D2)
Equation of a line, point-slope formula: ![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
![\implies y-1=2(x-2)\\\\\implies y=2x-3](https://tex.z-dn.net/?f=%5Cimplies%20y-1%3D2%28x-2%29%5C%5C%5C%5C%5Cimplies%20y%3D2x-3)
