4y-5/y^2-3y+2
4y-5/(y-2)(y-1)
651 - 376 ≈650 - 380 ≈ 270
Answer: The option B. 1.9 is correct
Explanation:
We are given the below information:
x Probability P(x)
0 0.2
1 0.1
2 0.4
3 0.2
4 0.1
The expected value of x is given below:
Therefore, the expected value of x is 1.9
Answer: Division of Polynomials is just like the long division that most of us despise but this division is with Variables
Step-by-step explanation:
Example
With whatever equation you have you will
- First: set up the division putting the dividend inside the divisor outside and to the left
- Second: Ignore everything past the leading terms and just focus on the leading _ of the divisor and the leading _ of the dividend (just like in regular long division.
- Thirdly: Take whatever is on top and multiply is by the divisor {What is on the side} carry the result underneath put it exactly below the number from the dividend
- Fourth: Multiply the number that is on top by the number that is on the side, carry what is on the side underneath putting it below the other dividend.
- Fifth: Do the subtraction
- Sixth To subtract change all the signs in the second line, then add down.
- Next: Carry down that last term from the dividend
- From there you multiply and then add down again and you should be left with the answer....
If this was to many words let me know and I will upload a picture and explain with a real equation.
