Answer:

Step-by-step explanation:

1. 6w*2v + 3*6w= 12vw + 18w

2. 7(-5v) - 7(8)= -35v - 56

3. 2x*(-2x) - 3(2x) = -4x^2 - 6x

4. -4*v - 4(1)= -4v - 4

5. 2n*6n + 2n + 2*6n + 2= 12n^2 + 14n + 2

6. 4n(2n) + 4n(6) + 2n + 6= 8n^2 + 26n + 6

7. x(6x) - 2x - 18x + 6 = 6x^2 - 20x + 6

8. 8p(6p) + 8p(2) - 2(6p) - 4 = 48p^2 + 16p - 12p - 4= 48p^2 + 4p - 4

9. 6p(5p) - 6p(8) + 8(5p) - 40= 30p^2 - 48p + 40p - 40= 30p^2 - 8p - 40

10. 3m(8m) + 3m(7) - 8m - 7 = 24m^2 + 21m - 8m - 7= 24m^2 + 13m - 7

11. 2a(8a) - 2a(5) - 8a + 5 = 16a^2 - 10a - 8a + 5 = 16a^2 - 18a + 5

12. 5n(5n) - 5n(5) + 6(5n) - 6(5)= 25n^2 - 25n + 30n - 30= 25n^2 + 5n - 30

13. 4p(4p) - 4p - 4p + 1 = 16p^2 - 8p +

14. 7x(5x) + 7x(6) -6(5x) - 6(6)= 35x^2 + 42x - 30x - 36= 35x^2 + 12x - 36

What conditions must hold for a probability distribution to be acceptable?

VashaNatasha [74]

A distribution of probabilities is a numerical means of describing all unique combinations and the probabilities for a provided random variable, and the further discussion can be defined as follows:

The distributions mean (average), basic difference, skewness, as well as courtesies, are among such factors.
A formula, table, or chart can show a probability distribution for discrete probability distribution X that providing $\bold{p(x) = P(X=x)}$ for all x.
For just a discrete random variable, the probability assigns annual probabilities with only a countless multitude of unique x values.
<em><u>Each result is likely to be between 0 and 1, including.</u></em>
