A distribution of probabilities for random outcomes of a bivariate or dichotomous random variable is called a Group of answer ch
slega [8]

A distribution of probabilities for random outcomes of bivariate or dichotomous random variables is called (A) binomial probability distribution.

<h3>What is a binomial probability distribution?</h3>
  • The binomial distribution with parameters n and p in probability theory and statistics is the discrete probability distribution of the number of successes in a succession of n separate experiments, each asking a yes-no question and each with its own Boolean-valued outcome: success or failure.
  • The binomial distribution is widely used to describe the number of successes in a sample of size n selected from a population of size N with replacement.
  • If the sampling is done without replacement, the draws are not independent, and the resulting distribution is hypergeometric rather than binomial.
  • Binomial probability distribution refers to a distribution of probabilities for random outcomes of bivariate or dichotomous random variables.

As the description itself says, binomial probability distribution refers to a distribution of probabilities for random outcomes of bivariate or dichotomous random variables.

Therefore, a distribution of probabilities for random outcomes of bivariate or dichotomous random variables is called (A) binomial probability distribution.

Is x a solution to 80&lt;-9x+8
saveliy_v [14]

Answers: x

1. Switch sides

-9x+8>80

2. Subtract by 8 from both sides of equation.

-9x+8-8>80-8

3. Simplify.

-9x>72

4. Multiply by -1 from both sides of equation. (it's should be the reverse inequality).

(-9x)(-1)

5. Simplify.

9x

6. Then you had to divide by 9 from both sides of equation.

\frac{9x}{9}< \frac{-72}{9}

7. Simplify.

\frac{9x}{9}=x

8. Divide by the numbers.

\frac{9}{9}=1

=x

\frac{-72}{9}=-8

9. Divide by the numbers.

\frac{72}{9}=8

=-8

x
