True or false..How do I know if it's no solution

Mathematics
1 answer:
Misha Larkins [42]3 years ago
4 0

Answer:

False

Step-by-step explanation:

If (8,9) is a solution, you will be able to substitute 8 for x, and 9 for y.

(-2 x 8) + (4 x 9) = -20?

-2 x 8 = -16

4 x 9 = 36

-16 + 36 = 20

So, (8,9) is not a solution to the system.

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.

theresa went bowling on tuesday night. she bowled scores of 150, 165, and 165. what was her mean average score?
aleksley [76]
So, to do this, all you need to do is add up all the values, and then, with that number, divide by how many values are given.

150+165+165= 480
480/3= 160
