The expression of 25t +45m shows the total number of miles driven at both speeds. In order to solve this equation you would need to know the total number of hours driven in order to multiply that by the appropriate speed in terms of miles per hour.

A glass is 2/3 full. Then 40cm3 of orange juice is poured in. The glass is now 4/5 full. What is the total volume of the glass?
mafiozo [28]

Answer:

300 cm³

Step-by-step explanation:

Volume of the glass filled with orange juice:

4/5-2/3= 12/15-10/15= 2/15

2/15 of glass = 40 cm³

Total volume of the glass:

40 cm³ ÷ 2/15= 40 cm³ × 15/2= 300 cm³

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.
