Answer:
The number of months cost same is 9
Step-by-step explanation:
Given:
Equation for the first plan y = 38x + 15
Equation for the second plan y = 31x + 78.
where x is the number of month
Solution:
38x + 15 = 31x + 78
7x + 15 = 78
7x = 63
x = 9
Answer:
6?
Step-by-step explanation:
The first one might be cannot be determined
2- rational
3- irrational
The probability of one success and one failure will be 4/9. Table C represents the probability distribution for the variable X.
<h3>What is probability?</h3>
The chances of an event occurring are defined by probability. Probability has several uses in games, in business to create probability-based forecasts,
The dials on the spinner are spun 2 times in a row.
P(dial lands on region)=P(success) = 2/3
P(failure) = 1/3
The probability that the two times dials on the spinner are not spun 2 times in a row.
P = (1/3)² = 1/9
The probability that the two times dials on the spinner are spun 2 times in a row.
P = (2/3)²= 4/9
One may calculate the probability of one success and one failure using the binomial distribution or by simply deducting the probabilities we previously determined from 1.
P = 1 - 1/9 - 4/9
P = 4/9
The probability of one success and one failure will be 4/9.
Hence table C represents the probability distribution for the variable
X.
