The answer is 9x^2-4=y because when you inverse an equation you reverse it.

First swap the x and y variable, then isolate y.

y = 9x^2 - 4
x = 9y^2 - 4
x + 4 = 9y^2
(x+4)/9 = y^2

plus or minus
\sqrt{((x + 4) \div 9}  = y

Determine whether the following probability experiment represents a binomial experiment and explain the reason for your answer.
allochka39001 [22]

Answer:

No. See explanation below.

Step-by-step explanation:

Since the cards are being selected <u>without replacement,</u> every time we select a card, <u>the probability varies</u> (since there is one less card) and therefore, the probability doesn't remain the same for every trial and therefore, the probability of success changes for every trial.

It is because of this that this probability experiment doesn't represent a binomial experiment.
