X^4 – 121
Answer:
(x^2+11)(x^2-11)
Step-by-step explanation:
You didn't list the options, but it should be:
(x^2 + 11) (x^2 - 11)
We use this formula: a^2 - b^2 = (a + b) (a - b)
Answer:
the coefficient is 3, the variable is y and the exponent is 1.
Step-by-step explanation:
the coefficient is always the number, it can stand alone, or have multiple variables attached. The variable is the letter in an equation, they also can stand alone or follow a coefficient. The exponent is not shown, but if you were to multiply y once, it would equal y.
Hope this helps.
I. Probability that Dave is a rollerblader = 50%
II. Probability that Aimee does not have kids = 75%
III. Probability that Mitch is a rollerblader = 80.65%
The required, none of the statements are correct, as of the given conditions.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
We are given a survey of a random sample of residents in a neighborhood who have kids and who also rollerblade. Let's denote the events as follows:
R: the event that a resident rollerblades
K: the event that a resident has kids
Based on the information given in the problem, we know that:
Dave does not have kids, so P(K) = 0 for Dave. Therefore, the probability that Dave is a rollerblader is 0, not 50%. So statement I is incorrect.
Aimee has never rollerbladed, so P(R) = 0 for Aimee. We don't know anything about whether Aimee has kids or not, so we cannot determine the probability that she does not have kids. So statement II is incorrect.
We don't have any information about whether Mitch has kids or not, so we cannot determine the probability that Mitch is a rollerblader. Therefore, statement III is also incorrect.
Therefore, none of the statements are correct.
