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.

Answer:
1. dave has a low chance of rollerblading if he is focusing on his career.
Step-by-step explanation:
y=-x+34 it is a substitution method
=
7:02
True or false
Answer:
30.6
Step-by-step explanation:
The area of a parallelogram is base * height.
Base = 6.8
Height = 4.5
6.8 * 4.5 = 30.6
Just answering so Adriantan2019 can get brainliest because that was a good answer and I don't remember how to do the area! SORRY! :) Have a great day! :)
A 3x - 1 = 3x + 1
® 2x - 1 = 1 - 2x
© 3x - 2 =2x-3
D 3(x - 1) = 3x - 3
Answer:
D
Step-by-step explanation:
In order to have infinitely many solutions, the lines must be the same.
If we solve D by using the distributive property, we end up withe 3x-3=3x-3.
3x-3 and 3x-3 are the same lines and intersect infinitely many times, therefore the correct answer is D.
3x3 - 8x+7
The question involves division of two polynomials, 2x3 + 4x - 6 by 3x3 - 8x + 7. However, a direct division of these polynomials is not feasible since degree of the divisor is not less than the degree of the dividend.
This question is about polynomial division. In this case, the student is being asked to divide one polynomial 2x3 + 4x - 6 by another polynomial 3x3 - 8x + 7.
Polynomial division is quite similar to long division with numbers but here we are working with variables like x. Since division of these expressions is not straightforward, you typically use long division or synthetic division method to solve this.
However, in this case we can't divide these two polynomials directly because the degree of the divisor (degree of the polynomial in denominator, which is 3) is greater than the degree of the dividend (degree of the polynomial in numerator, which is also 3). Normally, degree of the dividend should be greater than or equal to the divisor for the division to take place.
