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.

Answer:
1. dave has a low chance of rollerblading if he is focusing on his career.
Step-by-step explanation:
II. Factor the quadratic expression. Rewrite the equation with factors instead of the original polynomial.
III. Use the zero product property to solve the quadratic equation.
IV. Rewrite your solutions to Part III by replacing u with sin x.
V. Solve the remaining equations for x, giving all solutions to the equation.
we have that
I. Rewrite the equation by substituting the expression u in for sin x.
II. Factor the quadratic expression. Rewrite the equation with factors instead of the original polynomial.
is equal to
using a graph calculator-----> see the attached figure
III. Use the zero product property to solve the quadratic equation.
(u-3)=0--------------> u=3
(2u+1)=0-------- 2u=-1------> u=-1/2-----> u=-0.5
IV. Rewrite your solutions to Part III by replacing u with sin x.
sin x=3--------> is not the solution (sin x can not be greater than 1)
sin x=-0.50------>is the solution
V. Solve the remaining equations for x, giving all solutions to the equation.
sin x=-0.50
if the sine is negative
then
x belong to the III or IV quadrant
we know that
sin 30°=0.50
so
the solution for the III quadrant is
x=180°+30°-------> x=210°
the solution for the IV quadrant is
x=360°-30°------> x=330°
12 is
times as many as 4.
Answer:
12 is equal to 3 times 4 (3 * 4 = 12)
Step-by-step explanation:
Given that:
12 = 4 * 3
means that:
12 is three(3) times as many as 4.
OR
it can also be explained like when 4 is added 3 times it gives 12:
Mathematically:
4+ 4+ 4 = 12
i hope it will help you!
This is an example of the Associative Property of addition.
Answer:
3/4
Step-by-step explanation:
because it is how far away it is from 0 on the other side
Answer:
Step-by-step explanation:
we know that
The rule of the translation is equal to
Find the values of a and b
we have that
---->
---->
substitute the values of a and b
That means----> The translation is 9 units right and 12 units down
Answer:
Option D:
(x, y) -> (x + 9, y minus 12)
Step-by-step explanation: Honestly all people want are the answers so I don't really care to write an explanation.
