A report describes the results of a large survey that was conducted for the Center for Disease Control (CDC). The sample was selected in a way that the CDC believed would result in a sample that was representative of adult Americans. One question on the survey asked respondents if they had learned something new about a health issue or disease from a TV show in the previous 6 months. Data from the survey was used to estimate the following probabilities, where
L = outcome that a randomly selected adult American reports learning something new about a health issue or disease from a TV show in the previous 6 months
and
F = outcome that a randomly selected adult American is female
Data from the survey were used to estimate the following probabilities:
P(L)= 0.58 P(F)= 0.50 P(L and F)= 0.31
Are the outcomes L and F independent? Use probabilities to justify your answer.
Answers
Answer:
Since [tex]P(L \cap F) \neq P(L)P(F)[/tex], the outcomes L and F are not independent.
Step-by-step explanation:
Independent events:
Two events, A and B are independent, if:
[tex]P(A \cap B) = P(A)P(B)[/tex]
Are the outcomes L and F independent?
We are given that:
[tex]P(L \cap F) = 0.31[/tex]
Multiplication of the probabilities:
[tex]P(L)P(F) = 0.58*0.5 = 0.29[/tex]
Since [tex]P(L \cap F) \neq P(L)P(F)[/tex], the outcomes L and F are not independent.

Is the a discrete random variable, a continuous random variable, or not a random variable? A. It is a random variable. B. It is a random variable. C. It is not a random variable.
Answers
Answer:
Discrete variables are those whose distribution will only take a finite number of values which are represented by integer values only.
Continous variables on the other hand could have an infinite number of points inbetween two integer values. With the values inbetween being decimals.
Step-by-step explanation:
a. The number of textbook authors now sitting at a computer :
A discrete random variable
Number of authors will be an integer value.
b. The height of a randomly selected giraffe ;
Continous random variable
Possible height value : h > 0
c. The responce to the survey question "Did you smoke in the last week"
It is not a random Variable
The response isn't numeric
d. The amount of rain in City B during April

increasing on 0 < x < 2f(2) = 4decreasing on 2 < x < 5Step-by-step explanation:
You need to know that an even function is symmetrical about the y-axis. The graph to the right of the y-axis is the mirror image of the graph to the left. With that in mind, the questions are easily answered.
It might help to draw the function graph, as we did in the attached. Then it is more straightforward to see what is happening in each of the intervals.
The function is increasing in the interval 0 < x < 2.
The function value at x=2 is 4: f(2) = 4.
The function is decreasing in the interval 2 < x < 5.

Hank’s Fried Chicken has $1,692 extra this month to give its employees as a bonus. Each employee received $53 as their bonus. How many people work for Hank’s Fried Chicken?
Answers
Given:
Total amount of bonus = $1,692
Bonus received by each employee = $53
To find:
The Number of people work for Hank’s Fried Chicken.
Solution:
We need to divide the total bonus by the bonus of each employee to get the number of people work for Hank’s Fried Chicken.
[tex]\text{Number of people}=\dfrac{\text{Total amount of bonus}}{\text{Bonus received by each employee}}[/tex]
[tex]\text{Number of people}=\dfrac{1692}{53}[/tex]
[tex]\text{Number of people}=31.92453[/tex]
Number of people must be whole number. So, approx the value to the preceding whole number.
[tex]\text{Number of people}\approx 31[/tex]
Therefore, 31 people work for Hank’s Fried Chicken.

What is the solution to the system of equations graphed below?
y = 4x + 11
y = -2x - 1
Answers
Answer:
Step-by-step explanation:
y = 4x + 11, and y = -2x - 1, so
4x + 11 = -2x - 1
6x + 11 = -1
6x = -12
x = -2
y = 4x+11 = 3
y = 4x + 11
y = -2x - 1
4x + 11 = -2x - 1
4x + 2x = -1 - 11
6x = -12
x = -12/6
x = -2
y = 4x + 11
y = 4(-2) + 11
y = -8 + 11
y=3

Step-by-step explanation:
So we substitute the point given x=-5 and y = -3 to see if this solves both equations at the same time so
3(-5) - 9(-3) = 12 -> -15+27 = 12 -> 12 = 12 [this one works]
8(-5) - 14 (-3) = 2 -> -40 + 42 = 2 -> 2=2 [this one works also]
Since (-5,-3) is a solution to both equations, then this is a solution to this system
Answer: Yes
Step-by-step explanation:
Here
x = -5
y = -3
3x - 9y = 12
Here if you substitute x and y,
3 * (-5) - 9 * (-3)
(-15) - (-27)
=12
8x - 14y = 2
8 * (-5) - 14 * (-3)
(-40) - (-42)
= 2

Angles 1-4 are on the top line clockwise from upper left. Angles 5-8 are on the lower line clockwise from upper left.

Answers
*see attachement for the diagram of the figure being referred to
Answer:
<1
Step-by-step explanation:
Alternate exterior angles are a pair of angles which are located on the opposite side of the transversal, outside the two parallel lines.
From the figure given, you would see that <7 and <1 lie on opposite side of the transversal and they lie on the outside of the two parallel lines that are cut across by the transversal.
Therefore:
<7 and <1 are alternate exterior angles.
