It is estimated that 88% of senior citizens suffer from sleep disorders and 7% suffer from anxiety. Moreover, 5% of senior citizens suffer from both sleep disorders and anxiety. a)Given that a senior citizen suffers from anxiety, what is the probability that he or she also suffers from a sleep disorder? Round your answer to the nearest hundredth. B) Find the probability that a senior citizen suffers from anxiety, given that he or she has a sleep disorder. Round your answer to the nearest hundredth.
Answer:
a) 0.71
b) 0.06
Step-by-step explanation:
We solve using Baye's Theorem
It is estimated that 88% of senior citizens suffer from sleep disorders and 7% suffer from anxiety. Moreover, 5% of senior citizens suffer from both sleep disorders and anxiety.
We have Two events
A and B
Events A = 88% of senior citizens suffer from sleep disorders
P(A) = 0.88
Event B = 7% suffer from anxiety
P(B) = 0.07
Moreover, 5% of senior citizens suffer from both sleep disorders and anxiety.
P(A and B) = 0.05
a)Given that a senior citizen suffers from anxiety, what is the probability that he or she also suffers from a sleep disorder? Round your answer to the nearest hundredth.
This is calculated as:
P(A and B)/P(B)
= 0.05/0.07
= 0.7142857143
Approximately = 0.71
B) Find the probability that a senior citizen suffers from anxiety, given that he or she has a sleep disorder. Round your answer to the nearest hundredth.
This is calculated as:
P(A and B)/P(A)
= 0.05/0.88
= 0.0568181818
Approximately = 0.06

Which equation illustrates the associative property?
1. x + y + z = x+y+z
2. x(y + 2) = xy + XZ
3. x+y+z= z + y + x
4. (x + y) + z = x + (y + z)
Answer:
four
Step-by-step explanation:
the associative property is when what ever is in the parentheses can be moved around and it won’t matter because I’ll give the same answer. One dosent have parenthese, two does but the x will distribute into the equation, three there is no parentheses, and four has parentheses and you can’t distribute.

Mia has $50 on a gift card to her favorite coffee shop. Each time she visits the coffee shops she spends $3.75 on her favorite drink. Choose the equation that represents the relationship between x, the number of times she visits the coffee shop, and y, the total amount on her gift card.
Given:
Value of Gift card = $50
Each time she visits the coffee shops she spends $3.75 on her favorite drink.
To find:
The equation for the given situation.
Solution:
Let x be the number of times she visits the coffee shop, and y be the total amount on her gift card.
Cost of her favorite drink for one time = $3.75
Cost of her favorite drink for x times = $3.75x
Value of gift card is $50. So,
Amount on her gift card = 50 - Cost of her favorite drink for x times
[tex]y=50-3.75x[/tex]
Therefore, the required equation is [tex]y=50-3.75x[/tex].

In a sequence, each number after the first number is obtained by adding 4 to the previous number. If the first number in the sequence is 7, which of the following expressions represents the nth number in the sequence?
A 7+4n
B 7+(4n−1)
C 7+4(n−1)
D 7+4(n+1)
Expression (C) [7 + 4(n - 1)] represents the nth number in the given arithmetic sequence.
What is an arithmetic sequence?A series of numbers called an arithmetic progression or arithmetic sequence has a constant difference between the terms. An arithmetic progression with a common difference of 2 is found, for instance, in the numbers 5, 7, 9, 11, 13, and 15. Starting with a number and repeatedly adding a fixed constant (d) to it is an easy technique to create a series.So, in the arithmetic sequence, there is a formula to find the nth term in the series.
Formula for aₙ term is: aₙ = a₁ + d(n - 1)Where d is the common difference and n is the number of terms.Here, d is 4 and a₁ is 7.Then, For aₙ term:
aₙ = a₁ + d(n - 1)aₙ = 7 + 4(n - 1)Therefore, expression (C) [7 + 4(n - 1)] represents the nth number in the given arithmetic sequence.

The diameter of a circle swimming pool is 15 ft find the circumference to the nearest hundredth
The circumference of the circular swimming pool is given by C = 47.12 feet
What is a Circle?A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
The equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
Given data ,
Let the circumference of the circular swimming pool be C
Now , the diameter of the swimming pool D = 15 feet
So , the radius of the circular pool r = D / 2
The radius r = 7.5 feet
Now , circumference of circle = 2πr
So , on simplifying , we get
The circumference of the circular swimming pool C = 2π ( 7.5 )
The circumference of the circular swimming pool C = 15π
The circumference of the circular swimming pool C = 47.12 feet
Hence , the circumference of the circular swimming pool is 47.12 feet

which equation is equivalent to 19x+12y=17?
Answer:
A
y=-19/12x+17/12
Step-by-step explanation:
Write in slope-intercept form,y=mx+b
The equation i.e. 19x + 12y = 17 equivalent to the [tex]y = \frac{19}{12}x + \frac{17}{12}[/tex].
Given that,
The equation i.e. 19x + 12y = 17.We need to find the equation i.e. equivalent to the above.Based on the above information, the calculation is as follows:
19x + 12y = 17
Here we need to solve it for y
[tex]y = \frac{19}{12}x + \frac{17}{12}[/tex]
Therefore, we can conclude that the first option is correct.
