Answer: Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.
Step-by-step explanation:
Since we have given that
Number of coffee drinkers = 10000
Number of whom developed anxiety = 500
Number of non coffee drinkers = 20000
Number of whom developed anxiety = 200
So, probability of getting anxiety from coffee drinkers = 
Probability of getting anxiety from non coffee drinkers = 
so, Relative risk of anxiety associated with coffee use is given by

Hence, Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.

Let's solve for x ~

[ by vertical opposite angle pair ]




Therefore, the correct choice is D. 6
Answer:
F (-8, -1)
Step-by-step explanation:
We can solve the system using substitution.
From the second equation
x-6y= -2
x= -2 + 6y
This value of x substitute into 1st equation
-4x+5y=27
-4(-2+6y)+5y=27
8-24y+5y =27
- 19y = 19
y= -1
x= -2 + 6y, y= - 1
x= -2 +6(-1)= -8
x= - 8
x= -8, y= -1
(-8, -1)
