Answer: d. There is no relationship between education level and smoking habits.
Step-by-step explanation:
The null hypothesis is the affirmation that two parameters or phenomena do not have a relation between them.
Here the parameters are smoking and having a bachelor's degree or higher education.
Then the null hypothesis says that those two things do not have any relation, this would imply that the probability of being a smoker does not depend on having a degree or not.
Then the correct option is d "There is no relationship between education level and smoking habits."
Answer:
16.3 repeating
Step-by-step explanation:
3x-4(4)=65
3x-16=65
3x=65-16
3x=49
x=49/3
x=16.3 repeating
Answer:
a. Domain - x= all real numbers
b. Domain - x= all real numbers except 0
c. Domain - x= all real numbers
d. Domain - x= All real numbers
Step-by-step explanation:
The domain of a function is all the possible x values. It is easy to solve for domain by graphing the function.
a graph - blue
b graph - red
c graph - green
d graph - purple
Answer:
Step-by-step explanation:
<u>Even function has following property:</u>
<u>It is easy to show this works with the second choice only. All the others don't work:</u>
- g(x) = (x - 1)² + 1
- g(-x) = (-x - 1)² + 1
This is not correct as x - 1 ≠ -x - 1 so as their squares, so g(x) ≠ g(-x)
The last two choices are not even similarly.
