Answer: on the first day, they hiked 9 miles.
On the second day, they hiked 16 miles.
Step-by-step explanation:
Let x represent the distance that the two hikers hiked from the first mountain to the second mountain.
Let y represent the distance that the two hikers hiked from the second mountain to the hollow.
The total distance is 25mi. This means that
x + y = 25 - - - - - - - - - - - - - -1
If the distance between the second mountain and the hollow is 7mi more than the distance from the first mountain to the second mountain, it means that
y = x + 7
Substituting y = x + 7 into equation 1, it becomes
x + x + 7 = 25
2x = 25 - 7
2x = 18
x = 18/2 = 9
y = x + 7 = 9 + 7
y = 16
from the given answers there is no answer
m=15
n=19
I am not sure but I think you have to multiply 538 and 9 and get 4842 then divide 4842 by 15 and get 322.8. ( I am not sure if I'm right ).
A correlation coefficient is always a value in between -1 and 1
The closest a coefficient to -1, the correlation is a strong negative correlation
The closest a coefficient to 1, the correlation is a strong positive correlation
The closest a coefficient to 0, there is no correlation at all
The coefficient -0.61 shows a strong negative correlation
This means that the relationship between the age and the violation is an inverse relationship; as age increases, violation decreases
Answer: option C
