Answer:
A strong positive correlation
Step-by-step explanation:
A strong correlation when the correlation coefficient is close to 1 or -1. If the correlation coefficient is close to positive 1, then it is a positive strong correlation coefficient. If the correlation coefficient is close to negative 1, then it is a negative strong correlation coefficient.
Answer:
no solutions
Step-by-step explanation:
3(-n+4)+5n=2n
Distribute
-3n +12 +5n = 2n
2n+12 = 2n
Subtract 2n from each side
12 = 0
This is never true so there are no solutions
Using the property that anything over 0 is undefined, we can set x+2 to 0 and solve it to find the undefined points.
So when x is -2, the equation will be undefined because of the rules about division by zero.
Answer:
a: 70 degrees, b: 140 degrees
Step-by-step explanation:
Each of the sets of angles must add up to 180 degrees.
180 - 110 = 70
180 - 40 = 140
Answer:
the perimeter is 30 units
