The answer to this question is -2
When we consider Linear Correlation between two numerical sets, there can be 3 possible relations
a) Positive Association
b) Negative Association
c) No Association
Negative Association or Negative Correlation refers to such a relation in which if values in one data set are being increased, the values in the other data set will decrease, resulting in a negative association. Such data sets always have the value of correlation coefficient between 0 and -1 i.e. a negative value.
Answer:
As both these angles form a linear pair, they together will form 180°
So,
(2x + 45)° + x = 180°
=> 2x + 45 + x = 180°

Answer:
one real solution
Step-by-step explanation:
We can use the discriminant to find the types of solutions
b^2 -4ac where ax^2 +bx+c=0
Since
x^2 -8x+16 =0
we know a=1 b=-8 and c=16
(-8)^2 - 4(1)(16)
64 -64 = 0
If the discriminant > 0 we have two real solutions
If the discriminant = 0 we have 1 real solutions
If the discriminant < 0 we have two complex solutions
Since it equals zero, we have one real solution
